Electro-Voice 1252, 250 Time, Status, Frequency, Flicker Monitoring, Instantaneous Readings

Time

Start/Reset is the time when Flicker was started or reset. A Reset of Flicker causes the Max/Min values to be cleared and restarts the Flicker Pst and Plt timers. A Start of Flicker is also equivalent to a Reset in that the PST and PLT are restarted and the Max/Min Values are cleared.

Stop corresponds to the time when Flicker is turned off. Current is the current clock time.

Next Pst is the countdown time to when the next Pst value is available. Next Plt is the countdown time to when the next Plt value is available.

Status

Indicates the current status. Active = On. Stopped = Off.

Frequency

Base is the current operating frequency selected by the user (50 or 60 Hz). Current is the real time frequency measurement of the applied voltage.

Base Voltage is the normalized voltage for the selected frequency (230 V for 50 Hz or 120 V for 60 Hz).
