(4) Measurement
● Press TEST or the remote control switch to start a continuous
measurement. Press TEST or remote control switch again to stop
measurement.
Display example
Fig. 9-7
The LCD shows “>2099Ω” when the measured result exceeds the
display range (over-range).
(5) Simplified measurement value
Two-pole method is used for simplified measurement. In this method,
earth resistance value re of earth electrode connected to terminal C(H) -
see Fig. 9-3 - is added to true earth resistance value Rx and shown as an
indicated value Re.
Re = Rx + re
If the re is known beforehand, true earth resistance value Rx is calculated
as follows.
Rx (true resistance) = Re - re
