Data Measurement Modes
Available measurement options are volumetric water con-
tent (VWC) using the standard or high clay mode (see p.
8), up to two relative water content modes (see p. 10), or
measurement period (in microseconds). Relative water
content options will only appear if they are configured in
the software (see Meter Settings, p. 12). The period meas-
urement is available for users interested in performing soil
-specific calibrations (see Appendix 1).
Changing Rod Length
In order to get accurate volumetric or relative water con-
tent (VWC or RWC) readings, the rod length setting must
be correct. In the VWC modes, the currently selected rod
length appears in the lower left corner of the LCD screen.
The options are Turf (1.5”), Short (3.0”), Medium (4.7”),
and Long (7.9”) rods. Press the MODE button until the
LCD displays the rod length options screen. Pressing the
DELETE/CLR AVG button will allow you to toggle be-
tween the three choices.
Meter Calibration Mode
This mode allows you to calibrate the meter. The calibra-
tion procedure is performed in air and distilled water (see
Meter Calibration, p. 6). Requires firmware v. 6.5 or
greater.
