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 68.
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.
