Preparation

Confirm that the verification clip components are intact. The verification clip helps verify proper function and accuracy for TEROS 10, 11, and 12 soil moisture sensors. A data acquisition system and the appropriate software are required, such as the ZL6 and Zentra Utility or Zentra Utility mobile.

⚠️ ATTENTION

TEROS soil moisture sensors require the most current software and firmware versions. Please make updates as necessary.

ZL6 firmware version 2.02 or higher
PROCHECK firmware version 1.70 or higher
ZENTRA Utility version 1.14 or higher

Go to metergroup.com/environment/downloads to find the current software or firmware version for the data logger being used.

Installation

1. Place Verification Clip on Sensor

Slide the verification clip onto the two prongs farthest away from the sensor cable with the arrow pointing toward the sensor.

⚠️ WARNING

Risk of personal injury is present. Sensor needle points are extremely sharp and will puncture skin. Please handle with care.

4. Verify Sensor Function and Accuracy

The sensor should read within the appropriate ranges.

METER logger	RAW count	VWC (m³/m³)
TEROS 11/12	2650 to 2730	0.332 to 0.363
TEROS 10	2650 to 2800	0.356 to 0.419

Non-METER logger	RAW count	VWC (m³/m³)
TEROS 10	1940 to 2050 mV	0.356 to 0.419
