5. Setup
5.1 Battery Installation
The Werkzeyt B29820 requires 3x LR44 button cell batteries. These are typically included with the device.
- Locate the battery compartment cover on the back of the device.
- Open the cover (you may need a small screwdriver or coin).
- Insert the 3 LR44 batteries, ensuring correct polarity (+/-) as indicated inside the compartment. If there is a plastic tab, remove it before use.
- Close the battery compartment cover securely.

It also details the measurement ranges for wood (6%-48%), building materials (0.1%-11.0%), and temperature in Celsius (0°C-50°C) and Fahrenheit (32°F-122°F). The bottom left confirms the use of 3x LR44 batteries.
6. Operating Instructions
6.1 Powering On/Off
The device powers on automatically when the measurement button is pressed. It features an automatic shut-off function to conserve battery life after a period of inactivity.
6.2 Taking a Moisture Measurement
To measure the moisture content of a material:
- Ensure the probes are clean and free from debris.
- Carefully press the two sharp measurement probes into the material you wish to test. Ensure both probes penetrate the surface adequately for an accurate reading.
- Press and hold the yellow measurement button. The moisture percentage will be displayed on the LCD screen.
- Observe the indicator lights for a quick assessment:
- Green Light: Indicates low moisture content.
- Yellow Light: Indicates moderate moisture content.
- Red Light: Indicates high moisture content.
- Release the button to turn off the display or wait for automatic shut-off.

6.3 Measuring Air Temperature
The device also measures ambient air temperature. This reading is typically displayed alongside the moisture reading or can be accessed by a specific mode (if available, though not explicitly stated for this model, it's usually automatic or a button press). Refer to the display for the temperature value, usually indicated with °C or °F.
7. Measurement Ranges and Accuracy
The Werkzeyt B29820 provides the following measurement capabilities:
