3.1 FUNCTIONS OF THE SWITCH

To access to the functions of the switch, set the switch to
, , , , ,
3.1.1 Voltage measurment
The instrument measures :
The AC voltage at low input impedance (V
Direct voltages (DC) ;
Alternating voltages (AC).
To measure a voltage, proceed as follows :
1. Set the switch to , or
device is in AC mode only.
2. For or ,select AC or DC by pressing
default, the device is in DC mode. Depending on your
selection, the screen displays AC or DC.
3. Connect the black lead to the COM terminal and the red
lead to « + » ;
4. Place the contact tips on the terminals of the circuit to be
measured ;
The measured voltage is displayed on screen.
3.1.2

Resistance measurement

Attention : all resistance measurements must be made in the
absence of any voltage.
To measure a resistance, proceed as follows :
1. Set the switch to
