ATTENTION:
To extend the life of your digital scale, do not drop items to be weighed onto the
platform or overload the scale beyond its rated capacity. Shock-loading and
overloading may damage the load cell and void the warranty.

Introduction
The SB-30/70/150 Digital Bench Scales are
compact bench scales with display and five
function keyboard. It is available in 30 lb (15
kg), 70 lb (30 kg) and 150 lb (70 kg) capaci-
ties. It comes standard with a bright LED
screen for easy readout, a removable stain-
less steel platform, and an RS-232C serial
communication port.
These scales can be configured to display
their divisions in two separate modes – non-
NTEP mode and NTEP mode. The scale is
shipped from the factory configured in NTEP
mode. The NTEP mode is supplied for
scales which need to comply with Handbook
44 requirements. To re-configure the scale,
please refer to the “Setup Menu Mode” sec-
tion of the manual.
SB-30/70/150 use full duplex RS-232C serial
format for communication with personal
computers or remote displays. Units can
transmit data on demand or continuously in
several popular data protocols.
Each scale’s serial communication parame-
ters are altered through the User menu The
“User Menu Mode” section of the manual
explains how to use the five front panel keys
to maneuver and save settings in this menu.

Installation and Wiring
The scale’s back panel comes equipped with
a female DSUB-9 connector for the RS-232
serial port, a jack for DC power input, a cali-
bration switch, a remote display connector
(SB-30 & SB-70 only) and an ON/OFF rocker
switch. To install the scale, simply plug the
enclosed AC Wall Adapter into the scale’s DC
power jack first, then into an AC outlet (115
VAC only). For SB-30 and SB-70 scales, plug
in the remote display/keyboard unit. Finally,
turn the rocker switch to the ON (“1”) position.
The scale is now ready for use.

The scale can be calibrated by following the procedure shown below. The minimum test weight
and the recommended test weight depends on the scale’s capacity.
For the SB-30, the minimum test weight is 0.3 lb (0.15 kg) , and the recommended test weight is
20 lb (10 kg). For the SB-70, the minimum test weight is 0.7 lb (0.35 kg) , and the recommended
test weight is 47 lb (23 kg). For the SB-150, the minimum test weight is 1.5 lb (0.7 kg) , and the
recommended test weight is 100 lb (50 kg).

Calibration / Continued
To calibrate the scale:
1. If you are already in Setup Menu Mode, scroll to “F 12” and press the ZERO key. Otherwise,
turn the scale off and set the Calibration Switch on the back panel to the opposite 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 other electronics to become
thermally stable.
2. Press
ZERO to zero the value, then press the NET/GROSS key to save the zero point value.
3. 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.
4. 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.
5. After setting the exact value, press the NET/GROSS key to save the value.
6. If the calibration was successful, the display will show "ECAL" momentarily, then freeze. Exit
the Calibration mode and enter the Normal Operating Mode by positioning the Calibration
Switch back to its original position.
7. If the calibration was not successful, one of the error messages below will appear. Take the
indicated 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 1% 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.
To place the unit back into the Normal Operating mode:
1. Toggle the Calibration Switch back to its original position.
2. The display will go through a digit check, then settle into Normal Operating mode. All front
panel keys will now return to their normal mode of operation.

APPENDIX B: Troubleshooting the Serial Port
The scale’s serial port operation can be verified by following the procedure below. This procedure
makes use of HyperTerminal - a serial port communication program bundled with Windows 95
and Windows 98 operating systems. A HyperTerminal configuration file is available on the Tran-
scell website.
A comprehensive summary of the various Serial Data Formats (SDF’s) can be found in the SB
Series Service Manual.
To test the scale’s serial port for proper operation:
1. Connect the NMC-1 Null Modem Cable or equivalent between the scale and your PC. Make
sure to note which communication port (i.e. COM1, COM2) you are using on the PC.
2. On the scale, select the desired setting in the User Menu, including baud rate (A1), Data Bits
and Parity (A2), mode (A3), and serial data format (A4). Note that all Transcell scales have a
fixed parameter of one (1) stop bit.
3. On your PC, run HyperTerminal. Select the proper settings for the following using the scale’s
settings:
Baud Rate
Data Bits
Parity
Stop Bits = 1
4. Enable the CAPS LOCK key on your PC.
5. This test verifies that the scale is transmitting properly. If the scale is set to Demand mode,
pressing the PRINT key on the scale should echo the weight readout on the PC screen. If the
Continuous mode has been selected on the scale, the PC screen will overrun with weight in-
formation.
NOTE: The TOLEDO, A&D/NCI/CAS, FAIRBANKS and TRINER formats do not support a Con-
tinuous mode.
6. This test verifies that the scale is receiving properly. Use the table below to determine the
valid commands for your serial data format setting. For example the ‘P’ command is exe-
cuted by pressing the capital “P” key on your PC keyboard. Unless otherwise specified, you
do not need to press the ENTER key on your PC.
NOTE1: If the scale is set to Continuous mode, the print commands will be ignored.
NOTE2: If the scale is in motion, the print commands will be ignored for most SDF’s.

problem. Otherwise, possible load cell damage due to
overloading.

on the platter. Remove the weight and then press the ZERO
key if necessary. Try re-calibrating the scale if this doesn’t
solve the problem. Otherwise, possible load cell damage
due to overloading.
– LO – Warmup Mode The scale has been turned on without the platter installed.
Install the platter and then press the ZERO key if neces-

scale’s capacity. Use a smaller test weight or re-adjust
value.
