7.2 Sensor Replacement
A damaged capacitive humidity sensing element can be replaced by the user against an E+E replacement sensor
(see chapter 8 Spare Parts and Accessories)
Sensor replacement procedure
1.
Switch off supply voltage.
2.
3.
Remove the filter cap from the tip of the probe with utmost care not to touch the sensors.
4.

5.
Shorten the leads of the replacement sensor from 10 mm (0.39") to 6 mm (0.24").
6.
Solder in the new humidity sensor, the active side shall face the temperature sensor.
7.

NOTICE
▪
When replacing the humidity sensor element the factory calibration is not any longer valid.
▪
The humidity sensor element is an Electro Static Discharge (ESD) sensitive components and shall be
handled as such.
▪
Hold the humidity sensor element only by the leads. Never touch the active surface of the sensor.
PLEASE NOTE
The replacement of the humidity sensor element may be performed by qualified staff only.
Since the
performance of the instrument after the sensor exchange depends on the overall accuracy of the adjustment
procedure, it is strongly recommended to return the device to E+E for sensor replacement.
