b) (Rechargeable) batteries
• Correct polarity must be observed while inserting
the (rechargeable) batteries.
• (Rechargeable) batteries should be removed
from the device if it is not used for a long period
of time to avoid damage through leaking. Leaking

battery leakage and device damage.
• (Rechargeable) batteries must not be dismantled,
short-circuited or thrown into re. Never recharge
non-rechargeable batteries. There is a risk of
explosion!

If you use the product as a stand-alone device, you need
not change the channel.
• Press and hold the CH/+ button for approx. 3 seconds until the
circular arrow appears above the channel number.
• Briey press the CH/+ button to set the desired channel (1 – 8).
• To exit selection mode, press and hold the CH/+ button for
approx. 3 seconds until the circular arrow goes out.
b) Display/delete the MIN/MAX values
• Briey press the MIN/MAX/- button. The maximum measured
values and the MAX indicator appear on the display.
• To reset the maximum measured values, press and hold the
button MIN/MAX/- for approx. 3 seconds.
• Briey press the MIN/MAX/- button. The minimum measured
values and the MIN indicator appear on the display.
• To reset the minimum measured values, press and hold the
button MIN/MAX/- for approx. 3 seconds.

12. Calibration
Perform a calibration only if you have another reliable and
calibrated measuring device at hand.
Do not use measured data from the internet, radio,
television or newspaper, since they may not necessarily
match the current conditions for your location.
We recommend using a mercury or alcohol thermometer
as a reference.
Place the product and the reference thermometer in a
shady area at a sufcient distance to any heat sources.
Wait approximately 48 hours and then compare the
measured values before calibrating the product.
a) Air humidity
• Press and hold the SET and MIN/MAX/- buttons at the same
time for approx. 3 seconds until the humidity value ashes.
• Use the MIN/MAX/- and CH/+ buttons to change the value in
increments of 1 %. Press and hold the button to fast forward.
If you have changed the original measured value, the indicator
CALIBRATED appears next to the measured value.
• To return to the original, uncalibrated value, briey press the
SET button. The indicator CALIBRATED goes out.
• To exit calibration mode, press and hold the SET button for
approx. 3 seconds until the measured value stops blinking.
15

• If no button is pressed for 15 seconds, the product
automatically returns to normal display mode.
b) Temperature
• Press and hold the SET and CH/+ buttons at the same time for
approx. 3 seconds until the temperature value ashes.
• Use the MIN/MAX/- and CH/+ buttons to change the value in
increments of 0.1 degrees. Press and hold the button to fast
forward.
If you have changed the original measured value, the indicator
CALIBRATED appears next to the measured value.
• To return to the original, uncalibrated value, briey press the
SET button. The indicator CALIBRATED goes out.
• To exit calibration mode, press and hold the SET button for
approx. 3 seconds until the measured value stops blinking.
• If no button is pressed for 15 seconds, the product
automatically returns to normal display mode.
