Humidity display configuration
The humidity can be displayed in % RH, g/m
3
, g/kg and gr/lb, and
the dew point temperature in dp °C and dp °F.
1. Press the down key (11) until the desired unit is displayed.
– The humidity or dew point temperature will be displayed in
the selected unit in the lower measured value display (18).
– The unit (19) will be indicated on the display (1).
Measuring mode
1. Press the keys Right/back (10) or Left/menu (13) until the
desired measuring mode is displayed.
– The selected measuring mode (15) will be indicated on the
display (1).
The device comes with the following measuring modes:
Holding the measured value
1. Set the measuring mode to HOLD.
– The current measured value will be held and displayed.
– The device will hold this value until the measured values
are set back or the device is switched off.
Resetting the measured values
1. Press the OK button (12) for approx. 2 seconds.
– All previously stored measured values of the measuring
modes AVG, MIN, MAX and HOLD will be set back.
– All measured values are then determined anew based on
the measurement proceeding in the background.
Measured value storage
Please note that measured values cannot be saved on the device
itself. In order to save measured values, the device has to be
connected to a PC via a USB cable using the SmartGraph
software.
1. Briefly press the OK button (12).
– The displayed measured value will be saved in the
software.
Further information can be gathered from the help text of the
SmartGraph3 software.

TH The device shows the air temperature and humidity (like a
thermohygrometer).
IR The device shows the surface temperature (like a
pyrometer).
IR DP The device shows both dew point and surface temperature
(combination of thermohygrometer and pyrometer).
