I. GENERAL DESCRIPTION

The Cal 2000 is a battery-powered, portable electrochemical

gas generator designed to calibrate toxic gas sensors. Fast

warm-up time allows the instrument to be turned off between

remotely located sensors saving battery life and avoiding gen-

eration of unwanted gas. A built-in mass flow sensor provides

accurate flow control and the ability to measure externally pro-

vided sample draw flow rates. The Cal 2000 uses the follow-

ing components to produce the calibration gas/air mixture:

Internal Micro Pump

A small, rotary vane, micro air pump draws in ambient air to

blend with the generated gas. The pump may be disabled for

use in calibrating sample draw instruments.

Electrochemical Generating Cell

The electrochemical generating cell contains an electrolyte

solution and either inert or consumable electrodes, depend-

ing upon the gas being generated. A precise concentration of

gasis produced when a known amount ofcurrent anda known

amount of air is supplied continuously to the cell. Each cell

has a built-in memory chip that tells the Cal 2000 instrument

what type and range of gas can be generated and how much

cell life is remaining. The electronics board mounted to the

cell should never be removed from the cell. Removal of this

board will void warranty and destroy the cell. Due to the de-

sign characterization of the cell, the unit must be oriented flat

(on the units feet) for correct concentration output.

Cell Installation and Removal

There are no tools required by the end user for ser-

vice of the instrument. The electrochemical cells

are shipped seperate of the unit and should be in-

stalled on receipt. To install the cell, remove the bottom

cover of the instrument. This is done by pulling each of the

‘plunger feet’ on the bottom of the instrument. Once all of

the plungers have been pulled out, the bottom cover is sim-

ply removed from the instrument.

The cell is keyed to ensure proper alignment into the in-

strument. When installed, the circuit board of the cell should

be flat with the bottom of the instrument. Push up on the

clear window at the back of the instrument to eject the cell.

A set of four fully charged, heavy duty alkaline "C" batteries

provides 20-30 hours of operation at .5 LPM. Note: Re-

chargeable or light duty batteries can be used, but they

give significantly less operating time.

Microprocessor-Based Circuitry

The Cal 2000 has microproccessor based circuitry that per-

forms several different operations and offers the user many

different features. The microprocessor tracks cell and battery

usage,monitors the airflow rateand controls thecell andpump

to give the selected ppm and flow rate. In addition to English,

everyCal2000 is capableofprovidingmenu displays inFrench,

German and Spanish. See section IV. Menu Options for in-

structions on how to change the menu language.

Digital Display

The Cal 2000 has a liquid crystal display (LCD) located on the

front of the instrument. This display is protected by a thin,

clear plastic cover that is part of the front label and may be

replaced if it becomes scratched or unclear.

POWER and SELECT

The POWER and SELECT switches are momentary push but-

tontype switchesactivated throughthe front membrane panel.

They are physical switches mounted directly on the circuit

board.

Nylon Carrying Case

The Cal 2000 comes with a convenient, durable, nylon carry-

ing case. It is adjustable to be worn as a hip pack, or the belt

strap can be reattached to be worn around the neck or over

the shoulder. The top of the carrying case is clear plastic,

allowing the unit to be operated while within the case, and

thereis aconvenient front pocket for storage of additionalcells

or the delivery hose. Page 4Page 19

Page 5 Page 18

Delivery Hose

The instrument comes standard with a three (3) foot long,

¼inch diameter norprene hose for delivering the gas to the

sensor or calibration adapter. The hose has a male quick

connect adapter for easy attachment to the instrument.

Mass Flow Sensor

The Cal 2000 has a built-in mass flow sensor that measures

the flow rate of the instrument. This information is used in two

ways. With the pump engaged, it is used to control the pump

to the desired flow rate over a range of 0.2 to 1.0 LPM. With

thepump disabled, it is used to measurethe airflow ratedrawn

through the Cal 2000 by an external pump. This information

is used to adjust the cell current to the desired ppm. The flow

meter should be calibrated against a primary mass flow stan-

dard every 12 to 24 months.

Internal Charcoal Filter

An internal charcoal filter is provided to scrub contaminated

air and provide a clean baseline for “zeroing” sensors. This

filter should be replaced on a yearly basis and is removed

by pulling out the grey plunger at the top of the unit. Spare

filter elements can be purchased through ACD. Note: The

charcoal filter must be fully installed into the instrument for

correct operation.

"Cell Failure!" accompanied by an audible beep.

There are two possible causes for a cell failure. One

cause is that the instrument has not detected a cell. The

other is that a high voltage has been detected across the

cell.

If the cell is not initially detected by the processor, the unit

will display cell failure and immediatly shut down (without

entering ‘purge mode’). This failure can happen either

because a cell is not inserted, connection to the cell is not

made, or due to a failure of the circuit board on the generat-

ing cell.

The cell failure alarm will also engage if the microproces-

sor detects an abnormally high cell voltage condition. One

possibility for this high voltage is that one of the pins may

be making a faulty electrical connection. Another possibility

is that the electrolyte level is too low. For instructions on

how to replenish the electrolyte refer to

Section V: Maintenance.

If this message continues after the cell has been plugged

in correctly and the electrolyte level has been confirmed to

be sufficient, contact the factory and/or replace the cell.

"Cell is used up! “ accompanied by an audible beep.

The cell life has expired and the display will show 0% cell

life remaining. Replace the cell.

"Battery is low!" accompanied by an audible beep.

