body contact with ground potential (e.g. metallic terminals, output
sockets, lead clamp…) while measuring. Make sure to be electrically
insulated from ground during measurement.
•
Calibration and repair must be performed by a qualified technician. Refer to
your local dealer.

Operation
GENERAL
•
When the range of the measured signal is unknown, start measurement
in auto-range mode, and then select range according to indicated value.
•
The display shows “OL” when the present range limit is exceeded. Select
a higher range to continue measurement.
•
Do not
measure voltages > 600 V or current higher than 1000A.
Never
turn the rotary function switch
[3]
during measurement.
•
The device will go in sleep mode when no activity is detected for ±30
min.
•
For all measurements: pressing the data hold button
[4]
freezes the
currently measured value until the data hold button
[4]
is pressed again.
The hold-mode is indicated by the word “HOLD” in the display.
•
To switch on the backlight, press and hold the backlight button
[4]
for
about one second. To switch the backlight off, press and hold the
backlight button
[4]
again for ±1s. Note that the meter goes in HOLD
mode when switching the backlight on or off. Press the data hold button
[4]
again to continue normal measurement.
•
The meter starts in auto ranging mode. To select the range manually,
press the range button
[7]
(not for
AC current, diode and continuity
measurements). To return to auto ranging, press and hold the range
button
[7]
for ±2 seconds.
