WEIGHING ERRORS
Over-Capacity Limit (OVRCAP)
The display shows the message "OVRCAP" if the weight on the scale
system exceeds the capacity limit. The capacity value is entered in
SETUP to warn of overloading the scale system.
Over Range (+RANGE)
The display shows the message "+RANGE" if the weight on the scale
system exceeds the maximum weight measurable by the scale system.
The over range value is always the system’s maximum A/D counts
multiplied by the scaling factor. The actual weight at which over range
occurs depends on the calibration, zero, and display count size.
Under Range (-RANGE)
The display shows the message "-RANGE" if the weight on the scale
system is less than the minimum weight measurable by the scale system.
The under range value is always the system’s minimum A/D counts
multiplied by the scaling factor. The actual weight at which under range
occurs will depend on the; calibration, zero, and display count size.
Low Battery Indication (LO BAT)
If the supply voltage drops below the (10.5 Volts), the message “RECHARGE
BATTERY - TURNING OFF” and “LO BAT” will periodically show on the display to
alert the operator of the low battery condition.

SHORT FORM CALIBRATION
The Short Form Setup & Calibration procedure allows you to change
“SETUP” and “CAL” numbers of indicator. Setup and calibration numbers
are displayed during self-test.
Do not attempt to calibrate scale if indicator is not reading stable weights.

CALIBRATION NUMBER
The “CAL” number is adjusted to make scale read proper weight for
different load cells and to make accuracy adjustments on a scale system.
Systems should be checked with known weights and adjusted if necessary
to insure accuracy. Both setup and calibration numbers are changed to
convert a scale from lbs to kgs.
CALIBRATING SCALE FOR
MAXIMUM ACCURACY
Write down current SETUP and
CAL numbers of your GT 400
indicator. These numbers are
displayed during Self Test.

Note: To accurately calibrate scale,
you need a large amount of weight
that has a known value. For best
results you should have at least as
much weight as largest load you
plan to weigh.

POWER CONNECTION
Power can be obtained directly from a 12VDC battery or from a 120V or
220V AC power cube that plugs into a wall outlet. Attach power cable to
POWER connector located on bottom panel of scale.
Connect RED wire from power cable to +12VDC and BLACK wire to
GROUND. The indicator is fused internally at two amps.

INDICATOR CALIBRATION
If you connect an indicator to a different weighing implement, the
calibration and setup number may need to change. Refer to calibration
procedures (page 15-17) or contact your Digi-Star representative for
assistance.
Lightning Protection
Stationary systems use “Lightning-Protected” J-boxes and ground to
protect scale when lightning strikes nearby. Please call your Digi-Star
representative to request instructions F3050.
