SEL button
[11]
Used for zeroing DC current measurements (ZERO in
the display).
Moreover used to switch between various functions,
e.g. Ω, continuity.
A brief beep confirms pressing of the button.
MIN/MAX button
Press the MIN/MAX button once or more to dis-
■
play the maximum or minimum measured value
as a value or the difference between the two.
RAN button
[9]
Press the RAN button to switch between auto-
■
range and manual range switching.
Hz/% button
(in the A or V measuring range)
To switch between Hz and duty cycle measurement.
The duty cycle equals, for a square wave signal, the
ratio of the length of the switched on state (pulse
duration) to the period duration (pulse width mod-
ulation). The duty cycle is specified as a dimension-
less ratio with a value between 0 and 1, or 0 and
100 %.
B.L. / HOLD button
Press the B.L./HOLD button to freeze the cur-
■
rently displayed value.
3 Press and hold the B.L./HOLD button to switch
on the backlight.
3 If set in the measuring range, the measuring point
illumination is also switched on.
Transducer clamp jaws
Record the current flowing through the cable.
Note the markings + and - on the current jaws,
■
to determine the current direction (direct current
measurement only).
Open the clamp jaws.
■
Enclose a cable.
■
Ensure the jaws close correctly.
■
There must not be any foreign bodies in the
■
connecting gap.
Connections
Input [6]:Input for the red test lead for voltage,
resistance and continuity measurements.
COM [7]:Common input for the black test lead for
voltage, resistance and continuity measurements.
If the set value is exceeded over a long period by
the steady current being measured, heating can
occur, which can impair the operating and functional
safety of internal circuits.
