Ensure that the module’s Port setup register matches the meter’s output you want to control. If the port you want to use does not appear in the Port setup register’s list, that port is in use by another module. Edit the port setup register of the module using that port and set it to NOT USED – the port will then be available to other modules.

Calibration Pulsing Relay DO4

Solid-state relay DO4 is factory configured for calibration pulsing and requires no further setup. The Calibration Pulser module labeled kWh Pulser –D4controls this port. By default, the module is linked to the kW del+rec output of the Arithmetic module labeled “del, rec” (in the Demand Framework). (This Arithmetic module is linked to the MU Power Meter module’s MU kW tot output.) The port will output a pulse for every 1.8 Wh accumulated (in NORMAL or TEST mode). This is the same pulsing rate as the middle LED on the front panel of the meter.
