15
To measure from 0 to 400mA, set the Selector Switch to
.
To measure from 400mA to 15 Amps DC, set the
Selector Switch to the "
15A
" 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.
J. CLAMP CURRENT MEASUREMENT
NOTE:
Clamp current measurement requires use of an optional
Clamp adapter. The optional Clamp adapter has not been
evaluated by UL.
1.
Plug the RED test lead from the Clamp adapter to the
jack of the tester; plug the BLACK test lead into the
"
COM
" jack.
2.
Set the tester’s Function/Range Selector Switch to the
position (see Controls and Indicators, Item 11).
3.
Clamp the Clamp adapter around the wire or cable from the
source or load under measurement.
4.
Read the results on the display.
K. COP RPM AND RPM (TACH) MEASUREMENT
WARNING
