Operating Instructions
Powering On/Off
Press and hold the power button (typically located centrally on the control panel) to turn the device on or off.
Basic Measurements
Once powered on, the Hygromaster L will automatically begin displaying readings for:
- Relative Humidity (0-100% RH)
- Air Temperature
- Dewpoint Temperature
- Specific Humidity (GPP, g/Kg)
Allow a few moments for the readings to stabilize, especially when moving the device between environments with different humidity or temperature levels. The device offers a fast response time for efficient data acquisition. It is recommended for general measurement and applications, such as flood damage restoration.
Navigating Menus and Settings
Use the directional buttons on the control panel to navigate through menus and adjust settings. The central button typically acts as a selection or confirmation button.
