Automation Solutions LLC Terms and Conditions of Sale

Customer and Automation Solutions LLC ("AS LLC") agree that the purchase and sales of AS LLC hardware and software products ("the Products")

are made under these terms and conditions, and that AS LLC SHALL NOT BE BOUND BY CUSTOMER'S ADDITIONAL OR DIFFERENT TERMS.

Customer's order and purchase of the Products shall constitute acceptance of these terms and conditions.

1. TITLE. Title to the Products shall pass at AS LLC's plant; however, if Customer is the United States or any political subdivision of the

United States, title shall pass at Customer's plant. AS LLC retains a security interest and right of possession in the Products until

Customer makes full payment.

2. TAXES. Product prices are exclusive of, and Customer shall pay, applicable sales, use, service, value added or like taxes, unless

Customer has provided AS LLC with an appropriate exemption certificate for the delivery destination acceptable to the applicable taxing

authorities.

3. PRICES AND PAYMENT. All quotations shall expire sixty (60) days from date of issuance, unless otherwise set forth on the quotation or

agreed in writing. Customer shall make payment in full prior to or upon delivery by cashier's check, credit card, or money order, unless AS

LLC approves Customer for credit terms. If AS LLC approves Customer's credit application, payment shall be due no later than 30 days

from the date of AS LLC's invoice. All sums not paid when due shall accrue interest daily at the lesser of a monthly rate of 1.5% or the

highest rate permissible by law on the unpaid balance until paid in full. Payments for orders shall be made in U.S. Dollars. In the event of

any order for several units, each unit(s) will be invoiced when shipped. Exceptions may be made for government purchase orders.

4. ORDERS. All orders are subject to acceptance by AS LLC. AS LLC's booking of an order shall constitute its acceptance of an order.

5. DELIVERY. AS LLC shall deliver the Products to a carrier at AS LLC's plant and, if the Products are sold to a Customer outside the United

States, shall clear the Products for export destined outside the United States. Customer shall pay all freight charges, applicable import

duties, and other necessary fees and shall bear the risks of carrying out customs formalities and clearance. Orders are entered as close

as possible to the Customer's requested shipment date, if any. Shipment dates are scheduled after acceptance of orders and receipt of

necessary documents. Claims for shipment shortage shall be deemed waived unless presented to AS LLC in writing within twenty one

(21) days of shipment.

6. LIMITED WARRANTY. AS LLC hardware Products are warranted against defects in materials and workmanship for one year from the

date AS LLC ships the Products to Customer. All software Products are licensed to Customer under the terms of the appropriate AS LLC

license. For a period of ninety (90) days from the Delivery Date, AS LLC software Products (when properly installed) (a) will perform

substantially in accordance with the accompanying written materials, and (b) the medium on which the software product is recorded will be

free from defects in materials and workmanship under normal use and service. Any replacement of a licensed software product will be

warranted for the remainder of the original warranty period or thirty (30) days, whichever is longer. Customer must obtain a Return

Material Authorization number from AS LLC before returning any Products under warranty to AS LLC. Customer shall pay expenses for

shipment of repaired or replacement Products to and from AS LLC. After examining and testing a returned product, if AS LLC concludes

that a returned product is not defective, Customer will be notified, the product returned at Customer's expense, and a charge made for

examination and testing. This Limited Warranty is void if failure of the Products has resulted from accident, abuse, misapplication,

improper calibration by Customer, Customer supplied third party software not intended for use with the applicable AS LLC software,

utilization of an improper hardware or software key or unauthorized maintenance or repair.

7. CUSTOMER REMEDIES. AS LLC's sole obligation (and Customer's sole remedy) with respect to the foregoing Limited Warranty shall be

to, at its option, return the fees paid or repair/replace any defective Products, provided that AS LLC receives written notice of such defects

during the applicable warranty period. Customer may not bring an action to enforce its remedies under the foregoing Limited Warranty

more than one (1) year after the accrual of such cause of action.

