Optional Equipment - Section 6 OM6007 2/99 Page 6-8 Payload Meter II In order to adjust this gain: 1. Start with the payload meter in normal operation mode. Calculation of the Calibration Load This procedure is similar to the manual calculation of load. This calibration load is used as item #13 from the manual calculation procedure. 2. Adjust the gain pot, left to reduce the value and right to increase the value. 1. Press and hold the LIGHT/INC and MODE switches until "CHEC" is flashing on the display. 3. Press and hold the LIGHT/INC and MODE switches until "CHEC" is flashing on the meter. 2. Press and hold the CAL/CLR switch until "CALL0" is flashing on the display. 4.
Press and hold the LIGHT/INC switch until "ALL0" is flashing on the display. "A.FUL" may also be displayed. 3. Press the CAL/CLR switch to cycle through the following data. The sequence repeats. 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.
Sprung Weight = π 4 Suspension Diameter2 (Psi Left + Psi Right) Sprung Weight = Axle Weight(lbs)/2000 Example Calculation of Payload 4. Press MODE once and "CHEC" will flash on the display. 5. Press MODE once and the meter will return to normal operation. Figure 6-5. Item and Description Units 1. Year of Calibration Last 2 digits of year 2. Month:Day of Calibration XX:XX 3.
