To carry out a correct resistance measurement with 3 wires, the 3 conductors used must be:
of the same length,
of the same diameter,
of the same type of metal.
The MC 75.2 displays an icon showing the connections used (
for 2 wire,
for 3 wire
or
4 wire) to make the measurement. The wiring arrangement is automatically detected
by the calibrator.
2.2.4
Continuity test
•
Display the
MEASUREMENT CONFIGURATION
dialogue box.
•
Select the
Continuity
measurement function using the
function and navigation keys.
•
Confirm with ENTER.
The MC 75.2 makes a resistance measurement in this mode
and displays “open” if the resistance measured is greater
than 1000
Ω and
“closed” if the resistance measured is less
than 1000
Ω.
