3. THE PROGRAMMING MENU
To access to the menu press simultaneously the following keys:
The items to be set are listed in this order:
1. Probe type: the "PRBE_TYPE" message is displayed in the comment line. The main line
in the center of the display shows the type of probe connected to the instrument. The
following probes can be connected to the input:
• humidity/temperature combined probes with "Pt100" sensor complete with SICRAM
module
• humidity/temperature combined probes with "thermocouple K" sensor complete with
SICRAM module
• temperature probes "Pt100" complete with SICRAM module
• direct 4 wire "Pt100" probes complete with TP47 module
• 2 wire "Pt1000" probes complete with TP47 module
NOTE: The probes fitted with SICRAM module, and Delta Ohm "Pt1000" probes, are
automatically detected by the instrument upon turning on. The type of probe is
configured by the instrument and cannot be modified by the user.
If the direct 4 wire "Pt100" probes and the "Pt1000" probes that are not manufactured by
Delta Ohm are connected to the instrument, the NO_PRBE_SER_NUM message is
displayed. In this case the probe type must be entered manually by the user:
- use the and arrows (respectively located above the HOLD and REL keys) to
modify the type of probe;
- press DATA/ENTER to confirm the modification and go onto the next item;
- press CLR/ESC to cancel the modification;
- to exit the menu, press the MENU key again.
2. User calibration procedure of the combined humidity/temperature probe: the probes
are calibrated in our laboratory at 23°C at the relative humidity points of 75%RH, 33%RH
and 11.4%RH. On request, the probes can be checked at different isotherms.
For the Calibration sequence, see chapter 4.1.2, paragraph "Calibration of the combined
humidity/temperature probe".
