Page 13: Chapter 2 Product Overview
HMM100 modules do not incorporate probe heating or chemical purge functionality. If the measurement environment is prone to condensation, or likely to cause chemical contamination of the sensor, other Vaisala instruments may be more suitable to the application. The cable and probe of the HMM100 are attached at the factory. They should remain connected to the module at all times;... -

See Figure 12 below. NOTE The installation holes on the component board are compatible with Vaisala HMM22 and HMM30 humidity modules. Remember to disable temperature compensation (if any) in the measurement system when replacing an old module with the HMM100. The temperature compensation in the HMM100 is always enabled. -
Page 25: Installing The Probe
Install the probe in the location. Use the probe mounting clamp (Vaisala order code 226067) if needed. Insert enough cable to the same space with the probe in order to prevent heat conduction, and to make it easy to move the probe when performing a calibration. -

Page 51: Chapter 5 Maintenance
Install a new filter on the probe, and tighten it so it is finger-tight. Make sure the filter sits straight and meets the threads properly. New filters can be ordered from Vaisala. For available filters, see section Filter Types on page 14. The order codes of the filters are listed in section Options and Accessories on page 68. -
Page 52: Figure 16 Changing The Sensor
USER'S GUIDE____________________________________________________________________ Remove the filter from the probe by turning it counter-clockwise. Remove the damaged sensor and insert a new one. Handle the new sensor by the plastic socket. DO NOT TOUCH THE SENSOR PLATE. Perform a calibration and adjustment using the CRH command as instructed in section Capacitance Calibration (CRH) on page 58. -
