Function
a
Four Channel
Lab Scope
Displays four Lab Scope channels automatically.
a
Four Channel
Graphing Meter
Displays four Graphing Multimeter channels
automatically.
a
Ignition Probe
Measures secondary Ignition voltage 2 to 50kV. Displays
secondary ignition (kV) waveforms.
a
a
a
Volts DC
Measures DC (direct current) voltage. DC voltage is
measured through test leads connected to a DC circuit.
a
a
Volts DC -
Average
Measures DC voltage using a filter to determine the
average voltage over a period in time. DC voltage is
measured through the two test leads connected to a DC
circuit.
a
a
Volts AC RMS
Measures the effective AC voltage, not the peak voltage
which results in measurements with higher accuracy. The
AC RMS (root mean square) voltage value can be
defined as the equivalent DC voltage of the AC voltage
measured. RMS values are commonly used in AC
electrical measurement, as they are more representative
of DC measurements.
