J. CLAMP CURRENT MEASUREMENT
NOTE: Clamp current measurement requires use of an optional
Clamp adapter. The optional Clamp adapter has not been eval-
uated 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. BATTERY TEST
1. Plug the RED test lead into the "BAT." jack of the tester;
plug
the BLACK test lead into the "COM" jack.
2. Determine the voltage rating of the battery to be tested.
3. Set the tester’s Function/Range Selector Switch to the
desired "Battery Test" position (see Controls and
Indicators, Item 12).
4. Place the RED test lead on the positive (+) post of the bat-

WARNING
Risk of Explosion. This equipment has internal arcing and
sparking parts, which should not be exposed to flammable
vapors. This equipment is only suitable for installation in a
garage having sufficient air circulation to be considered a non-
hazardous location.
WARNING
Ignition coils produce a very high voltage. To reduce the risk of
electric shock when conducting RPM tests, DO NOT touch the
uninsulated ends of the test probes, the ignition coil, or the coil
terminals when the engine is running.
