Store devices with lithium batteries in a cool, dry place, away from heat sources, ideally in the original packaging. Lithium batteries are hermetically sealed. Never attempt to open lithium batteries. Only use powder extinguishers or other suitable extinguishing agents to extinguish a burning device containing lithium batteries.

Risk of fire due to incorrect polarity

Incorrectly inserted batteries may destroy the device or the batteries. Ensure that proper polarity is observed when inserting batteries.

5Display of the humidity values in 5 zones

(the black bar indicates the respective zone):
Dry, corresponds to	0 %	-	29 %
Slight Dry, corresponds to	30 %	-	39 %
Comfort, corresponds to	40 %	-	49 %
Slight Wet, corresponds to	50 %	-	59 %
Wet, corresponds to	60 %	- 100 %

Using the device

Setting the desired humidity target value

To use the alarm function of the device, set the desired air humidity target value between 30 % and 70 %. Hold down the SET button for 2 seconds. When the indicator r is flashing, repeatedly press the SET button to adjust the target value in 5 % increments. If later the currently measured humidity differs by more than ± 5 % from this value, the LCD will flash to warn you. The optimum humidity for normal instruments is between 40 % and 49 %. Use the setting ‘-’ if you do not want to use the alarm function.

Temperature display

The display eshows the current ambient temperature. Press the SET button to switch between units Celsius and Fahrenheit. The measurement range is from -30 °C to 50 °C or from -22 °F to 122 °F, respectively.

Attaching the device

Attach the device with the clamp to the instrument or use the Velcro strap to attach the device to the instrument.

Exchanging the battery

If the display becomes weak, the battery will soon be exhausted and must be replaced by a fresh one of

same type (CR2032). To do this, pull the battery holder as shown on the right from the device. Remember polarity of the old battery! Take it out of the holder and insert the fresh one with the same polarity. Slide the battery holder back into the unit.

If the device does not operate as described in this manual and switching power on / off does not solve the problem, remove the battery and insert it again to possibly fix the problem.
