Measuring Voltage - IDEAL 61-557 Instructions

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 61-557 will defeat the influence of Ghost or Stray
voltage.
LoZ is typically selected only when a voltage is indicated when you are expecting
zero voltage because you have turned off a breaker. Various factors influence the
reading and selecting LoZ rather than VAC on a live line may produce an inaccurate
AC voltage value.
The probe holders on the back may be used to correctly
space the two probes to access a standard outlet for
Voltage measurements between the hot and neutral.
Remove the protective caps to expose the probe tips
and be sure to reinstall them when finished.
