Buzzer
The equipment features a buzzer which buzzes when the
terminals of the equipment are connected to a voltage source.
The sound volume is proportional to the voltage up to
approximately 30 V then becomes stable.
3. USE
3.1
Implementation
Connect the cords to the equipment using the forked
terminals and in compliance with the terminal colours.
Pay out the cords and set the stakes at the ends.
Connect the cords to the stakes using the alligator clips.
Return to the equipment, press the pushbutton and read
the measurement results.
3.2
Earth resistance measurement
To measure the earth resistance, it is advisable to use the
"62%" method (method using two stakes). This measurement
requires the use of the earth Kit components (see paragraph
7 to order).
Earth
connection
Turn off the installation power supply and disconnect it
from the earth by opening the ground terminal bar.
1. Shor t-circuit the terminals E and ES using the
corresponding terminal bar and connect them to the earth
point to be measured.
2. Push rod H as deep as possible into the ground at a
distance "a" from the earth to be measured.
Note: the deeper the earth the greater this distance should
be (larger area of influence). If possible, it is advisable to
have a distance "a" > 25 m
3. Insert rod S into the ground on a line between the earth
connection E and rod H, at a distance of 62% of "a".
