Changing the HUMICAP® 180R Sensor

(HMP110, HMP110D and HMP113)

NOTE

Replacing the humidity sensor of the HMP110

, HMP110D and HMP113

is not necessary in normal operation. If the accuracy of the probe does

not seem to be within specification, it is likely that the accuracy can be

restored by performing

the adjustment procedure. See section Two-Point

Adjustment of RH Measurement (HMP110, HMP110D and HMP113)

on page

56.

Follow this procedure to replace the humidity sensor of the HMP110,

HMP110D and HMP113 in case it has been damaged, or normal

adjustment is not sufficient to restore the measurement accuracy.

Calibration and adjustment of the humidity measurement is required after

the sensor change.

To perform this procedure, you need a new HUMICAP® 180R sensor. It

is also recommended that you replace the filter with a new one. For

order codes, see section Options and Accessories on page 70.

1. Remove the filter from the probe by turning it counter-clockwise.

2. There are two sensors under the filter, the HUMICAP® sensor and

a temperature sensor. Identify the HUMICAP® sensor – do not

touch the temperature sensor.

3. Pull out the old HUMICAP® 180R sensor and insert a new one.

Refer to Figure 25 on page 61. Handle the new sensor by the plastic

frame. DO NOT TOUCH THE SENSOR PLATE.

4. Perform a two-point adjustment of the RH measurement as

instructed in section Two-Point Adjustment of RH Measurement

(HMP110, HMP110D and HMP113) on page 56.

5. Attach a new filter on the probe.
