Specification
8
Battery type Eight AA ALKALINE batteries.
Low battery warning symbol appears in the display and the
buzzer beeps if the battery voltage drops
below 7.8V.
Operating temperature 0 to +40˚C, relative humidity 80% or less, no
and humidity. condensation.
Storage temperature -10 to +50˚C, relative humidity 75% or less,
and humidity no condensation.
LED indication of live Illuminates if there is an alternating voltage of
circuit warning 50V 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.
LED indication of The P-E and P-N LEDs illuminate when the
correct polarity 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, PSC and RCD test
functions, the LCD reading is automatically
frozen for 3 seconds after measurement.
Display The liquid crystal display has 3 1/2 digits with a
decimal point and units of measurement (Ω,
MΩ, A, kA,V and ms) relative to selected
function. The display is updated approximately
five times per second.
Overload protection The continuity test circuit is protected by a
0.5A 600V fast acting (HRC) ceramic fuse
mounted in the battery compartment, where a
spare fuse is also stored.
The insulation resistance test circuit is
protected by a resistor against 1000 V AC for
10 seconds.
Mains Voltage On connecting test leads to the circuit under
Indication test on LOOP, PSC and RCD ranges, the LCD
reads V-PE. Sign ‘V-PE Lo’ or ‘V-PE Hi’ is also
shown when the voltage is 100V or less, or
260V or greater respectively.
