discharged before connecting to the measuring
terminals.
When testing large capacity capacitors, please pay
attention to the delay before the meter gives a final
reading.
Do not connect a charged capacitor to the measuring
terminals!
When testing ≤1μF low capacitance capacitors, to
ensure the accuracy of measurement, press "REL"
before carrying out the measurement.
3.3.7. FREQUENCY AND DUTY CYCLE
1 )
Turn the dial to „Hz".
2)
Connect the black test lead to the "COMT-" terminal

beep will sound.
Please Note: Although the meter may not indicate
voltage in the conductor, there is a risk that the
conductor may be live. The voltage detection
operation depends on the design of the conductor,
thickness of the insulation, etc.

Protect the device from dust and dirt.
l)
Use only new batteries of the size and type indicated
in the technical specifications. Before installing or
replacing the batteries, make sure that the device is
not connected to an external circuit, that the control
knob is set to "OFF", and that the test leads are
disconnected from the terminals.
m)
Before installing or replacing the batteries, make
sure that the device is not connected to an external
circuit and that it is turned off.
