PQMII POWER QUALITY METER – INSTRUCTION MANUAL
running total of all valid Trace Memory Triggers from the last time power was applied to
the PQMII. The Total Trace Triggers counter will rollover to 0 at 65536. The trace memory
feature is implemented into the EnerVista PQMII Setup Software as shown below.
Select the Setpoint > PQMII Setup > Trace Memory Setup menu
item to setup the trace memory feature.
The Trace Memory Usage parameter is set as follows:
• 1 x 36 cycles: upon trigger, the entire buffer is filled with 36 cycles of data
• 2 x 18 cycles: 2 separate 18-cycle buffers are created and each is filled upon a
trigger
• 3 x 12 cycles: 3 separate 12 cycle buffers are created and each is filled upon a
trigger
If the Trace Memory Trigger Mode is set to "One-Shot", then the trace memory is triggered
once per buffer; if it is set to "Retrigger", then it automatically retriggers and overwrites the
previous data.
The Trace Memory Trigger Delay delays the trigger by the number of cycles specified. The
Voltage, Current, and Switch Inputs selections are the parameters and levels that are used
to trigger the trace memory. Clicking Save sends the current settings to the PQMII.
