5.3. AC, DC, AC+DC VOLTAGE WITH LOW IMPEDANCE (LOZ)
CAUTION
The maximum input AC/DC voltage is 1000V to earth. Do not measure
voltages exceeding the limits given in this manual. Exceeding voltage limits
could result in electrical shocks to the user and damage to the instrument.
Fig. 8: Use of the instrument for AC/DC voltage measurement with LoZ function
1. Select position
LoZV
. The symbols
“
LoZ
”
and
“
DC
”
appear on the display.
2. Press key
MODE/MXMNPK
to select
“
AC
”
or
“
AC+DC
”
measurement. Anyway, the
instrument automatically recognizes AC or DC signals.
3. Insert the red cable into input terminal
V
/+
and the black cable into input terminal
COM/
.
4. Position the red lead and the black lead respectively in the positions of the circuit to be
tested (see Fig. 8) for AC voltage measurement or in the positions with a positive or
negative potential of the circuit to be tested (see Fig. 6) for DC voltage measurement.
The display shows the value of voltage. On the top of the display on the right side, the
value of voltage frequency is displayed. Press key
MODE/MXMNPK
to display the
value of frequency with a higher resolution.
5. If the display shows the messages
“
<32Hz
”
or
“
>1000Hz
”
(see Fig. 8), the value of
frequency is out of the measuring range
32Hz ÷ 1000Hz
.
6. When symbol
“
-
”
appears on the instrument's display, it means that voltage has the
opposite direction with respect to the connection in Fig. 6
7. To use functions HOLD, MAX/MIN/PK, H/H%/H, see § 4.2
