place it into the proper connector (this connector is
included and connects to the mA + COM connectors).
•
The transistor's amplification
factor is displayed on the screen.
I = 15 μA, V = 1,5 VBC
Frequency measurement
•
Connect the measuring wire or shielded cable to the
„COM” and „VΩHz” connectors.
•
Set the function switch to „Hz” and touch the wires to
the signal source.
Note:
•
Do not measure frequency on higher voltage than
250V(RMS)
•
In a noisy environment it is recommended to use
a shielded wire when measuring weak signals.
•
Avoid touching the circuit when measuring high
voltage.
•
Range selection is always automatic when
measuring frequency.
Duty cycle measurement
Set the function selection switch to "Hz" and press the
"SELECT" button once to measure duty cycle.
Data hold and backlight function
By pressing the HOLD button the actual measured
value gets held on the screen until the button is
pressed again.
Press long the „HOLD” button to backlight on. The
backlight automatically off after 15sec.
Warning
•
When measuring voltage make sure that the
wires do not connect to the current measurement
connector and the function switch is not in a
resistance or diode measurement position.
Always make sure that the wires are connected to
the proper connector.
•
Take care when measuring voltage above 50V,
especially with high power devices.
•
Avoid connecting to 'live' circuits.
•
When measuring current make sure the circuit
is not under voltage before connecting the
multimeter.
•
Before measuring resistance and diode make
sure the power is disconnected for the time of
measuring.
•
Always use the proper function and measuring
range. If you are unsure about the range, select
the highest available and move backwards from
that.
•
Make sure that the measuring wires and their
insulation are intact.
•
Be careful, do not go over the specified overload
thresholds.
•
Only replace fuses to those of the same type and
value.
•
When opening the lid of the device for replacing
fuses or batteries make sure that all external
power sources are disconnected and the function
switch is in OFF state.

Handling
•
Keep the multimeter dry at all times. If it becomes
wet, wipe it immediately. Liquid may corrode the
circuits.
•
The multimeter may be stored and operated only at
normal temperatures. High temperatures reduce the
lifetime of electric devices, damages the batteries
and distorts/melts the plastic parts.
•
Handle the multimeter with care. Dropping it may
result in damage to the circuits and the surface which
may cause improper functioning.
•
Protect the multimeter from dust and other dirt
which may cause the untimely wearing of the parts.
•
Clean the multimeter with a wet cloth. Do not
use chemicals, solvents or strong detergents for
cleaning.
Maintenance
•
Battery replacement (9 V)
•
Disconnect all external circuits from the device. Turn
it off and remove all measuring wires.
•
Unscrew the bottom lid.
•
Remove the depleted battery and replace to one of
the same type.
Fuse replacement
•
Disconnect all external circuits from the device. Turn
it off and remove all measuring wires.
•
Unscrew the bottom lid.
•
Remove the melted fuse and replace to one of the
same type and value.
