RANGE ACCURACY RESOLUT.
Input resistance is 10 MΩ
Overload security: DC or AC peak value is 1000V.(except the
200mV range which has a max. value of 250V rms)
NB:
1. In case you do not know the voltage range, set the
FUNCTION-switch to the highest range and turn
it down gradually, if necessary.
2. Set the FUNCTION-switch to a higher range,
when only the figure "1" is displayed. In this case,
the value is out of range.
3. The maximal input voltage is 1000 V. Higher volta-
ges cannot be measured.
4. Take the utmost care, when measuring high voltages.
11.2 Measuring alternating voltage (VAC)
1. Put the BLACK cord to the “COM”-connector
and the RED one to the “V/Ω”-connector.
2. Adjust the FUNCTION-knob to the desired
“V~” position and connect the cords to the sour-
ce or charge to be measured. The polarity of the
measuring pins is insignificant.
3. Readout the value in Volt.
RANGE ACCURACY RESOLUT.
Input resistance: 10 MΩ
Frequency range: 40 .... 400 Hz
Overload security: AC 750 rms or DC 1000V peak.(Continuous on
all ranges)
Indication: Average value (rms of sine shape)
NB:
1. In case the voltage range is unknown, set the
FUNCTION-switch to the highest range and turn
it down gradually, if necessary.
2. Set the FUNCTION-switch to a higher range,
when only the figure "1" is shown on the display. In
this case, the value is out of range.
3. The maximum input range amounts 750 V. Higher
voltages cannot be measured.
4. Take the utmost care, when measuring high voltages.
11.3 Measuring direct current (ADC)
1. Connect the BLACK cord to the “COM”-con-
nector. Connect the RED cord to the “mA”
connector, for measuring upto 200 mA. Connect
the RED cord to the “A” point, for measuring
within a higher current range, upto 20A.
2. Set the FUNCTION-switch to the desired “A ”
position and connect the cords in series to the
respective charge. Mind the correct polarity (red
is + and black is -), otherwise the display will add a
minus-sign to the value. The polarity of the RED
cord will be shown, simultaneously with the value
of the current.
3. Readout the value in (milli) Ampere.
RANGE ACCURACY RESOLUT.
Overload protection: 0.2/250V fuse, 20A range is not fused.
NB:
1. In case you do not know the current range, set the
FUNCTION-switch to the highest range and
lower it gradually, if necessary.
2. Set the FUNCTION-switch to a higher range,
when only the figure "1" is displayed. In this case,
the value is out of range.
3. The 20A range is not protected with a fuse.
Never measure for more than 10 seconds.
11.4 Measuring alternating current (AAC)
1. Put the BLACK cord to the “COM”-connector
and the RED cord to the “mA” connector, for
measuring upto 200 mA. Connect the RED cord
to the “A” point, for measuring a higher current
range, upto 20A.
RANGE ACCURACY RESOLUT.
Overload protection: 0.2/250V fuse, 20A range is not fused.
