OM6010 Payload Meter II - Section 60 Page 60-9 Checking the Gain 1. Press and hold the LIGHT/INC and MODE switches until "CHEC" is flashing on the meter. Adjusting the Gain Before adjusting the gain perform the following steps: 1. Confirm the suspension oil and nitrogen charges are at the levels specified in the shop manual. 2. Press and hold the LIGHT/INC switch until "ALL0" is flashing on the display. "A.FUL" may also be dis- played. 2. Weigh the empty truck and then calibrate the payload meter. Do both in succession to ensure the weights are nearly identical. 3. Press the LIGHT/INC switch14 times. The num- ber displayed will be the current G t gain.
Press MODE twice to return to normal operation. 3. Weigh at least 10 different loads to get an accu- rate deviation from actual scale weight and the payload calculation from the payload meter. Complete the gain adjustment worksheet at the end of this module. The worksheet is an accu- rate way to calculate the necessary gain adjust- ment. Adjustment Procedure: 1. Ensure the PLM II™ is in normal operating mode. 2. Adjust the gain potentiometer on the side of the meter. Right to decrease, left to increase. 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 dis- played. 5. Press the LIGHT/INC switch14 times. The num- ber displayed will be the current G t gain. This is not a "live" reading. Any time the gain is changed, this cycle must be repeated to view the new change. 6. Press MODE once and "CHEC" will flash on the display. 7. Press MODE once and the meter will return to normal operation.
