Moisture Measurement Operation
7
7.8 Set Reference Mode
1. Select the ‘Set Reference’ mode from the menu (Moisture mode/Set
Reference
); see Figure 7–13 above. This mode is only available for
pinless measurements, including the optional MR12 Ball Moisture probe.
2. When the ‘Set Reference’ mode is selected, the displays are affected in
the following ways:
• Thermal/Visible Camera modes: A delta (triangle) symbol is shown after
the moisture reading indicating that the reading represents the current
measurement minus the reference value (the measurement recorded at
moment the ‘Set Reference’ mode was selected).
• Moisture-only mode: The reference value, with delta symbol, is shown on
the right side of the display and the moisture reading (offset by the refer-
ence value) is shown on the left in large digits.
1. All measurements taken subsequently will be relative to the reference val-
ue. For example, if the reference value is ‘20’ (representing the driest area
of the material under test) and a measurement of ‘25’ is taken (in an area
with higher moisture content), the measurement will show ‘5’ (25 – 20 = 5).
As implied, this mode is useful for comparing wet areas to a dry area
reference.
2. To remove the reference value and exit the mode: Remove the meter sen-
sor from the area under test, so that the sensor is no longer touching a
surface and is clear of any objects, and then select the pin-mode from the
Moisture Mode menu.
