5.2. AC, AC+DC VOLTAGE MEASUREMENT
CAUTION
The maximum input AC voltage is 690V 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. 9: Use of the instrument for AC voltage measurement
1. Select position
V
2. Press the
MODE/MXMNPK
key until symbol
“
AC
”
or
“
AC+DC
”
is displayed. The
instrument automatically recognizes AC or DC signals.
3. Insert the red cable into input terminal
V
L
and the black cable into input terminal
COM/E/N
.
4. Position the red lead and the black lead respectively in the spots of the circuit to be
measured (see Fig. 9). 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 message
“
>690V
”
(see Fig. 9), the maximum measurable value
has been reached.
6. If the display shows the messages
“
<32Hz
”
or
“
>1000Hz
”
(see Fig. 9), the value of
frequency is out of the measuring range
32Hz ÷ 1000Hz
.
7. To use HOLD, MAX/MIN/PK, H/H%/H functions, see § 4.2
