Adjust the 0 Ω "ADJ" turncap control to set the reading of
zero.
3.
Rotary to function switch to "EARTH WOLTAGE"
position and press to test. Earth voltage will displayed on
the LCD. When earth voltage is more than 10V, it may
result in errors in earth resistance measurement. Accurate
earth resistance measurement may not be made.
4.
Precision earth resistance measurement method :
(1)
Connect green, yellow and red test leads to
instrument terminals E, P and C with auxiliary
earth spikes P1, C1 stuck into earth "IN A
STRAIGHT LINE ".(Fig.1)
(2)
Rotary the function switch to suitable range then
press the pushbutton to test and take the reading.
5.
Simplified earth resistance measurement method :
(1)
This method is recommended where an earth
resistance higher than 10
it is not possible to drive auxiliary earth spikes. An
approximate value of earth resistance can be
obtained by the two wire system where is shown in
Fig. 2.
