RESISTANCE MEASUREMENTS
Figure 6. Resistance Measurements
WARNING
Voltage applied to resistance range will cause reading errors if low and damage the
Instrument if high. When making in-circuit measurements, make certain that the circuit is
completely de-energized before making connections to it.
When making in-circuit measurements, circuit paths in parallel with the resistance being
measured may cause reading errors. Check circuit diagrams for the presence of such
components before assuming that the reading obtained is correct.
Branch and distribution circuits (120/240/480V etc.) can deliver dangerous explosive power
momentarily into a short circuit before the fuse/breaker opens the circuit. Make absolutely
certain that the Instrument switches are set properly, jacks are connected properly, and that
the circuit power is turned off before making connections to such circuits.
