Name Description
12011 CT1 Value CT1 Value
12012 CT2 Value CT2 Value
12013 CT3 Value CT3 Value
12030 Pulse Scalar Changes the scaling of the output pulses.
12040 Demand Win Demand window size in minutes; default is 15 minutes.
12050 Volts Mult Multiply volts values by this scalar. For use with stepdown transformer.
Affects all parameters that use volts.
12060 Amps Mul Multiply amps value by this scalar. For use with x:5A CTs and single leg
monitoring of a three-phase load. Affects all parameters that use amps (such
as kW).
12070 Com Settings Baud: 900 = 9600, 1900 = 19200, 3800 = 38400, 5700 = 57600, 7600 =
76800, 11500 = 115200
Parity: Add 00 = NO, Add 10 = ODD, Add 20 = EVEN
Stop bit: Add 0 = 1 (UART does not permit 0 stop bits),
Add 1 = 1, Add 2 = 2
For example: 901 = 9600 baud, no parity, 1 stop bit.
12080 Service Type A value of 1 configures the meter for Delta.
A value of 0 configures the meter for Wye.
12090 Freq Set Line frequency setting for metering. 50 = 50 Hz, 60 = 60 Hz.
12130 CTA Type CT Type for all channels. 1 = MilliVolt, 2 = Rogowski.
12131 CT1 Type 1 = MilliVolt, 2 = Rogowski.
12132 CT2 Type 1 = MilliVolt, 2 = Rogowski.
12133 CT3 Type 1 = MilliVolt, 2 = Rogowski.

10020 Data Acquisition Tick Internal sample count (gets cleared every minute): may be used to
determine if sample read is a newer sample than last read.
10140 Clear Accumulated
Measurements
Writing 1234 to the present value will reset all the accumulator
objects (kWh, kVAh, kVARh).
10190 Communications
protocol
Used to change between BACnet and Modbus communications
protocols.
12001 CT1 Phase Shift CT1 phase shift (degrees)
12002 CT2 Phase Shift CT2 phase shift (degrees)
12003 CT3 Phase Shift CT3 phase shift (degrees)
