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.

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.

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.
