damage to the equipment under test. Before measuring cur-
rent make certain that the test leads are removed from the in-
strument.
The Snap-Around is overload protected up to 500V AC for up
to 1 min. Do not take current readings on circuits where the
maximum current potential is not known. Do not exceed the
maximum current that this instrument is designed to measure.
1. Set the Function/Range switch to the A~/A
2. Press the trigger to open the transformer jaws and clamp them
around a conductor. Jaws should be completely closed before tak-
ing a reading.
3. The most accurate reading will be obtained by keeping the con-
ductor across center of the transformer jaws.
4. The reading will be indicated on the main display.
5. Reduce the range setting if set too high until a satisfactory best
resolution reading is obtained.

Resistance measurements

1. Set the Function/Range switch to the "Ω" position.
2. Turn off power to the circuit under test. External Voltage across
the components causes invalid reading
3. Connect the red test lead to the "VΩ" jack and the black test lead
to the „COM" jack.
4. Connect the test leads to the points of measurements and read
the value from the display.

Continuity measurements

1. Set the Function/Range switch to the
Ω/
/ , to select the continuity test.
2. Turn off power to the circuit under test. External Voltage across
the components causes invalid reading.
3. Connect the red test lead to the "VΩ" jack and the black test lead
to the „COM" jack.
