Select Mode
Choose this option to set the into one of its operating modes. Each
mode is indicated on the front panel measurement display once set.
The modes are:
Normal
– Ideal for most general measurements.
Ballast
– For measuring the output of electronic ballasts. See
for application notes on this subject. The frequency displayed is the ballast
switching frequency.
Inrush
– For measuring the peak current during any event. Typically this is used
to measure the peak current when a product is switched on.
Standby
Power
–
A special mode in the analyzer that allows the user to set a
time window over which to accumulate power measurements. When set, power
measurements will update after each time window period, other available
measurements will update at the normal display update rate of 0.5 seconds. The
currently displayed power measurement represents the amount of power
accumulated over the last time window only.
Integrator
– For energy consumption (W-h) measurements over time. Ideal for
rating products whose energy consumption is not constant like washing machines
and refrigerators.
IEC Current Harmonics
– This mode is control via PC software. It enables pre-
compliant current harmonic measurements to IEC 61000-3-2 to be made. This
mode is optional on the . Please visit www.voltech.com for more
information.
IEC Voltage Flicker
– This mode is control via PC software. It enables pre-
compliant Pst measurements to be made as described in IEC 61000-3-3. Please
