5 On / Off
To switch on the device, turn the rotary switch to the desired measuring function. The meter will
power on immediately. To turn off the meter, turn the rotary function switch to “OFF”. The meter
will switch off automatically.
6 Measuring functions
6.1 µA measurement
To make a µA measurement, turn the rotary switch to “µA“. Use the input jacks “COM“ and “V, Ω,
HZ, %, mA, …“. With the “MODE“ key, you can switch between alternating and direct current.
6.2 mA measurement
To make a mA measurement, turn the rotary switch to “mA“. Use the input jacks “COM“ and “V,
Ω, HZ, %, mA, …“. With the “MODE“ key, you can switch between alternating and direct current.
6.3 10 A measurement
To make a measurement up to 10 A, turn the rotary switch to “10 A“. With the “MODE“ key, you
can switch between alternating and direct current.
6.4 Alternating voltage, frequency and duty cycle measurement
To measure voltage, frequency or the duty cycle in an alternating voltage, turn the rotary switch
to “V, Hz, %“. Now connect the test leads to the input jacks „COM“ and „V, Ω, HZ, %, mA, …“.
With the “MODE“ key, you can now switch between voltage, frequency and duty cycle
measurement.
6.5 Direct voltage measurement
To make a DC voltage measurement, turn the rotary switch to “V“. Use the input jacks „COM“ and
„V, Ω, HZ, %, mA, …“. With the “MODE“ key, you can switch between alternating and direct
current.
6.6 Resistance measurement / diode test / continuity test / capacity measurement
To make a resistance measurement / diode test / continuity test / capacity measurement, turn the
rotary switch to „Ω, CAP, ...“. Then select the desired measuring function with the “MODE“ key.
Now connect your test object to “COM“ and „V, Ω, HZ, %, mA, …“. The reading will be displayed
directly.
NOTE: To determine the capacitance of a capacitor, you must make sure it is discharged before
making the measurement. The capacitor will be charged during the measurement.

6.6.1 Diode test
To test diodes, touch the diode with the test leads and write down the reading that is displayed.
Now change the polarity and compare the new reading with the first reading. If “OL“ is displayed
during both measurements, the diode is defective. If the reading for the first measurement is “OL“
and the value for the second measurement is a typical value between, e. g. 0.400 and 1,800 V,
this means that the diode works. If voltage values are displayed for both measurements, this
means that the diode is defective. In this case, the diode will cause a short circuit.
6.7 Temperature measurement
To make a temperature measurement, turn the rotary switch to “TEMP“. Then connect the
thermocouple adaptor to the meter as follows:
Black –into “COM“ jack
Red + into ”V“ jack
Then connect the thermocouple via the adaptor. Make sure the polarity is correct. The reading
will be displayed directly and will stabilise after approx. 30 seconds.
You can switch between °C and °F by using the “MODE“ key.
7 Hold readings
To hold / freeze the currently displayed reading, press the “HOLD / backlight“ key. The icon
will appear in the display. If you press the “HOLD / backlight“ key again, the held reading will be
released and the current measurement will be continued.
8 Backlight
To activate the backlight, press and hold the “HOLD / backlight“ for three seconds. The backlight
will turn on immediately. To deactivate the backlight, press and hold the same button for three
seconds again.
NOTE: The backlight will turn off automatically after 5 minutes.
9 MAX/MIN recording
Recording is started by pressing the „MAX/MIN/Range“ key. This will be indicated by the
„MAX/MIN“ icon in the display. During this type of recording, onlythe highest and thelowest value
will be saved and displayed. All other readings will be lost. Now press the „MAX/MIN/Range“ key
to switch between MIN and MAX. Tor e-enter normal measurement mode, press and hold the
„MAX/MIN/Range“ key for three seconds. The saved data will be lost when you do this.
NOTE: This function is only available if Auto Range is activated.
10 Select measurement range
To select the measurement range, press and hold the “MAX/MIN/Range”key for three seconds
to deactivate Auto Range. Press the “MAX/MIN/Range“again several times until you have
reached your desired measurement range. To re-activate Auto Range, press and hold the
“MAX/MIN/Range” key again for three seconds.

11 Bluetooth and flashlight
To switch on the flashlight, press and release the “Bluetooth / flashlight“ key. Press the same
button again to switch it off again.
To activate Bluetooth, press and hold the “Bluetooth / flashlight“ key for several seconds. The
icon will appear in the display. To turn off Bluetooth, press and hold the “Bluetooth / flashlight“
key again for several seconds
Use the “Meterbox Pro“ app from your Android or iOS store to connect the device to your mobile
phone.
12 Auto Power Off
To increase the battery life, the meter will switch off automatically after 15 minutes of inactivity.
To switch on the device after this, turn the rotary switch to “OFF“ and then turn it to your desired
measurement mode. To deactivate Auto Power Off, press and hold the “MODE“ key and switch
on the device. Then release the “MODE“ key. Auto Power Off is now deactivated.
13 Batteries
When the battery is no longer sufficiently charged, the following icon will appear on the display:
. In this case, replace both 1.5 V AAA batteries. If you do not replace the batteries,
measurement errors and even failure of the device can occur.
To replace the batteries, open the battery compartment on the rear side of the meter by loosening
the screw of the cover with a screwdriver. Observe correct polarity wehn replacing the batteries
and screw the battery compartment cover back on.
14 Fuse replacement
To replace the fuse, open the fuse compartment which is located below the foldable stand on the
rear side of the meter. Pull out the fuse and replace it by a newone. Only use the following fuses:
F10 A/600 V and F600 mA/600 V.
Follow the instructions in the fuse compartment for the correct arrangement of the fuses.
NOTE: Disconnect all test leads and turn off the meter before replacing the fuses.
