Risbabh EM94-Z-V1-L-M, Panel Mount DC kWh Meter, Class 0.5, 50-150mV Shunt input, 60-300VDC, 2 Alarm/Pulse Outputs, RS485 & USB Comms, Single Line LCD Display,12-60V DC Aux Supply, Internal Logging
- 2 Pulse/Alarm Outputs
- 50-150mV Shunt Input, and nominal voltage 60-300VDC
- RS 485 communication up to 57,600 bit/s
- USB Port
- 8MB Internal Storage
- 4 x DC Measurement Only
The meter is intended for measuring, analysing and monitoring DC Power. The meter records TRMS value according to the principle of fast sampling of voltage and current signals. A built-in microprocessor calculates measurands (voltage, current,, energy, power.) from the measured signals.

Application Notes
1)Reading Data from Registers -> Download file
2)Maximum Memory Size -> Read below
Max Available Memory Locations in 8MB Size = 273030
Actual parameter stored in Each log (Memory locations used) = Date +time+Number of parameter selected by user
Considering your example for 2 parameters:
Number of parameter selected by user = 2 (kwh & kVA)
Actual parameter stored in Each log = 1(Date) +1(time)+ 2 (Parameters) = 4 (memory locations used per log)
Maximum log that can be stored = Max Memory Location/Actual parameter stored in Each log =273030/4= 68257
Timelog Interval setting = 15 minutes
Log in one day = (60 /Timelog Interval setting) * 24 =(60/15)*24 = 96 Logs
Max Days = Maximum log that can be stored / log in one day = 68257 / 96 = 711 days = 1 Year & 11 Months = 23 Months.
