DC/AC voltage measurement
1.
Set the measuring function selector to DC/AC (1000 V DC or 750 V AC).
2.
Plug the black test lead into the negative COM port.
3.
Plug the red test lead into the positive port V.
4.
Contact the tip of the black test lead with the negative side of the circuit.
5.
Contact the tip of the red test lead with the positive side of the circuit.
6.
Read the voltage value in the display.
Note:
If the polarity is reversed, there is a minus sign in front of the measured value.
Resistance measurement
Warning:
To avoid electric shock, check that the circuit or electrical component is
voltage-free before starting the measurement.
1.
Set the measuring function selector
to 200 kΩ.
2.
Plug the black test lead into the negative COM port.
3.
Plug the red test lead into the positive port
Ω.
4.
Contact the tips of the test leads with the component/circuit to be tested.
5.
Read the resistance value in the display.
„HOLD“ function
The "HOLD" function "freezes" the measured value on the display. Press the "HOLD" key at the
desired moment to capture a displayed reading. Pressing again terminates the function.
Backlight
Press
to enable the display backlight. The backlight will switch off automatically after 15
seconds.

Maintenance and cleaning
6.1
Battery replacement
A low battery level is indicated by the

Warning
: Before opening the earth resistance tester, disconnect it from the
measuring circuit, remove the test leads from the meter and carefully remove
the fold-down device stand.
To insert the batteries when restarting or to replace the batteries with insufficient voltage, loosen
the four screws of the battery compartment cover on the back of the device, remove the lid, insert
the batteries or remove the old batteries, replace them with new ones, insert the lid and screw it
back in.
