6. MEASURING METHODS
Battery voltage check
a.Before testing, rotate the function switch to "20Ω" range,
if the appears on the display, replace with new batteries.
b.Prior to measuring, if appears on the display,
replace with new batteries.
Do not apply voltage between the measuring
terminals at earth resistance measurements.
11 Earth voltage measurement:
(1)Test leads connection
5~10m
Auxiliary earth
spikes
Earthed electrode
under test
Yellow Green
(2)Rotate the function switch to"Earth Voltage" position,
earth voltage will display on the LCD. When earth voltage
is more than 10V. it may result in errors in earth resistance
measurement
