8. Voltage Measurement (V AC/DC)
You can use this instrument for voltage measurement from 25V to 600V
AC or DC.
* Keep the function selector switch to “V ” position and
apply the input.
* The instrument automatically displays whether the input
is AC or DC along with the value of the external voltage.
* If the value of voltage is < 25V (AC or DC), the display
“025V” flashes. If the value of the voltage is > 600V (AC
or DC), a continuos acoustic signal is generated.
* When reverse DC is applied it displays “-dc”
Additional features available in Insulation measurement ranges.

9. Default Live Circuit Warning
When more than 25V (AC or DC) is applied to the terminals the
instrument defaults to voltmeter on all switch positions. In addition the
beeper will sound on all switch position (except the V position).
When external voltage>25 V is present, Insulation Ohm and Continuity
Tests are inhibited.
When external voltage <25 V is present, only the Insulation Tests are
available !!
Note : The default live circuit warning does not operate
(i) when in STOPWATCH mode.
(ii) when in MENU structure.
