Resistance measurements
WARNING:
To avoid electric shock, disconnect power to the unit under
test and discharge all capacitors before taking any
resistance measurements. Remove the batteries and unplug
the line cords.
In order to realise a measurement of the resistance it is
necessary to realise the following actions:
•
Set the function switch to the
Ω
CAP position,
•
Insert the black test lead banana plug into the negative COM
jack. Insert the red test lead banana plug into the positive
V
Ω
TEMPHz%mA
µ
A jack,
•
Press the MODE button to indicate “

”
on the display,
•
With the RANGE button set the measurement range manually
if necessary,
•
Touch the test probe tips across the circuit or part under test. It
is best to disconnect one side of the part under test so the rest
of the circuit will not interfere with the resistance reading,
•
Read the resistance in the display.

Continuity Measurements
WARNING:
To avoid electric shock, never measure continuity on
circuits or wires that have voltage on them.
In order to realise continuity test it is necessary to realise the
following actions:
•
Set the function switch to the
Ω
CAP position,
•
Insert the black test lead banana plug into the negative COM
jack. Insert the red test lead banana plug into the positive
V
