Use the Calibrate 2 screen to adjust the calibration
value of the air and fluid. (Default value is 1000 mV.)
Calibrate the air and fluid:
• When the actual air or fluid pressure does not
match the target value on the Home screen and it
seems like it should.
.
For example, when air is applied to the system and
the system is in Standby mode, both target and
actual values should be 0.
• After replacing the electro/pneumatic regulator
(V2P) (415).
• After replacing the V2P cable.
Follow the steps in

1.
With the bleed resistor (24) removed from the
system, measure the resistance across the bleed
resistor. See
Check the Bleed Resistor, page 73
.
2.
Use the keypad to enter the measured value.
Only values between 9,000 and 11,000 Mohm
are allowable.
3.
Reinstall the bleed resistor into the system.
4.
Reattach the wire from the fluid pressure
regulator (21) to the bleed resistor (24) and the
bleed resistor to the ground rod (18).
5.
Make sure the wire coming out of the top of the
bleed resistor is plugged back into the kV board
(428) inside the electronics control panel.
6.
After the reassembly is complete, check the
continuity between the fluid pressure regulator,
bleed resistor, and ground rod.
