Golf Courses, Tournaments and Sporting Events

The main thing to look for before tournament play or events is not to need an actual

percentage reading of say 30% but to look for consistency. If all the greens have the

same percentage of soil moisture and they all have the same reading on the Turf-Tec

Penetrometer, they will all respond to the ball impact the same way. If all sports field

areas are also consistent, they will have the same footing and ball bounce. The key to

playability is consistency from green to green or area to area on an athletic field with the

relationship of soil moisture and compaction.

Adjustment of Readings - Calibration

The Turf-Tec Digital Moisture Sensor comes pre-calibrated from the factory to read

100% if the probe tips are placed into most water types. If you adjust the readings, Turf-

Tec will re-calibrate your unit to factory settings if required, however the shipping

charges will not be covered under the one year warranty period.

To adjust the readings, follow the below procedure.

1. First, be sure probes are tight in the foot block. Low or sporadic readings

will occur if probes are not tight. (Do not over tighten)

2. Extend the probe tips out of foot to one inch level.

3. Wet an area that is representative of the area you will be testing (same soil type)

with your irrigation water.

4. Insert the probes into the soil 2-3 times to clean them.

5. Insert the probes into the wet area and check the digital display. If the readings

are over 100%, there is probably sodium or other minerals present in your

irrigation water or soil. That value should be determined by sending in a water

sample to a qualified lab or using an EC Meter.

6. Open the meter top by unscrewing the four screws in the face of the meter.

7. Place the probes again directly into the area of saturated soil.

8. Locate the calibration adjustment screw on the circuit board that is attached to

the bottom of the meter box. (Photo below)

9. Insert a small screwdriver into the calibration adjustment screw and turn slightly

until the reading on the digital display reads 100%.

10. Remove the probes from the soil and repeat the process a couple time to

be sure the probes are clean and the reading is stable at 100%.

11. Reattach face securely with four screws.
