I. AC/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 15A 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 15 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.
1. Plug the RED test lead into the
the tester, as applicab le; plug the BLA CK test lead to the
"COM" jack.
2. Set the tester' s Function/Range Selector Switch to the
appropriate Amps range position as desired (see Controls
and Indicators, Items 9 and 10).
•
Use the SEL button (see Controls and Indicators , item
20) to select DC Amps or A C Amps, as desired.
•
To measure from 0 to 400mA, set the Selector Switch to
•
To measure from 400mA to 15 Amps DC
Selector Switch to the "15A" position.
3. Disconnect the batter y, or shut off the po wer 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 de vice, 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 batter y, or apply po wer 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 recon-
necting any disconnected wires or devices.
NOTE: If the reading obtained is a negative number, reverse the
test leads.
