5.3 OHM AND LOW VOLTAGE OHM MEASUREMENTS

* Set dial.

* Choose

Ω

or LV

Ω

*Connect leads

*

CAUTION

:

Remove all power from the circuit before connecting the test

leads.

* LV setting reduces the maximum test voltage level to about 0.5V to avoid turning
on semiconductor devices.
* Remove individual components from circuitry for best results.
