Thomson Technology
Use the INCREMENT or DECREMENT push-buttons to adjust the
correction factor number while observing the displayed battery voltage
level on the MEC 20. Adjust the correction factor number to obtain an
identical voltage reading as measured with the external DC voltmeter.
With the correct voltage displayed, press the
ENTER
push-button to
accept the correction factor number. Record the correction factor number
on the MEC 20 programming sheet for future reference if required.
10.6.8. ENGINE TEMPERATURE & OIL PRESSURE CALIBRATION
ENGINE TEMP
127 95 ºC
Displays the type of calibration function.
Displays the calibration correction factor number (0-255) used to obtain the
correct Temperature or Pressure reading.
Displays the actual temperature or pressure measurement that will be the
same value as shown on the MEC 20 display menus. This reading may be
calibrated higher or lower by changing the correction factor number.
10.6.9. TEMPERATURE CALIBRATION PROCEDURE
Before the equipment is put into final operating service, the engine temperature
analog circuit must be field calibrated to meet the performance accuracy as
specified, to ensure correct operation. The engine temperature analog circuit
must be calibrated with the engine temperature sender supplied with the controller
and mounted on the engine.
WARNING!!!
Failure to field calibrate and validate the correct operation
of the temperature analog circuit on the equipment may
result in severe equipment failure or damage.
To calibrate the MEC 20 temperature sensor, perform the following procedure:
