E. DC CURRENT MEASUREMENT (AMPS)
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 15 seconds to take the reading. A
waiting period of AT LEAST 15 MINUTES is necessary
between every 15 second testing period.
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 9 and 10).
•
To measure from 0 to 200mA, set the Selector Switch to
the desired "DCmA" position.
•
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.
NOTE: To measure current on a particular circuit, you
must open up the circuit and connect the test leads in
series with the circuit before a reading can be obtained.
4. Disconnect one end of the wire or device, from the circuit
where current will be measured.
5. Place the RED test lead on the disconnected wire and place
the BLACK test lead at the location from which the wire was
disconnected (series connection).
6. Reconnect the battery, or apply power to the circuit being
tested.
7. Read the results on the display.
CAUTION: After the test is completed, shut the
power off to the circuit before removing the test
leads and before reconnecting any disconnected
wires or devices.
NOTE: If the reading obtained is a negative number,
reverse the test leads.
