5.2. MOISTURE MEASUREMENT OF MATERIALS
The instrument can perform moisture measurements with contact (typically wood and
construction materials) in the following modes:
➢ MOI INT → Use of the in-built sensor (see Fig. 1
to be tested.
➢ MOI EXT → Use of the provided external probe inserted in the instrument
connector (see Fig. 1
5.2.1. Measurement with in-built sensor
Do not carry out any measurements in case gas, explosive materials or
flammables are present, or in dusty environments. Do not expose the in-built
sensor to mechanical shocks.
1. Switch on the instrument using key ON/OFF.
2. Use keys or to select the measuring unit for temperature (see § 4.3.3).
3. Press key MOI. Indication

4. Position the in-built sensor near the surface of the item to be measured, paying
attention not to cover it with your hand, and check that the main display shows value

"
5. In case the value is not zeroed, press and hold (>2s) key MODE/ZERO. Symbol

appears on the display for a moment and the value is zeroed on the main
display (see Fig. 8
6. Rest the instrument on the surface of the item to be measured. The value of relative
humidity is shown on the main display. The value of air temperature is shown on the
secondary display.
7. Set possible alarm conditions on measurement (see § 4.3.10).
8. Wait for a steady result on the display and press key MEM/ALM to save the measured
result in the instrument
