Note: in the RHS mode, the software automatically compensates for the effect of temperature on
the humidity standard. No additional correction is required.
b)
Humidity or Temperature
: press the ENTER key to select. The LC display shows the value
read by the probe at the time the ENTER key was pressed. The word “humidity” or
“Temperature” is shown on the message line. Use the UP or the DOWN key to change the
humidity or temperature value to match the value of the reference environment. For a faster
change, keep the key pressed down. Press the ENTER key when done.
After pressing the ENTER key, the message “sure?” should appear on the LC display. Press
ENTER to confirm. Next, the LC display will confirm that the probe adjustment has been
successfully completed. At that time, press ENTER to exit or MENU to return to the function Adjust
M.PT and do another calibration point.
Carry on in the same manner for each calibration point, following the sequence described above.
Note: you can exit the function at any time (without calibrating the probe) by pressing the MENU
key.
7.4 ADJUST 1PT
Definition
The Adjust 1PT function permits to do a 1-point adjustment (offset adjustment) of a ROTRONIC
HygroClip digital probe against a known reference environment. This function is limited to a simple
offset adjustment that is applied across the entire measuring range.
To prevent unauthorized or
accidental changes, lock the keypad (software configuration) to block out access to this function
either from the keypad or from the HygroPalm calibrator.
Warning: a 1-point adjustment is no substitute for an adjustment at 2 or more points. Adjusting the
probe at only one value can improve accuracy over a narrow range of conditions and may also be
detrimental to accuracy at other conditions.
Selections
The Adjust 1PT function offers the following choices:
RHS
:
Humidity calibration using the ROTRONIC Humidity Standards
1)
Humidity
:
Humidity calibration using any suitable reference environment
Temperature
: Temperature calibration using any suitable reference environment
1) For humidity calibration, ROTRONIC offers convenient, certified humidity standards that generate known
humidity values (for more details, see Appendix 3 - Humidity Calibration).
Procedure
When two probes are connected to the transmitter, be sure to select on the display the HygroClip
probe to be calibrated prior to entering the function.
