• Select a Pst time range from 1 to 10 minutes. The standard measurement period is nominally 10
minutes.
• Select a Plt time range from 1 to 240 minutes. The standard measurement is nominally 12 Pst
periods (120 minutes). Plt time must always be equal to or great than and a multiple of Pst time.
This is reflected in the selections available to the user.
• Select the frequency of operation. 50 Hz is the approved frequency according to Flicker
standards. A 60 Hz implementation is available and can be selected. This implementation is the
proposed 60 Hz standard that is still in the approval process.
Remember the voltage is normalized. For 50 Hz, the normalized voltage is 230 V and for 60 Hz,
the normalized voltage is 120 V.
