• Avoid 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.

6. 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 ±20 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
H -symbol in the display.
• To switch on the backlight, press the backlight button [8], to switch it off, press the
backlight button [8] again. The use of backlight will reduce battery life.
• Peak hold function: for AC measurements, pressing the peak hold button [6] once will
show only the maximum measured value on the display [9], indicated with a P MAX
indicator. Pressing the peak hold button [6] again will show only the minimum measured
value on the display [9], indicated with a P
MIN indicator. To exit the peak hold function,
press and hold the peak hold button [6] for ±3 seconds until the P MAX or P MIN indicator
disappears.
