15.3 Installing QMT110
Shovel
For the most reliable measurements:
• The measurement site must be undisturbed ground, 1 m² (10.76 sq ft), and typical of the
surface of interest.
• The ground surface must be level with respect to the immediate area within a 10‑meter
(32‑foot 10‑inch) radius.
Correct positioning of the sensor and insulation of the sensor cable are essential for the
measurements.
In AWS310-SITE, you can have up to 2 QMT110 sensors.
1. Choose the installation place. Make sure that the sensor is located within cable length
of the QML data logger.
2. Dig a hole that is slightly deeper than the desired installation depth of the sensor.
