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.

 Place the range switch [8] on the appropriate scale and the function switch [7]

on position "Ω". Then press PUSH-ON [9] and TIMER ON10] at the same time

and read the value on the indicator.

NOTE: When none of the E, P and C terminals is connected to the test pins, a

reading between 300 and 600 is normal (in function Ω, range 2 kΩ).
