9 light sensor
long life silicon light sensor diode
10 Hz/% button
switch to Hz/% measurement – available when measuring AC/DC
voltage, AC/DC current and Hz/%
11 hold/backlight button
Freeze/unfreeze all values on the display. Press and hold for ±3s to
switch backlight on/off.
12 °C/°F mode button
Switch room temperature reading between °C and °F
13 mode button
Switch between AC and DC current measurement; switch between Ω,
diode and continuity test.
14 range button
Select displayed measurement range manually.
15 REL button
Press to store the current measuring result and start measuring against
this value. Press again to exit relative measurement mode.
16 Non-Contact Voltage (NCV) indicator
turns on when the built-in non-contact AC voltage detector detects AC
voltages
6.
Use
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 500mA (mA/µA
jack [6]) or 10 A (10A jack [7]). Note that the meter can only handle
10A for less than 30 seconds (with 15 minutes cool-down time).
• The device will go in sleep mode when no activity is detected for ±15
seconds. Press any button to re-activate.
Sound level measurement
• Set the rotary switch [3] to the dBC-position.
• Point the microphone [8] towards the sound source for more accurate
measurement. The sound level will be displayed.
Note: strong wind (over 10m/s) will have a negative impact on the
measurement.
Humidity measurement
• Set the rotary switch [3] to any position (except OFF).
• The relative humidity at the current location is measured ([1]) and the
value is shown on the top line of the LCD [2]. For more accurate results,
let the multimeter acclimatize for ±2h before measuring.
