Humidity measurement
Material/building moisture cable,
Part no. 0636.0565
Description:
The building moisture cable 0636.0565 is suitable for qualitative measurements in the material/
building moisture sector. The measuring principle is based on resistance measurement.
By scaling, values between 100 and 0 are allocated to the resistance values making an assessment
of the material/building moisture possible.
Note:
This probe is not suitable for measuring resistance in the same way as a multimeter.
Connecting to testo 400 or testo 650 reference instruments:
If the instrument is switched on with the 0636.0565 probe attached, the instrument shows the
values in kΩ. The instrument measures the parallel connection between a 100 kΩ fixed resistor and
the measurement resistance at both banana plugs.
Example: 100k

Scale the system in the “building moisture” application range as follows:
1. Press to go to the main menu.
2. Select “probe” - Confirm with .
3. Set “Scaling” - Confirm with .
4. Select channel: right connection socket = Channel 2
left connection socket = Channel 1
Confirm with .
5. Select “%” or “n” - Confirm with .
6. Adjust with arrow buttons:
0 to 100 k
ΩΩ
100 to 0 % or n
Effect: Short-circuit
➪
Display = 100.
High-value resistance at input
➪
Display = 0.
All of the values relevant for measuring building moisture lie inbetween:
100 to 66 WET
65 to 51BUILDING MOISTURE
50 to 21 BUILDING DRYNESS
20 to 1 DRY
0 to 1 VERY DRY