8. RETURN/CANCELLATION/CHANGE POLICY. Customer may return unwanted Products within thirty (30) days of the Delivery Date.

Customer shall pay a fifteen percent (15%) restocking charge on any unwanted Products returned to AS LLC. No returns will be accepted

after the thirty (30) day period has expired. Where special equipment or services are involved, Customer shall be responsible for all

related work in progress; however, AS LLC shall take responsible steps to mitigate damages immediately upon receipt of a written

cancellation notice from Customer. A Return-Material Authorization number must be obtained from AS LLC for return of any Products. AS

LLC may terminate any order if any representations made by Customer to AS LLC are false or misleading. Changes to orders shall not be

binding upon nor be put into effect by AS LLC unless confirmed in writing by AS LLC's appropriate representative.

9. NO OTHER WARRANTIES. EXCEPT AS EXPRESSLY SET FORTH ABOVE, THE PRODUCTS ARE PROVIDED "AS IS" WITHOUT

WARRANTY OF ANY KIND, AND NO OTHER WARRANTIES, EITHER EXPRESSED OR IMPLIED ARE MADE WITH RESPECT TO

THE PRODUCTS, INCLUDING BUT NOT LIMITED TO ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A

PARTICULAR PURPOSE, TITLE OR NON-INFRINGEMENT OR ANY OTHER WARRANTIES THAT MAY ARISE FROM USAGE OF

TRADE OR COURSE OF DEALING. AS LLC DOES NOT WARRANT, GUARANTEE, OR MAKE ANY REPRESENTATIONS

REGARDING THE USE OF OR THE RESULTS OF THE USE OF THE PRODUCTS IN TERMS OF CORRECTNESS, ACCURACY,

RELIABILITY, OR OTHERWISE AND DOES NOT WARRANT THAT THE OPERATION OF THE PRODUCTS WILL BE

UNINTERRUPTED OR ERROR FREE. AS LLC EXPRESSLY DISCLAIMS ANY WARRANTIES NOT STATED HEREIN.

10. NO LIABILITY FOR CONSEQUENTIAL DAMAGES. The entire liability of AS LLC and its licensors, distributors, and suppliers (including

its and their directors, officers, employees, and agents) is set forth above. To the maximum extent permitted by applicable law, in no event

shall AS LLC and its licensors, distributors, and suppliers (including its and their directors, officers, employees, and agents) be liable for

any damages, including, but not limited to, any special, direct, indirect, incidental, exemplary, or consequential damages, expenses, lost

profits, lost savings, business interruption, lost business information, or any other damages arising out of the use or inability to use the

Products, even if AS LLC or its licensors, distributors, and suppliers have been advised of the possibility of such damages. Customer

acknowledges that the applicable purchase price or license fee for the Products reflects this allocation of risk. Because some

states/jurisdictions do not allow the exclusion or limitation of liability for consequential or incidental damages, the above limitation may not

apply. If the foregoing limitation of liability is not enforceable because an AS LLC product sold or licensed to Customer is determined by a

court of competent jurisdiction in a final, non-appeasable judgment to be defective and to have directly caused bodily injury, death, or

property damage, in no event shall AS LLC's liability for property damage exceed the greater of $500 or fees paid for the specific product

that caused such damage.

11. WARNING: (1) AS LLC PRODUCTS ARE NOT DESIGNED WITH COMPONENTS AND TESTING FOR A LEVEL OF RELIABILITY

Amper Datalogger Family

Introduction

Automation Solutions Amper, milliAmper and microAmper provide a new, modern way to

electronically collect current and voltage data. Each device may be connected to a signal of

interest and the device will automatically take readings at a preset rate, saving the data to a

standard low cost SD/MMC data card. The data may then be transferred to a PC for further

analysis, either with standard PC programs such as Microsoft’s Excel or with the provided

ChartLogger program, which is capable of manipulating and displaying huge amounts of data. This

manual covers operation of three similar models, the Amper, milliAmper and microAmper. The

