Insulation Testing - Maxwell Digital Multimeters 25601 Gebrauchsanleitung

connectors. These have overload protection
to the limits specified in the manual. When
measuring, connect the black wire to the
'COM' connector and the red one to the 'VΩ'
connector.

Current measuring
• Set the function switch to the appropriate AC A
threshold. Place the clamps onto the cable with
the AC current.
• If there is only a '1' on the screen, it signals
an overload, you need to switch to a higher
threshold.

Insulation testing

• Connect the wires of the insulation tester ('VΩ' ,
'COM' , 'EXT')to the 'VΩ' , 'COM' , 'EXT' connectors of
the clamp meter.
• Set the function switch to the 2000 MΩ position.
• Set the threshold to the 2000 MΩ position
• Connect the measuring arms to the 'L' and 'E'
connectors. The tester has to be turned off when
connecting.
• Turn the 'POWER' switch of the insulation meter
on.
• Press the PUSH 500V button, and the red 500V
lamp will light up. The value of the measured
insulation resistance is displayed on the screen.
If the measured value is below 19 MΩ, set the
clamp meter to 20 MΩ.
• If you do not use the insulation meter, turn it
off and remove the wires from the 'E' and 'L'
connectors. This saves battery life and reduces
the risk of electric shock.

INCLUDED)
Voltage measuring
Connect the red wire to the 'VΩ' connector and the
black one to the 'COM' connector.
Set the function switch to the proper AC V or DC
V setting.
Connect to the measured circuit. The measured
value is displayed on the screen. (In case of DC
voltage measuring the polarity of the red wire is
displayed as well).
If there is only a '1' on the screen, it signals an
overload, you need to select a higher threshold.
Resistance measuring
• Connect the red wire to the 'VΩ' connector and
the black one 'COM' connector. (The polarity of
the red wire '+').
• Set the function switch to the proper resistance
function.
• Touch the measuring wires to the resistor and
read the value on the screen.
• If the resistance is higher than the maximum
value of the selected threshold, '1' appears on
the screen.
• If the resistor is part of a circuit, turn off the
power and discharge every high capacity
capacitors before connecting
Continuity test
• Connect the red wire to the 'VΩ' connector and
the black one to the 'COM' connector.
• Set the function switch to „ " position.
• Connect the wires to the measured circuit. If the
circuit is not broken (R< 50Ω), the device will
beep.
