digital true RMS multimeter BE52
Attaching the warning signs
Prior to initial start-up, make sure that the warning sign at the
rear of the device and the warning sign below the stand are in
your local language, if not, paste the proper ones over them.
Warning signs in your native language are supplied along with
the device. Please proceed as follows to attach the warning
signs to the rear of the device:
1. Remove the labels in your local language from the supplied
film.
2. Stick the labels onto the places that are provided for this
purpose on the stand and on the fuse compartment below
the stand.
Undefined displays
If measuring inputs are open or touched by hand, this can lead
to undefined displays. This is not a malfunction but a reaction of
the sensitive measuring input to existing interference voltages.
Normally, when there is no high interference level at the
workplace or in case of a short circuit at the measuring input
zero is displayed immediately. Or, if the measuring object is
connected, the exact measured value is displayed. Fluctuations
in the displayed value by some digits are systemic and within
the tolerance.
If the resistance measuring range, the continuity testing range
or the diode test was selected and the measuring input is open,
the
OL
indication (exceedance of the measuring range) will be
displayed.
IMPORTANT INFORMATION ON THE MEASURING PROCESS!
Warning of electrical voltage
Improper handling of the measuring device entails a
risk of electric shock!
Before carrying out voltage measurements, observe the
following:
•
Never apply a voltage exceeding the rated nominal voltage
of the measuring device between the connections or
between the connections and earth (see imprint on the
housing).
•
Check the measuring tips for damaged insulation and for
continuity. Replace damaged measuring tips.
•
Check the insulation of the measuring device sockets.
•
Before commissioning, check the function of the device at
a known voltage source, e.g. on a known and safe 230 V
voltage source or on a known and safe 9 V battery.
•
First connect the measuring tip connected to earth and
afterwards the live measuring tip. When disconnecting the
measuring tips, proceed in reverse order, i.e. disconnect
the live measuring tip first.
•
Prior to every voltage measurement make sure that the
measuring device is not set to the current measuring
range.
•
If the device indicates an exceedance of the measuring
range (
OL
) immediately after being connected to the
measuring object, first switch off the circuit at the
measuring object, then immediately remove the measuring
tips from the measuring object.
•
Do not switch any motors in the measuring circuit on or off
during a measurement. Voltage peaks caused by a
switch-on or switch-off can damage the measuring device.
