5.3 Resistance measurement
1. Connect the black test lead
to
and the red test
lead to
or use
the multi-purpose socket*
(if you are measuring loose
components).
2. Set the function selector
to the resistance
measurement .
3. Connect the test leads
across the circuit to
be tested.
*The multi-purpose socket should be connected to
and
.
Warning:
Ensure that the circuit to be tested is not “live”, before taking any
measurements. In order to avoid the risk of personal injury, never measure
components with a voltage higher than 60 V (DC) or 30 V (AC).
Note:
• The test leads can add 0.2–0.5 Ω of error to the actual resistance measured.
To obtain accurate readings of low-resistance components, press
[ REL
▲
/RS 232 (USB) ] and short-circuit the input sockets beforehand,
to remove the lead resistance error from the reading on the display.
• If the Ω reading with shorted test leads is ≤ 0.5 Ω, check that none of the test
leads or connections is loose.
• For high-resistance measurement (>1 MΩ) it is normal that it takes several seconds
for the reading to stabilize. Use test leads which are as short as possible or use
the multi-purpose socket to carry out the measurement.
• If
appears on the display, the tested resistance is either open-circuit or higher
than the maximum range of the meter.
