AC current measurement / A~
Use the selector switch to set the appropriate range. Connect the black test lead into the "COM"
socket, and the red test lead with the mA / 10A socket (the appropriate socket opens automatical-
ly depending on the measuring range). Using the test probes, touch the test points of the test ob-
ject. Read measurement value on the display.
You must use the ‘10 A’ socket when measuring currents above 200 mA.

Overload protection: mA range is protected with a 200 mA self-resetting fuse.
- 10A range is protected with F 10 A / 1000 V.
- In the 10A range observe the maximum operating times!
- Frequency range: 40-400 Hz
*To protect against overheating, measurements should not be taken for more than
10 seconds. Following this the device should be allowed to cool down for at least
15 minutes.
Capacitance measurement / F
Use the selector switch to set the appropriate range. Insert the black test lead into the ‘COM’
socket and the red test lead into the V/Ω/TEMP/CAP socket. Using the test probes, touch the test
points of the test object. Read measurement value on the display.
