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
•
temperature probes "Pt100" complete with SICRAM module
•
direct 4 wire "Pt100" probes complete with TP47 module
•
2 or 4 wire "Pt1000" probes complete with TP47 module
NOTE: The probes fitted with SICRAM module 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 UNIT/MENU key again.

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 paragraph ‘Calibration of the combined
humidity/temperature probe’ at page 11.
