Measuring DC and AC voltages
Set the rotary switch (6) to the „1000 V
“ position.
í
Scan the measuring points with the two probes without
pressing the measurement pushbutton (8) in the probe.
The tester alternately measures the DC and the AC voltage
and displays the higher measured value in both digital and
analog form. The symbol behind the „V“ character shows
whether a DC or an AC voltage is displayed.
When the measured value is steady, the word „
DATA
“ is
shown on the LCD display. A short sound signal points to
this.
í
When you briefly press the measurement pushbutton (8)
in the probe, the word „
HOLD
“ is displayed in addition to
„
DATA
“ and the measured value on the digital display is
held.
If, after storage of the measured value, the voltage drops to
a value below 10 V, the held measured value is cleared the
instant the voltage rises again and „DATA HOLD“ is
blanked.
The digital display then again shows the actual measured
value. The measured value can be held as soon as it has
reached a steady state again.
If you press the measurement pushbutton (8) even though
the measured value is not (yet) stable, only „HOLD“ is
shown and not „DATA“. When pressing the measurement
pushbutton the currently existing measured value is held on
the digital display. The pointer of the analog indicator con-
tinues to constantly follow the actual measured value.
í
When pressing the pushbutton again, you clear the
measured value. The digital display then shows the
actual measured value.
í
You can use the lamp in the probe (9) to illuminate the
measuring point or the LCD (5). Press the pushbutton
„AUTO /
⊗
“ (2). The lamp lights as long as you keep the
pushbutton (2) pressed.
Note!
☞
The permissible overload capacity on the voltage
measuring range is 1200 V
.
If this value is exceeded, a sound signal draws
your attention to it.
The input resistance on the voltage measuring
range is 880 k
Ω
. With a blown or a missing fuse,
the voltage measurement is made with an input
resistance of approximately 5 M
Ω
.
