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 ±30
minutes. 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.

Light measurement
•Set the rotary switch [3] to the Lux- or Lux 10x-position.
•Point the light sensor [9] towards the light source for more accurate
measurement. The light level will be displayed [7].
Note: sensor calibrated to standard incandescent lamp @ 2856K
Room temperature
•Set the rotary switch [3] to any position (except OFF).
•The room temperature at the current location is measured ([1]) and the
value is shown on the top line of the LCD [2].
Thermocouple temperature
•Set the rotary switch [3] in the °C or °F position.Do not apply input
voltage at this setting!
•Insert the thermocouple adaptor into the temp input [4] and COM input
[5].
•Plug the thermocouple itself into the adaptor (if not done yet). There is
only one way possible, do not force.
•Use the other end of the thermocouple to measure temperatures.
Temperature is shown on the LCD [5].
Notes:
•do not expose the multi-meter itself to temperatures lower than 0°C
(32°F) or higher than 40°C (104°F).
•Do not change the probe, as this will influence measuring accuracy.
AC/DC voltage measurement
•Connect the red test lead to the V input jack [4] and the black lead to
the COM input jack [5].
•Set the rotary switch [3] in the desired position (V , V , mV ). If
the voltage to be measured is unknown beforehand, set the range switch
in the highest range position and then reduce gradually until the ideal
resolution is obtained.
•Use the mode button [13] to choose between AC and DC voltage.
•Connect the test leads to the source being measured.
•Read the voltage value on the LCD display [2]along with the polarity of

10A [7] input jack and the black test lead to the COM jack [5].
•Set the rotary switch [3] in the desired current range (<4mA: µA ,
<400mA: mA , <10A: 10A ) and use the mode button [3] to
choose between AC and DC current.
•Open the circuit in which the current is to be measured and connect the
test leads to the circuit IN SERIES.
•Read the current value and the polarity of the red lead connection on the
LCD display.

Resistance, diode test and audible continuity test
•Connect the red test lead to the Ω-jack [4] and the black test lead to the
COM jack [5](the red lead has a positive polarity "+").
•Set the rotary switch [3] in the Ωrange position. Do not apply input
voltage at this setting!
•Use the mode button [13] to choose between Ω, diode or continuity test.
•If the resistance being measured is connected to a circuit, turn off the
power and discharge all capacitors before applying the test probes.
•Connect the test leads to the resistor to be measured and read the LCD
display.

•For diode tests, connect the red test lead to the anode of the diode to be
tested and the black test lead to the cathode of the diode. The approx.
forward voltage drop of the diode will be displayed (typically 0.400 –
0.700V). If the connection is reversed, the display will show “OL”.

•For continuity tests, connect the test leads to two points of the circuit to
be tested. If continuity exists (resistance < 50Ω), the built-in buzzer will
sound. If the circuit is open, “OL” will be indicated.
Non-contact AC voltage test
•Set the rotary switch [3] to any position (except OFF).
•The AC-sensor is located at the top of the meter, near the light sensor
[9]. Point the AC-sensor towards the suspected AC-source. When AC
voltage is present, the indicator [16] will light up. The stronger the AC-
source, the more the indicator [16] will be lit.
7. Battery
•When the low battery indication ( ) appears, replace the internal
batteries. Turn the rotary switch [3] to the OFF-position.
•Always disconnect test leads when replacing the battery. Do not us the
device without batteries installed.
•The battery cover is located on the back of the device and is closed with two
screws. Remove the screws and open the battery compartment.
•Remove the battery and insert a new 9V (E-block) battery following the
polarity as indicated in the battery holder.
•Reinstall the cover and secure it with the two screws.
•Remove the battery when the device is not in use for a longer period of time to
avoid leakage.
•Do not attempt to recharge non-rechargeable batteries, do not puncture and do
not throw in fire as they may explode.
WARNING: handle batteries with care, observe warnings on
battery casing. Dispose of batteries in accordance with local
regulations.
Keep batteries away from children.
8. Fuses
•To replace an internal fuse, turn the rotary switch [3] to the OFF-position.
•Always disconnect test leads when replacing fuses.Do not use the device
without the proper fuses installed.
•The access the fuses, the whole back cover must be removed. Loosen the 6
outer screws (2 are located under the foldable stand). Do not remove the
battery cover screws (see §7). Lift the whole back cover. Do not touch the
electronic circuitry inside.
•Replace fuses only by new ones with following specifications:
•Fuse 1 (large): F 10A/600V fast blow
•Fuse 2 (small): F 500mA/660V fast blow
Using wrong fuses or short-circuiting fuse holders can lead to
potentially life-threatening situations.
•Close the back cover and secure the 6 screws.
