2.1. GENERAL
V

AC
Set the switch to
V
or to the
M Ω
positions.
Start by making sure of the proper operation of the voltage
measurement, by measuring a known voltage before each
use. For example on a power outlet.
Then, using the leads, connect the device to be tested to the
terminals of the instrument.

The instrument displays the voltage on the terminals. It detects whether the voltage is AC or DC and, if it is AC, displays its frequency.

At start-up, the instrument indicates the remaining battery
life. If the battery voltage is too low to ensure correct operation
of the instrument, it so reports.
The batteries must then be replaced (see § 4.2)), since the
battery life indication is no longer reliable.
Except for the voltage measurement, all measurements are made on devices in the power-off condition. It is therefore
necessary to check that there is no voltage on the device to be tested before making a measurement.
2.2. VOLTAGE MEASUREMENT
In the M
Ω
settings, the symbol indicates that the voltage is too high (> 25
V) and that insulation measurements are prohibited.
If the voltage is > 15 V, continuity, resistance, and capacitance measurements
are prohibited.
