Meter Operation

Non-Contact Voltage Sensing

First, rotate the function key to the NCV position. Place the jaw tip marked with NCV close to an AC outlet (or any AC conductor such as light switches or power cords) and scan back and forth across the outlet. Red indicator LED flashes at a frequency of 3Hz, and the buzzer beeps at a frequency of 3Hz simultaneously if live voltage is greater than 40VAC (50~60Hz) is detected. To differentiate between hot and neutral in an outlet, place the NCV tab directly next to each slot in the outlet. The tone (buzzer) will sound over the slot that is energized and not on the neutral slot. Either test lead can also be used to differentiate between the hot and neutral. Plug the red or black test lead into the V input jack on the meter. With the function switch in the NCV position, insert the probe end of just one probe into the slots on the outlet. The meter will beep and the Red LED will flash when a hot conductor is contacted.

NOTES:

While the NCV is a helpful function, it is ALWAYS RECOMMENDED that the operator verify that any electrical conductor is completely deenergized and that no voltage is present by measuring for voltage AND CONFIRMING THAT NO VOLTAGE IS PRESENT and that all applicable PPE and lock out tag out procedures be followed before attempting any work on ANY electrical distribution system.

Voltages with frequencies higher than 60Hz or electrostatic charges may also be detected by the NCV sensing antenna.

Measuring AC ( ) or DC ( ) Current (Amps)

Note:

• When measuring current, align conductor with dash marks on clamp jaws.

• For DC current point the arrow (located at base of jaws) towards the load.

Measuring AC ( ) or DC ( ) Voltage

AC V LoZ Setting*

*Note: When measuring AC voltage, Ghost or stray voltages (caused by induced voltages coupling from one parallel conductor to the next as found when measuring one conductor in multiple conductor circuits) may cause an incorrect value. Selecting the Low impedance position (LoZ) on the dial, (see inset above) while measuring voltage with the 61-757 will defeat the influence of Ghost or Stray voltage.

Verifying Continuity ( ) Measuring AC ( ) or DC ( ) Current (Amps)

• Verify the circuit is de-energized.

• The meter will sense the level of resistance and a beep if the resistance is less than 10 Ω to confirm that continuity is present.
