OPERATING INSTRUCTION

The following instructions describe the use of the instrument for the execution of measurements on
photovoltaic systems. The arguments are still valid for other types of application.
1. Fix the stirrup in a central position of the edge. The stirrup is provide of a fixing screw compatible with
holes placed on the back side of the PV module frame.
2. Check that the stirrup is resting the edge of the form.
3. Select the Reference Cell to be used (MONO or MULTI) and connect its output to the connection cable.
4. Always check the parallelism between the sensor and the photovoltaic module under consideration (error
max 2 °). The non-perfect parallelism between the sensor and the PV module surface could affect the
outcome of the measure.
5. Tighten the screws.
6. Expose the sensor to the test conditions (radiation temperature, inclination) at least 1 minute before
performing the readings in order to avoid working with the sensor not yet in steady state.
