3.2 Technical Specifications
3.2.1 True RMS Characteristics
• For non-sinusoidal signal measurement, the Meter
provides more accurate measurement than the
traditional averaging method.
• lf in AC current mode, the Meter may display a random
reading between 1 and 50 when the input is not active.
This will not affect the accuracy of measurement.
• True RMS requires a mínimum input level, AC current
or voltage should be 2%-100% of the maximum level.
3.2.2 Dual lmpedance Characteristics
• Normal impedance(1 OM) with normal testing capabilities.
• Low impedance Lo-Z (400k0) for testing where "ghost
voltage" may be present.Ghost voltage can occur when
power supply conductors and adjacent unused
conductors create a capacitive coupling between
conductors.lf this possibility exists, or when testing for
the presence of voltage, use the Lo-Z mode to switch to
the low impedance setting to remove the ghost voltages
during measurement.
