3.2.- Use
Before starting measurements, carefully read the Safety Advice section.
Connecting the test pins:
Connect the green, yellow and red test pins to the terminals E, P and C with the
earth rods P1, C1 placed in the ground "in a straight line" (see figure).
Place the function switch [7] onto the ACV position and ensure that the voltage
reading is less than 10 V AC. If not the accuracy of the earth resistance
measurement cannot be guaranteed.
If the PUSH-ON [9] button is pressed and the operating indicator [2] does not
come on, thisl means that there is an open circuit between the test pins.
