Current measurements
These Snap-Arounds are designed to take current measurements
on circuits with a maximum voltage difference of 1000VAC between
any conductor and ground potential. Using the Snap- Around for
current measurements on circuits above this voltage may cause
electric shock, instrument damage and/or damage to the equipment
under test. Before measuring current make certain that the test leads
are removed from the instrument.
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 / position.
2. Press the trigger to open the transformer jaws and clamp them around a
conductor. Jaws should be completely closed before taking a reading.
3. The most accurate reading will be obtained by keeping the conductor across
center of the transformer jaws.
4. The reading will be indicated on the 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 Funtion switch to the " " position.
2. Turn off power to the circuit under test. External Voltage across the
components causes invalid reading.
3. Connect the test leads to the two points at which continuity is to be
tested. The buzzer will sound if the resistance is less than approxi-
mately 30Ω.
Diode tests
1. Set the Function/Range switch to the "
2. Turn off power to the circuit under test. External voltage across the
components causes invalid readings.
3. Connect the red test lead to the "VΩ" jack and the black test lead to
the "COM" jack.
4. Touch probes to the diode. A forward-voltage drop is about 0.6V
(typical for a silicon diode).
5. Reverse probes. If the diode is good, "OL" is diaplayed. If the diode is
shorted, "0.00" or another number is displayed.
6. If the diode is open, "OL" is displayed in both directions.
7.Audible Indication: Less than 0.03V.
