Resistance Measurements - Klein Tools MM300 Manuel D'instructions

RESISTANCE MEASUREMENTS

1. Insert RED test lead into V jack
into COM jack
highest Ω setting (2MΩ).
2. Remove power from circuit.
3. Measure resistance by connecting test leads to circuit and
rotating the function selector switch
lower Ω settings to obtain higher resolution measurements.
Black lead
NOTE: When in a Resistance setting and the test leads are open
(not connected across a resistor), or when a failed resistor is under
test, the display will indicate O.L. This is normal.
DO NOT attempt to measure resistance on a live circuit.
CONTINUITY
1. Insert RED test lead into V jack
jack , and rotate function selector switch

2. Remove power from circuit.
3. Test for continuity by connecting conductor or circuit with test
leads. If resistance is measured less than 100Ω, an audible
signal will sound and display will show a resistance value
indicating continuity. If circuit is open, display will show "OL".
Black lead
DO NOT attempt to measure continuity on a live circuit.
