Notes:
1) The Standard Data Recorder can be triggered by Setpoint ( Triggered by Setpoint ) or on a time basis using the meter clock ( Triggered
by Timer ).
For Triggered by Setpoint , when the Setpoint goes active, the Data Recorder starts to record, and when the Setpoint becomes
inactive, the Data Recorder stops.
2) If the Recording Depth is set to 0 , the Data Recorder will be disabled.
3) Recording Offset can be used to delay the recording by a fixed time from the Recording Interval . For example, if Recording Interval is
set to 3600 (hourly) and Recording Offset is set to 300 (5 minutes), the recording will take place at 5 minutes after the hour every hour,
i.e. 00:05, 01:05, 02:05…etc. The programmed value of Recording Offset should be less than that of Recording Interval .
4) Appendix A provides a list of available parameters for data recording. All parameters are available for standard data recording. If
Number of parameters is set to 0 , the Data Recorder is disabled.
5) Modifying Recording Mode , Recording Depth , Recording Interval , Recording Offset , Number of Parameters and Parameters 1 to 16
will clear the DRx Log and reset the DRx Pointer to “0”.

Notes:
1) If Recording Depth is set to 0 , the Energy Log is disabled.
2) When the current time meets or exceeds the Start Time , the Interval Energy Recorder starts to record.
3) Modifying Recording Depth , Recording Interval , Start Time , Number of Parameters and Parameters 1 to 5 will clear the Energy Log
and reset the Energy Log Pointer to “0”.
5.10.6 Waveform Recorder (WFR) Setup
The iMeter 6 provides 2 Waveform Recorders, each with a fixed Recording Depth of 128. Each WFR can
simultaneously capture 3-phase Voltage and Current signals at a maximum resolution of 256 samples per cycles.

Notes:
1) The valid WFR formats (# of samples/cycle x # of cycles) include 0~4, which are 16x320, 32x160, 64x80, 128x40 and 256x20,
respectively.
2) Modifying the Setup Parameters of WFRx will clear the WFRx Log and reset WFRx Pointer will be reset to “0”.
