Display
Controls
ON / OFF
Press and hold the power button to apply power to the weighing system electronics.
Hold button until the display responds (approximately 1 second). When power is
applied, the weighing system performs a self-test of the pad and the internal
electronics. When the self-test has been completed, the system begins weighing. If a
problem is detected during self-test, an error message will be displayed. Press the
button to turn the scale off.
NOTE:
When the scale is turned off using the ON/OFF button, it cannot be turned on
with the IR remote or RFX wireless indicator. If the scale is powered up using a
remote, turn off the scale with the IR remote or wireless indicator.
ACCUM / TOTAL
The scale will not accumulate when the weight is negative, zero or if the weight is in
motion (when Motion Detect is enabled). A display message "." with error icon will
be displayed if any of those conditions are present. After a successful accumulation the
scale must return to zero before the next weight can be accumulated. Failure to do so
will generate and display an error message: ".".

MODE
The Mode button cycles through the scale set-up menu (Mode Menu) when in normal
run mode. When in calibration mode, use the button to toggle through the calibration
menu. Refer the "Mode Menu" and "Calibration Menu" sections for further details.
ZERO
The ZERO button is used to display a zero weight when the scale shows a non-zero
value with no weight on the hook. If ZERO is pressed with weight on the hook, the
weight becomes the zero condition for the scale. This can be useful to cancel the
weight of any weighing fixtures, such as containers, chains or cables. When the weight
is removed, a negative weight shows until the system is zeroed again. If "Motion Detect"
(see Calibration Menu) is enabled, the "ZERO" command will be rejected when a
change in weight is detected. The weight must be allowed to stabilize before the zero
command is accepted.
NOTE:
The scale has a feature called Auto Zero Tracking (AZT) that corrects slight
zero changes during normal operation. If small weights are added slowly, the
scale will zero them off.
Lb/Kg
The Lb/Kg button toggles the weighing system between pound (English) and kilogram
(SI metric) units of measure. The current unit of measure is shown in the top left of the
indicator screen.
TARE
Pressing the TARE button will set the TARE equal to the current gross weight of the
total load suspended on the scale and then switch the display to net weight. The NET
indicator light is located below the indicator screen. The net weight is equal to the gross
weight minus the TARE weight. If TARE is pressed when a TARE is already set, the
display will briefly show the current TARE weight before returning to net weight display.
The TARE weight can only be set if the current gross weight is positive.
Clearing the TARE:
Press both the TARE and ZERO buttons to reset the TARE
to zero and return the scale to the GROSS weighing status.

Scoreboard
The output of the CS750 can be connected to a scoreboard to display continuous, real-
time information.
The signal is transmitted through the Serial I/O connector located on the side of the
unit. The connector has the following pinout:
Signal
Pin
TXD
F
GND
B
The transmitted signal has the following characteristics:
Fixed 8 Data bits, no parity, 1 stop bit.
Baud rate is configurable with the "printer baud rate" setting in the "Mode Menu".
The output swings from -9 VDC to 9 VDC.
The scoreboard output is an externally available signal designed to drive a numeric
overhead display such as the Intercomp LED Display or a computer RS-232 input.
Continuous Print Mode Transmitted Data: xxxxxxx<cr><lf>
Transmitted data is displayed in either NET or GROSS weight, whichever is currently
shown on the Wireless CS750 display. Data is transmitted at a rate of once per a
second. However, the transmission may be delayed when motion is detected.
The xxxxxxx field will vary in size depending on the length of the number. The field may
also contain a decimal point and/or a minus sign.
The connection to a 9-pin PC communication port is referenced in the following table.
