• How to set the range of the pressure probes
If an instrument with the following part number is used: XC645CX – xxxxF, it is pre-set to work with pressure probe with the
following range:
Probe 1: -0.5 –11.0 bar (relative pressure);
Probe 2: 0–30.0 bar (relative pressure)
If the probes you're using have a different range act as in the following:
To set the pressure range of the Probe 1 (suction probe) use the parameter:
PA04: Adjustment of read out corresponding to 4mA
PA20: Adjustment of read out corresponding to 20mA
Practically these parameters have to be set with the start and end scale of the probe range.
How to do:
1. Enter the Programming mode by pressing the Set and DOWN key for 3s.
2. Select the "Pr2" parameter. Then enter the password 3 2 1 0.
3. Select the PA04, adjustment of read out corresponding to 4mA, parameter.
4. Press the "SET" key: the value of the parameter will start blinking.
5. Set the lower value of the probe range.
6. Push the SET key to confirm the value. The PA20: adjustment of read out corresponding to 20mA parameter will be displayed.
7. Set the higher value of the range.
8. Push the SET key to confirm the value. Next parameter will be displayed.
Do the same things for the Probe 2, FA04, FA20 parameters.
