Introduction

The SP Series Digital Bench Scale is a

compact, legal for trade scale with remote digital

indicator. Housed in a standard black polymer

case, the indicator displays its numerals on a

bright VFD screen. The base unit features a

removable stainless steel platform, an RS-232

serial communication port, and adjustable feet

for leveling.

The SP Series uses full duplex RS-232 serial

format for communication with many types of

attached support equipment. The unit can trans-

mit data on demand, or continuously in several

popular data protocols to match a wide variety of

printers, remote displays, or personal computers.

If you plan to use your scale with equipment

other than a PC, you may have to alter the serial

communication parameters which are embed-

ded in the User Menu.

The User Menu is accessed through the front

panel keys. Complete directions, including a

graphical road map, are found in the Configura-

tion section of the manual.



Installation and Wiring



Unless you wish to interface to a device other

than a PC, no wiring is necessary. Simply con-

nect the indicator to the scale platform, plug in

the AC adapter, and turn the unit on. If the swivel

indicator option was ordered, the stainless steel

post may be mounted to the bottom of the base

with the hardware provided. Alternately, it may

be mounted to a table or bench. In general,

please allow a 20 minute warm up period before

using the scale.

If interfacing to a PC, simply connect the optional

null modem cable to a serial port (e.g. COM 1)

on your PC. If your computer has a 25-pin serial

port, a standard 9-pin to 25-pin adapter, such as

the type used for a mouse, may be used and is

readily available at your local computer supply

retailer.



If interfacing to a serial device other than a PC, you may have to wire

your own cable to communicate with that device. If so, refer to the 9-

pin connector pinout shown at right.

Configuration



All Serial Communication parameters are em-

bedded in a user menu consisting of 5 separate

menu selections, each with its own sub-menu of

choices. If your scale is connected by RS-232

serial communication lines to other equipment,

or you wish to disable the lb/kg key, you may

have to modify some or all of these parame-

ters. To modify these parameters, you must first

enter the USER MENU mode. Once there, four

of the front panel keys become directional navi-

gators to move around in the menus, and one

key is used to save or SET the selections. Com-

plete directions are found below.

ments.

NAME/CODE DESCRIPTION CODE/VALUE

Calibration

All SP Series scales may be calibrated with any precision test weight from 10 lb to 100 lb. The recom-

mended test weight is about 2/3 of the full scale capacity, but in general, the larger the test weight, the

more accurate the scale will be. The only restriction is thatthe test weight must be in pounds.

To calibrate the scale:



Turn the scale off. Locate the hidden switch on the base panel and set it at the rightmost position.

Turn the unit back on. The message "C 0" appears on the display briefly, followed by a value which

remains on the screen. Allow a 20 minute warm-up period for the load cell and indicator to become

thermally stable.



Press ZERO to zero the value, then press the NET/GROSS key to save the zero point value.



The display will momentarily prompt "C 1" for the span calibration, followed by "0.00" with one digit

flashing. Place the test weight on the platform.



Use the four directional keys to adjust the displayed value to the actual test weight value in pounds.

Increase the flashing digit by pressing the lb/kg key. Decrease the flashing digit by pressing the

ZERO key. The position of the flashing digit may be changed by pressing the PRINT key or the

TARE key.



After setting the exact value, press the NET/GROSS key to save the value.



If the calibration was successful, the display will show "ECAL" momentarily, then freeze. Exit the

Calibration mode and enter the Normal Operating Mode by turning off the scale, positioning the

calibration switch back to the leftmost position, and turning the scale back on.



If the calibration was not successful,one of the error messages below will appear. Take the indi-

cated action to correct the problem, then perform a new calibration.

"Err0" - The calibration test weight or the adjusted keyed-in weight is larger than full scale. Change

the calibration test weight or check the keyed-in weight.

"Err1" - The calibration test weight or the adjusted keyed-in weight is smaller than 10% of full scale.

Change the calibration test weight or check the keyed-in weight.

"Err2" - Check keyed-in weight with the actual weight placed on platform.
