2
(data hold) button = captures the measured value.
3
Holding/switching through the measurement ranges = manual
range selection
4
Rotary switch (= measuring function switch) for setting the

ment, etc.).
5
20 A input
This measuring input is protected with a 20 A fuse and is suita-
ble for DC and AC currents up to max. 20 A (max. 30 s durati-
on with 15 minute pause between measurements).
6
This input is for measuring DC and AC currents up to 400 mA
max. (protected with a quick-blow 800mA fuse)
7
COM (0) input socket (COM or negative connection)
8
V-Ohm-(+) input socket (= positive connection)
Multifunction LCD display

10
Bar graph sub-graduations
11
Overload display
12
When "OL" appears in the display and an acoustic signal so-
unds, this means overflow = range exceeded (no acoustic sig-
