MI 2092 Power Harmonics Analyser Section III Operation manual

UPPER and LOWER limits

These are the limits which define the pass window for Voltage Anomaly recording.

Any voltage value outside the specified limits is detected and stored as an

anomaly.

Use the LEFT and RIGHT keys to set the required limit (1% to 30% of nominal

voltage).

BUFFER MODE

The data storage in the data logging (recorder) function can be performed in two

ways: LINEAR or ROLLOVER.

In Linear mode, recording stops when the memory is filled.

In Rollover mode, recording only stops when the auto stop date/time is reached,

or when manually stopped.

Once memory is filled, the oldest data is over-written.

Neither mode will affect any memory allocated for Statistical Analysis.

Press ENTER to confirm the new settings or ESC to cancel.

Starting or Stopping of Data Logging is effected from the RECORD menu.

3.4. SIGNALS and HARMONICS sub-menus

These menus allow selection of signals, harmonics and calculated parameters for

storage while Data Logging (recording). A maximum of 64 signals can be selected; the

number of free locations is shown in the upper right corner of the display.
