Input sockets
COM
common socket for all quantities to be measured and transistor
testing (COM) (negative)
voltage, resistance, capacity, frequency, duty factor and diode
tester input (positive)
current (0 – 400 mA), transistor tester (IN) input (positive)
10 A
current (400 mA – 10 A) input (positive)
Accuracy
Accuracy is ensured for one year after calibration, at an operating tempera-
ture of 18 °C – 28 °C and a relative humidity of 0% – 75%.
FEATURES
Battery saver function
In order to conserve power, the multimeter automatically switches off after
approx. 15 minutes if no measurement is performed or function is changed.
This is indicated by 5 short beeps 1 minute before switching off then the unit
switches off with a beep.
Contact free phase detection (NCV)
Set the dial to the “NCV” position. If the multimeter’s front (indicated by 1 in
figure) is brought close to a live conductor, the multimeter’s light (indicated
by 2 in figure) and buzzer will activate. Precondition for activation: voltage
exceeding 110 V AC RMS.
Note: Do not rely solely on the instrument, as dangerous voltage may still
be present in the conductor being tested even if there is no indication. De
-
tection can depend on the type of socket, the thickness of insulation, RF
interference and other factors, which can falsify the measurement.
DC voltage measurement (
)
Connect the red probe cable to the
socket, and the black one to the
“COM” socket. Set the dial to the DC voltage position. Connect the mea
-
surement probes to the circuit to be measured.
Note: The reading can be unstable, especially in the 400 mV measurement
range, if the probe cable is not connected to the circuit being measured.

Overload protection: The F400 mA / 1000 V fuse is at the
socket
while the F10A/500 V fuse is at the “10A” socket.
Max input current:
socket: 400 mA DC or AC RMS; at “10A” socket:
10A DC or AC RMS If the measured current is greater than 5 A, the duration
of continuous measurement should not exceed 10 seconds, and at least 1
minute should elapse between two measurements.
Measurement of AC voltage (
)
Connect the red probe cable to the
socket, and the black one to the
“COM” socket. Set the dial to the AC voltage position. Connect the mea
-
surement probes to the circuit to be measured. Note: The reading can be
unstable, especially in the 400 mV measurement range, if the probe cable is

Frequency measurement
Connect the red probe cable to the
socket, and the black one to the
“COM” socket. Set the dial to the “Hz%” measurement range. Use the “Hz/
DUTY” pushbutton to set the frequency (Hz) function. Connect the mea

Note: Frequency measurement only works with automatic measurement
range selection. Do not exceed the input voltage as this will damage the
instrument.
