|The measurement probe with cable is attached to the component board at Vaisala. Do not disconnect and reconnect the cable.|
- Attach the module securely using the mounting holes on the corners of the component board. Use the optional mounting bracket (Vaisala order code 225979) if needed.
- Make sure that the module has a good earth connection from the plated mounting hole.
|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.|
