• If these reading are still not within 1 kPa of each other then further adjustment may be
undertaken by modifying the TTT.T value.
• The theoretical pressure reading (TTT.T) and actual chamber temperature reading
(CCC.C) are directly related and when the actual temperature value is increased or
decreased, the theoretical pressure value will also increase or decrease respectively.
• Adjust the theoretical chamber pressure (TTT.T) and actual chamber temperature
readings (CCC.C) as follows:
• Press the Rubber and Plastics key.
•
The Po value will now SToP flashing and the Co value will now flash.
• Use the wrapped and unwrapped keys to correct the TTT.T value so that it is
within 1 kPa of PPP.P.

– now
re-check
the actual temperature reading (CCC.C) with the
reading on the temperature reference meter. The readings need to be stable, so allow
sufficient time to compare them.
• If you are confident that the temperature readings are still within ±0.25°C, then the unit
is in equilibrium and the calibration has finished.
• If the readings are outside of the ± 0.25°C tolerance then further diagnostics may be
required prior to re-calibration.
16. Press the
SToP
button on the control box when finished.
2. Switch off the unit and remove all calibration equipment.