If battery power drops below 5% capacity, the screen will

flash "Battery is low!". Replace the batteries or switch to AC

power.

Page 6Page 17

Optional items available for the Cal 2000 include:

AC Adapter

The Cal 2000 may also be operated from an AC adapter.

The AC adapter converts the AC voltage supplied from the

main power lines to 6 VDC which is used in lieu of the bat-

teries. The adapter plugs into the instrument from the un-

derside of the case directly into the power board and is in-

dependent of polarity. If needed, contact the factory for

exact specifications of the AC adapter.

Hard Body Instrument Case

A water resistant, padded instrument case is available for

storage and shipping of the Cal 2000. The case is made

out of rugged, high impact resistant plastic and will help pro-

tect the instrument in harsh environments. The foam insert

may be customized to hold additional items like spare bat-

teries and cells.

Extension Hoses

Longer sample hoses may be purchased for use with the

Cal 2000 in lengths up to 20 feet. Note: the internal pump

may not be capable of overcomming flow restricions asso-

ciatedwithextreme hoselengthswhen operatingat1.0 LPM.

Troubleshooting

No Power To Instrument

There are two common causes for the unit to not power

up when the POWER switch is pressed for three sec-

onds.

The most common is that the batteries are dead. Try

replacing the batteries with new alkaline batteries or try

powering the unit from the AC power adapater.

The second most frequent cause for no power to the

instrument is a blown protective fuse. This fuse can be

shorted out if the batteries have been removed from

the instrument with a metallic object such as a

screwdriver. If the protective fuse has been blown

contact the factory.

"Flow too low" / "Flow too high" accompanied by an

audible beep.

Accurate air flow is critical to an accurate gas mixture.

The microprocessor and built-in precision mass flow

sensor continuously monitor the air flow. If, however, a

flow problem develops (e.g. air blockage or kinked tubing)

which cannot be corrected within ten seconds, the unit will

display "Flow too low." If the problem cannot be cleared

after an additional minute, the instrument will enter the

purge mode and then power down.

If the pump was not disabled prior to attaching an external

pump device, or the sample draw flow rate is greater than

5.0 LPM, the unit will display "Flow too high." If the

problem is not cleared within one minute, the instrument

will enter purge mode as above.

located in the middle left front of the instrument, until the

display reads A. C. D., approximately three (3) seconds.

Release the switch immediately thereafter.

The instrument will sequence through several screens as

follows:

Please Note: If you would like to change the language of

the menus, see section IV. Menu Options: Foreign

Language Option, for instructions.

V. Maintenance

The electrochemical cells of the CAL 2000 require periodic

maintenance to provide optimum performance. It is

recomended that the electrolyte solution be replaced on an

annual basis for most gases generated by the CAL 2000.

The exception to this is the ClO2 electrolyte. Please refer to

the instructions enclosed with every chlorine dioxide cell or

replacement electrolyte pack.

If the instrument is returned with the cell on an annual basis

to maintain NIST certification, the electrolyte will be replaced

bythe factory.

The following steps should be taken to replace electrolyte.

........a. Remove cell as described in section I. General

Description: Cell Installation and Removal.

........b. Unscrew solid fill plugs on reservoir and

remove liquid.

........c. Use syringe (provided with electrolyte) to add

liquid to within 1/8 inch from the bottom of fill hole.

Warning: Do not over-fill reservoir. Trapped air must be

allowed to escape through vent plug as fill screw is

replaced. Contact the factory for more information.

........d. Replace fill plugs.

Caution

Both the electrochemical cell and the alkaline batteries used

in the CAL 2000 instrument contain corrosive chemicals. In

addition, depending on the type of cell being used, the gas

being generated can be corrosive. The design of the

instrument takes this into consideration, and the 300

second purge cycle allows the corrosive gases to be swept

out of the instrument. It is important not to remove the

generating cell before this purge cycle is completed. While it

is not expected that the chemicals in the cell or alkaline

batteries will leak during normal operation, it is recom-

mended that both the generating cell and the alkaline

batteries be removed from the instrument if it is being stored

for periods longer than one week between use.

The Calibration Date refers to when the instrument itself

was last calibrated at the Factory. It does not refer to the

calibration date of the generating cells, which are field

replaceable.

The following status screens indicate the remaining cell life

and battery status.

Please Note: If you have a ClO2 or H2S cell in the unit you

will recieve an additional message at this time. Please

refer to section IV. Menu Options for additional informa-

tion.

When the air flow rate screen appears,

you may adjust your flow rate by pressing the SELECT

switch. If you do, you will enter the flow adjust screen.

H2S Quick Select Option

After the Battery Status screen appears during the start up of

the instrument, if a H2S cell is in the instrument, a message

will appear offering the option of changing to Quick Select

mode.

You can switch to the quick select mode by pressing the

SELECT switch. If you do you will enter the Quick Select

choice screen.

You can turn the Quick Select mode off by pressing the

POWER switch (arrow up) or you can turn it on by pressing

the SELECT switch (arrow down).

At any time during the operation of the unit or during the stabi-

lization period you can enter the menu to change the Quick

Select mode by pressing the SELECT switch (arrow down).

It is important to note that when you enter the Quick Select

mode for the H2S cell, you cannot change the flow rate of the

instrument. The Cal 2000 instrument will automatically vary

the flow rate to acheive the different ppm concentrations of

H2S.

Once you have entered the Quick Select mode for the Cal

2000, you can only adjust the ppm concentration in fixed 10

ppm increments, between 20 ppm and 100 ppm.
