NOTE ON TRANSDUCERS:
Whenever a sensor is suspected of fault, the rec-
ommended cause of action is to measure the signal
(pressure, temperature, etc.) with an alternate cali-
brated instrument and compare readings. If read-
ings conflict, the electrical and/or tubing connec-
tions should be inspected, and if no faults are evi-
dent, then replace the sensor and re-evaluate
against the calibrated instrument.

7.13 CALIBRATION

The Supervisor II has software calibration of the
pressure and temperature probes. This calibration
affects the offset but not the slope of the pressure
and temperature calculations. Because of this, the
most accurate method is to heat or pressurize the
transducer to its operating value. If this is too diffi-
cult, room temperature/open atmosphere calibra-
tion is adequate. Calibration may only be done
while machine is stopped and unarmed.
To enter calibration mode, you must press the fol-
lowing keys in sequence while in the default status
display mode: "

REMEDY
Drain and change fluid.
Remove the water vapor from compressed
air prior to distribution through the air system.
Check operation of aftercooler and moisture
separator. Install a compressed air dryer
sized for the flow and dryness level required.
(Note: Filters may also be required to remove
particulates, liquid oil aerosols or for oil vapor
removal. Change cartridges as recommend-
ed by the filter manufacturer).
drain traps routinely to insure their proper
operation. Maintain them regularly.

screen like the following:
In the above example, "0" refers to the amount of
adjustment (in psi or ºF, "97" refers to the current
value of P1).
To make adjustments, Press the "

increase or decrease always showing the total
amount of adjustment. Maximum adjustment is + 7.

sures may be calibrated individually.
