9. 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.
AC (TRUE RMS)/DC VOLTAGE MEASUREMENT

Connect the red test lead to the V·Ω·CAP·TEMP·HZ jack [11] and the
black lead to the COM jack [10] .

Set the rotary function switch [3] in the position.

Use the mode button [5] to choose between AC and DC voltage.

Connect the test leads parallel to the source being measured.

Read the voltage value on the LCD display [9] along with the polarity of
the red lead connection.

For AC measurement, press the peak hold button [6] to hold either
maximum or minimum measured value (see Peak hold function ).
