DE-18 USER MANUAL SECTION 9
100
NOTE ON TRANSDUCERS: Whenever a sensor is
suspected of fault, the recommended cause of action
is to measure the signal (pressure, temperature, etc.)
with an alternate calibrated instrument and compare
readings. If readings conflict, the electrical and/or
tubing connections should be inspected, and if no
faults are evident, then replace the sensor and re-
evaluate against the calibrated instrument.
9.2 CALIBRATION
The controller has software calibration of the
pressure and temperature probes. Calibration is
required when a transmitter, transducer or a probe
has been changed. 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 difficult, room
temperature/open atmosphere calibration is
adequate. Calibration may only be done while
machine is stopped and unarmed.
To enter calibration mode, follow the directions in
Section 5: Controller on page 51 to access the "S"
code number system. To make adjustments,
Press the DOWN key or the UP key to scroll through
the variable.
