Position for calibration pulser modules not getting reset on ION meter

While running some tests on a custom ION7550 framework I observed that the "position" of the calibrated pulser module is not getting reset despite having done a master reset on the device.

I would assume the master reset clears out everything (logs, energy, demand, min, max, ect.). But it appears the position on these modules is always remembered.

I am outputting a kWh pulse on R1 (1 kWh= 1pulse -> Kt=1000. I do a master reset, energy registers reset. However when  say 0.45kWh accumulates, the module pulses the port.

Is this normal intended behavior?

Matthew,

Did you do resetting  when there was load ? If so one second after reset was done you will have energy accumulated for sure.
