8.0 TEMPERATURE BEHAVIOUR OF THE SENSORS
During humidity and temperature measurement there are many parameters which
affect the time required until the real measurement value is displayed.
The parameter which may cause the largest measuring errors, is the difference in
temperature between the sensors or between the measuring instrument and the
substance to be measured or the air.
To shorten the time required for the sensors/instrument to reach the same
temperature as the substance or air, proceed as follows:
• RH1 : Mo ve the instrument around in the air
o Hold the instrument securely in your hand and move it carefully backwards
and forwards. Do not hit other objects with the instrument!
• RH5 : Mo ve the sword-shaped sensor into the paper stack
o First push the sword only a short distance into the stack (10 cm). At brief
intervals (10 seconds), push it a few more centimetres into the stack.
If the temperature difference is large, repeat this procedure (several
times if necessary).
o If you use the sword cover to protect the sword-shaped sensor, make sure
they are both the same temperature.
• In this case, push the sword cover little by little into the stack and leave
the sword-shaped sensor in the cover long enough to ensure a correct
measurement result!

LOOKING AFTER THE INSTRUMENT
Do not drop the instrument or expose it to excessive temperatures. Only clean it
with a lint-free, dry cloth. The instrument is not waterproof. Do not immerse the
sensor in liquid.
For more information on looking after the instrument, see www.checkline.com
How often you need to check the instrument depends on the use and the required
level of accuracy. You can check humimeter RHx instruments yourself (see Optional
accessories)
For a fee we can also carry out a calibration at the factory. In this case you will also
receive a calibration certificate.
