o Humi Adjust: the HP23 displays both the current humidity read by the device to be calibrated and
the reference humidity (known environment). Press ENTER to activate the reference value menu
item and use the UP or DOWN arrow key to change each digit. Press ENTER to move the cursor to
the right. When done, press ENTER to save the value. Use the DOWN arrow key to select
. Press ENTER to activate the Acquire function. Press ENTER to confirm and save the
calibration point to the device memory. The HP23 automatically exits the menu.
o Temp Adjust: the HP23 displays both the current temperature read by the device to be calibrated
and the reference temperature (known environment). Press ENTER to activate the reference value
menu item and use the UP or DOWN arrow key to change each digit. Press ENTER to move the
cursor to the right. When done, press ENTER to save the value. Use the DOWN arrow key to select
. Press ENTER to activate the Acquire function. Press ENTER to confirm and save the
calibration point to the device memory. The HP23 automatically exits the menu.
Note: the procedure can be repeated with different reference environments so as to accumulate several
calibration points (temperature: maximum 2 points, humidity: maximum 100 points).
5.3.5 Calibration against a reference HygroClip 2 probe or other device
Connect the device to be calibrated to the HP23 as explained under 5.3.1. Connect the reference HygroClip 2
probe to the unused probe input of the HP23. Expose both the device and the reference probe to the same
stable environment and wait for full equilibrium with the environment. Whenever possible, provide some
ventilation.
o Press the MENU key and select either “Probe 1” or “Probe 2”. The reference probe is assumed to
be connected to the non-selected input. Press ENTER to activate the Probe 1 or Probe 2 menu
item.
o When the device is a HygroClip 2 probe connected to a HF5 or HF8 transmitter (or similar device),
select “Probe 1” and “Probe Sel” from the menu and press ENTER. Use the UP or DOWN arrow to
select the probe to be calibrated (HF5 transmitter: be sure to select probe 1)
o Use the DOWN arrow key to select either “Humi Adjust” or “Temp Adjust” (this can be done in any
order).
o Press ENTER to confirm and open the next sub-menu. Use the DOWN arrow key to select the
“Acquire (Ref = Probe)” menu item and press ENTER to confirm.
o Humi Adjust: the HP23 displays both the current humidity read by the device to be calibrated and
the value provided by the reference probe. Press ENTER to accept the calibration point. Press
ENTER to confirm and save the calibration point to the device memory. The HP23 automatically exits
the menu.
o Temp Adjust: the HP23 displays both the current temperature read by the device to be calibrated
and the value provided by the reference probe. Press ENTER to accept the calibration point. Press
ENTER to confirm and save the calibration point to the device memory. The HP23 automatically exits
the menu.
Note: the procedure can be repeated under different conditions so as to accumulate several calibration points
(temperature: maximum 2 points, humidity: maximum 100 points).
5.3.6 Adjustment of humidity and temperature
After saving calibration points to the memory of a probe or device, the HP23 can be used to do a humidity and
temperature adjustment of up to two probes, transmitters or other devices. Humidity and temperature
adjustment are two separate processes.
o Press the MENU key and select either “Probe 1” or “Probe 2”. Press ENTER to activate the Probe 1
or Probe 2 menu item.
