digital true RMS multimeter BE52
Current measurements
Note
Never connect a voltage source to the multimeter's
measuring sockets when a current measuring range is
selected. Otherwise the device could be damaged.
Note
Observe that a measurement time of 30 seconds must
not be exceeded when carrying out a current
measurement of 10 A. After having carried out a
measurement up to 10 A, take a break for at least
15 minutes.
ü
The electrical circuit is deactivated. The capacitors are
discharged.
ü
The voltage in the measuring circuit is not higher than
600 V (CAT III) to earth.
1. Interrupt the circuit to be checked and connect the
measuring device in series with the consumer in this
circuit.
2. Depending on the expected measuring current, turn the
rotary switch to the following position:
- up to 6000 µA:
- up to 400 mA:
- up to 10 A:
.
3. Use the
MODE
button (15) to select the desired measuring
mode (for direct current:.
DC
indication) for alternating
current:
AC
indication).
4. Insert the plug of the black measuring tip into the
COM
(6)
measuring socket and the plug of the red measuring tip
into the
VΩ
(5) (up to 400 mA) or
10 A (14)
measuring
socket – depending on the selected range.
5. Switch off the voltage supply at the measuring object and
connect the measuring tips to the measuring object. For
direct current, make sure that the polarity of the
connection to the measuring object is correct (in series;
red to plus, black to minus).
6. Switch the measuring circuit back on and read the
measured value from the display.
7. If the
OL
indication (exceedance of the measuring range)
appears after the manual range selection, immediately
switch over to the respectively next higher range. If the
OL
indication appears and the maximum range has been
set already or in case of the automatic range selection,
immediately switch off the voltage supply at the measuring
object and disconnect the measuring device from the
measuring object.
Info
If you have selected the 10 A range for safety's sake,
but the measuring current amounts to less than
400 mA, switch the measuring circuit back off. Plug
the red measuring tip into the
VΩ
measuring socket
and select a measuring range in the mA range. Switch
the measuring circuit back on.
Example:
Info
If there is no indication and all connections have been
established correctly, the cause of the fault may be a
defective internal fuse protecting the current
measuring ranges (see chapter Fuse replacement).
Measuring resistance
Warning of electrical voltage
Before carrying out resistance, continuity or diode
measurements, switch off the current of the electric
circuit and discharge all capacitors.
1. If possible, disconnect other circuit areas from the
resistance to be measured, since they may have an impact
on the measurement.
2. Set the rotary switch to the
Ω/
/CAP
(20) position,
then use the
MODE
button (15) to select the resistance
measurement (
MΩ
indication).
3. Insert the plug of the red measuring tip into the
V/Ω
measuring socket (5) and the plug of the black
measuring tip into the
COM
measuring socket (6).
4. Connect the measuring tips to the measuring object.
ð
The measuring device may take some time to display a
stable value. This is due to the measuring principle and
not a malfunction.
ð
The measured value will be indicated on the display.
