Rod Length Water
8 inches (20 cm) 60 - 65%
4.8 inches (12 cm) 70 - 75%
3 inches (7.5 cm) 75 - 80%
1.5 inches (3.8 cm) 65 - 70%
Note: The meter does not read 100% in water as the reading is run
through soil equations created to be most accurate in the volumetric water
contents typically found in the selected soil type.
Unable to save data or load firmware from USB flash drive:
Confirm the drive is not full. Verify the drive has FAT or FAT32 format.
Firmware should be in the root directory; outside of any folders.
"No Sensor" appears on the display:
The sensor cable may be dirty or unplugged. Clean the cable connection
Check the cable connection to the display. Confirm that the probe block
is securely plugged into the display.

Troubleshooting
Sensor Function Verification:
Test readings can be taken in three standard environments; air, distilled
water, and sand saturated with distilled water. It is important that any
troubleshooting be done with distilled water instead of municipal well or
tap water. Test readings are made in a container of distilled water or satu-
rated sand. The container should have a diameter of at least 3 inches
(7.5cm) and should be tall enough so the rods can be completely im-
mersed or inserted.
Readings should be taken with the Soil Type set to Standard and the cor-
rect Rod Length selected. The meter should read VWC=0% in air. In sat-
urated sand, it should read between 35% and 45%. The table below shows
the approximate ranges of volumetric water content that are expected for
the different rod lengths in distilled water.
