Resistance Measurements - Klein Tools MM400 Manuel D'instructions

ENGLISH
2. To measure current: Remove power from circuit, open circuit at
measurement point, connect meter in-series in the circuit using
the test leads, and apply power to circuit.
3. Measure the current. The meter will auto-range to display the
measurement in the most appropriate range.
Do not attempt to measure more than 10A.
When measuring currents greater than 6A, a measurement
time of 30 seconds followed by 10 minutes of recovery time
is recommended.

RESISTANCE MEASUREMENTS

1. Insert RED test lead into V jack
into COM jack
Continuity/Resistance
NOTE: The meter defaults to Continuity testing in this mode. To
enter Resistance testing mode, press the "SEL" button
The Resistance icon will appear on the display.
2. Remove power from circuit.
3. Measure resistance by connecting test leads to circuit. The
meter will auto-range to display the measurement in the most
appropriate range.
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.