Amper is typically connected in series with a standard 5A current transformer. The milliAmper is

typically connected in series in a 4-20mA current loop. The microAmper, along with a resistor, may

measure directly applied Voltages or currents and with a non-contact clamp on current probe it

may log currents to thousands of Amps. With the exception of the input signal rating the units are

identical and only differ by the internal load resistor. They may be referred to below simply as the

Amper. Features include:

Easy to operate. There are no switches, knobs or buttons. One blue LED occasionally flashes

to indicate successful writes to the card, another red LED flashes if there’s an error, such as the

data card full. Pulling out the card allows the operator to walk away with logged data in

seconds.

Easy to install. There are just two wires to connect, insensitive to polarity. The unit can be

connected and running in minutes. The extremely low impedance (0.05 Ohm for 5A CT’s and

15 Ohm 0.3 Volt drop for the millAmper) allows it to run in series with many other devices in the

current chain.

Easy to configure. All configuration settings are done via simple text files written on the memory

card. Use the Amper configuration program (provided) to make any changes, insert the card

and the configuration is automatically set and retained; the Amper then automatically deletes

the configuration files. The Amper configuration program easily lets the user change settings

such as site name, acquisition rate, time and date, CT and scaling factors.

No external power required. The unit typically operates for 5 years with the user replaceable

high capacity battery. Since events of interest often occur just before or after power loss being

independent of external power is a huge benefit. As well as maintaining the time and date the

unit automatically measures its own battery voltage, and will start to write warning messages to

the data card typically 3 months before the battery fails.

Accurate data logging. The Amper, designed for 5 Amp CT’s, measures current surges up to 30

Amps at full scale A to D resolution to accurately capture events such as motor startups,

overloads, heavy load changes, line sags and surges. If the input current is below 6 amps the

signal is automatically routed through a separate input signal path so it is still acquired at the

full scale A to D resolution. This gives a total resolution exceeding 14 bits. The other models

have similar input scaling circuits. True RMS (including dc offset) data acquisition is used, so

the data is accurate no matter what shape the signal waveform is. Measurements from any type

of VSD, switchboard or non sinusoidal source are all accurately recorded. All data is saved to

the card in raw text format, so may be calibrated or offset if required after acquisition without

any loss of accuracy.

Amper Manual Version 2.01 Page 8 of 45

Fast data logging. The user may set the data acquisition rate, from 20 readings per second to

about one per hour; in 50mS increments. Adjustable hysteresis lets the logger accurately catch

high speed impulses without creating giant files.

Lots of data logging. The amount of data collected using the Amper may be huge. At the fastest

data acquisition rate over 1.7 million readings are taken every day. At this rate in less than an

hour files are too big to load into Microsoft Excel. (No problem for the ChartLogger program,

included with the Amper) However, the large size and low cost of SD/MMC cards provide deep

data storage. Using a 2 GByte card and taking samples twice a second a year’s worth of data

fits on a single card. Use a sample rate of once a minute and you won’t live long enough to see

the card full.

Compatible data logging. Every single reading collected by the Amper is stored as a plain

ASCII string in a text file, along with the date and time stamp of each reading. Every day a new

data file is created. Open any day’s file with any text editor such as notepad. View, zoom, scroll,

pan, print, see statistics and inspect the data with ChartLogger. (Excel may be used for small

files).

Pulse Capability. Change a couple of configuration files on the data card and the Amper is

reconfigured to become a powerful pulse logger; useful for utility, traffic, flow and similar

measurements. Collect pulse data (up to 10 pulses per second) in buckets of minutes to an

hour allowing for easy analysis of totals that are simply impossible to collect with a typical

totalizer type counters. Even copy data from the card while running without loosing any pulse

counts.

Unattended data logging. Leave the Amper running all the time; if there’s a problem swap the

card and look at the data. Just pull the Amper data every year or so (unless you need it

sooner), replace the battery every 5 years or so; that’s it. Forget changing the circular charts,

the dried up pens and weekly wind ups.
