Repair Maintenance

Changing the INTERCAP® Sensor

(HMP60 and HMP63)

This procedure restores the humidity measurement accuracy of the probe.

No adjustment after the sensor change is needed.

To perform this procedure, you need a new INTERCAP® 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 INTERCAP® sensor and

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

touch the temperature sensor.
