The stored calibration values of the 8 humidity reference points can be
deleted at any time, but the following points must be considered:
– The calibration values of all the humidity reference points must be delet-
ed before a newly inserted sensor is calibrated.
Note: If the calibration values of all the humidity reference points are
deleted, a measurement of any accuracy cannot be guaranteed until at
least the basic calibration has been carried out (see chapter 5.3.3).
– Calibration values of individual humidity reference points must be
deleted if the reference point can no longer be recalibrated because of
a missing humidity standard. The measuring instrument automatically
calculates a mean value from the remaining calibrated points for the
deleted one.
Note: The measuring instrument should always be calibrated at at least
2 humidity reference points!
• Activate the menu mode and select main menu point "05".
• Call the submenu by pressing <Enter>. You may select the individual
submenu points by pressing the < > oder < > key.
– You may delete the calibration values of all the humidity refer-
ence points simultaneously in the first menu point. The values are
set to --.- %RH.
– You may delete the calibration values of the individual humidity
reference points (4, 6, 11, 33, 53, 75, 90 and 98) in menu points
2 to 9.
• The corresponding calibration values are deleted by selecting "YES" in
the appropriate menu point. The deletion is confirmed in the display.
The two analogue outputs on the back of the instrument supply a voltage
signal proportional to the measured value:
– Humidity: 0.0...10.0 VDC equivalent to 0.000...1.000aw
min. load resistance 10 kΩ
– Temperature: 0.0...10.0 VDC equivalent to 0...+50°C
min. load resistance 10 kΩ
Note: The measured value range assigned to the analogue output
signal (0...10 VDC) may be established individually.
– Humidity: from 0.000 to 1.000 aw in steps of 0.001aw
– Temperature: from –20 to +100°C in steps of 0.1 °C
The lower limit value (LO) is in this case equal to 0 VDC, and the upper
limit value (HI) 10 VDC. The signal is linear throughout the range.
