Calculation Of The Calibration Load; In Order To Adjust This Gain; Example Calculation Of Payload - Komatsu 930E-2 Shop Manual

In order to adjust this gain:

1. Start with the payload meter in normal operation
mode.
2. Adjust the gain pot, left to reduce the value and
right to increase the value.
3. Press and hold the LIGHT/INC and
MODE switches until "CHEC" is
flashing on the meter.
4. Press and hold the LIGHT/INC
switch until "ALL0" is flashing on
the display. "A.FUL" may also be displayed.
5. Press the LIGHT/INC switch14 times. The number
displayed will be the current Gt gain. This is not a
"live" reading. Any time the potentiometer is
changed, this cycle must be repeated to view the
change.
6. Press MODE once and "CHEC" will
flash on the display.
7. Press MODE once and the meter will return to
normal operation.
These calculations used a 13" front suspension diame-
ter and 10" rear suspension diameter.

1. Press and hold the LIGHT/INC and
MODE switches until "CHEC" is flash-
ing on the display.
2. Press and hold the CAL/CLR switch
until "CALL0" is flashing on the display.
