point before changing the measuring range.
Note
To prevent damages to the device, do not expose it to
extreme temperatures, extreme humidity or moisture.
Note
Do not use abrasive cleaners or solvents to clean the
device.

safe230V voltage source or on a known and safe
9Vbattery. Select the correct measuring range!
Information about the device
Device description
Using the clamp meterBE40 you can easily measure the
amperage of alternating currents, ACand DCvoltages as well as
resistances.
Furthermore, you can check the continuity of circuits, fuses and
contacts and test the forward voltage of diodes without the need
for contact.
The current measurement is effected without contact via the
electromagnetic field, which is why the electric circuit doesn't
have to be interrupted for this method. Therefore, running
systems, which cannot be switched off separately, can also be
checked.
Owing to the galvanic isolation, the measuring signal is also
potential-free towards the variable to be measured.
