To prevent wrong connection of test leads and to maintain safety, the
dedicated terminals used for continuity and insulation tests are automatically
covered when using the terminals for loop impedance and RCD tests
Instrument dimensions 175 X 115 X 86mm
Instrument weight 780g including batteries.
Reference conditions Specifications are based on the following
conditions except where otherwise stated:-
1．Ambient temperature: 23± 5℃
2．Relative humidity: 45% to 75%
3．Position: horizontal
4．AC power source: 230V, 50Hz
5． DC power source: 12.0 V, ripple content 1%
or less
6. Altitude: Up to 2000m
Battery type Eight R6 or LR6 batteries.
Low battery warning " " symbol appears in the display if the battery
voltage drops below 8V.
Maximum numbers of Approx. 700 times for use by continuity range or
measurements approx. 1000 times for use by insulation resistance
range.
Operating temperature 0 to +40℃ , relative humidity 80% or less, no
and humidity. condensation.
Storage temperature -10 to +50℃ , relative humidity 75% or less, no
and humidity condensation.
Illuminates if there is an alternating voltage of 20V
AC or more in the circuit under test before
continuity or insulation resistance tests. When DC
voltage is detected across the measuring terminal
the LED lights up.
The P-E and P-N LEDs illuminate when the wiring
of the circuit under test is correct. The
reverse
lamp is lit when P and N are reversed.
Auto data hold In the loop impedance and RCD test functions, the
LCD reading is automatically frozen for 5 seconds
after measurement.
Display The liquid crystal display has 3 1/2 digits with a
decimal point and units of measurement (Ω, MΩ,
V and ms) relative to selected function. The display
LED indication of
