D. CONTINUITY TEST
1.
Plug the RED test lead into the
jack of the multimeter;
plug the BLACK test lead into the "COM" jack.
2.
Set the meter’s Function/Range Selector Switch to the
position (see Controls and Indicators, Item 6).
3.
Place the RED Test Lead to one end of the wire or device
being tested for continuity and the BLACK Test Lead to the
opposite end.
4.
Listen to the sound of the beeper and confirm the results by
reading the display.
NOTE: The beeper will sound only if the continuity of the item
under test (resistance between the two test leads) measures
less than 120 ohms.
E. AC/DC CURRENT MEASUREMENT (AMPS)
1.
Plug the RED test lead into the "mA" or the "DC10A" jack of
the multimeter, as applicable; plug the BLACK test lead to
the "COM" jack.
2.
Set the meter's Function/Range Selector Switch to the
appropriate Amps range position as desired (see Controls
and Indicators, Items 4, 10 and 11).
•
To measure from 0 to 200mA, set the Selector Switch to
the "DCmA" or "ACmA" position, as applicable.
•
To measure from 200mA to 10 Amps DC, set the
Selector Switch to the "DC10A" position.
3.
Disconnect the battery, or shut off the power to the circuit
being tested.

WARNING
To prevent electrical shock when performing current
measurements, follow all steps as indicated below DO
NOT skip any steps or take any short cuts.
The DC10A range is not fused. To avoid current hazard
and/or damage to the tester, DO NOT try to take meas-
urements on circuits that have more than 10 amps. DO
NOT take more than 10 seconds to take the reading. A
waiting period of AT LEAST 15 MINUTES is necessary
between every 15 second testing period.

WARNING
To avoid electric shock, shut off the power to the test arti-
cle before testing it for continuity.
