Below is our Glossary of Omnimeter Data Terms (in the order displayed in the EKM Dash software):
The following are data values that all Omnimeter models share.
Device # -- This is the number of the meter. All of our meters come with a unique 12 digit number. It is printed on the face of the meter under the LCD screen
Meter Name -- This is the name you have assigned to the meter.
Time -- This is the meter timestamp. The meter time is set in an internal clock in the meter.
Computer Date -- This is the timestamp from your computer.
Total kWh -- This is the Total kWh. The Total kWh is the measurement of energy since the meter was installed. It is Forward kWh + Reverse kWh. This is a cumulative value.
Forward Kilowatt Hour -- This is the kWh that has gone through the meter in the Forward Direction (towards the load). In a traditional install this would be measured energy going away from the Utility. This is a calculated value: Forward kWh = Total kWh - Reverse kWh
Reverse Kilowatt Hour -- This is the kWh that has gone through the meter in the Reverse Direction (away from the load). In a traditional install this would be energy going toward the Utility in the case of renewable generation.
Net Kilowatt Hour -- This is the Net kWh that has gone through the meter. Useful for knowing if you have generated or consumed more power in the case of systems with renewable generation. This is a calculated value: Net kWh = Total kWh - (2 x Reverse kWh)

Cos 1 (Power Factor1) -- Power Factor on Line 1. Power Factor is a power quality measurement. A perfect power factor is 1.00. Power factor is less than 1.00 when the voltage sine wave lags or leads the current sine wave.
Cos 2 (Power Factor2) -- Power Factor on Line 2. Power Factor is a power quality measurement. A perfect power factor is 1.00. Power factor is less than 1.00 when the voltage sine wave lags or leads the current sine wave.

Max-Dmd --- This is the Maximum Watts (average of the spike within the Max Demand Period) the meter has seen since the Max Demand was reset.
Max-Dmd Period --- This is the period of time use to calculate the Max Demand. This can be a 15, 30 or 60 minute time period.
CT Ratio -- This is a setting inside the meter. It should be set to match the amperage rating of the CTs that are connected to the meter. For example, if you are using 800 amp CTs, the meter should be set to the 800 amp CT ratio.
Status Byte -- This is used to track the status of the meter firmware.
The following data values are only available for v.4 and v.5 Omnimeter models.
Reactive Energy -- This is the reactive version of kWh. When your power factor is less than 1.00 you will accumulate kVARh. This is a cumulative value.

Reactive Power L3 -- If Power Factor on Line 3 is less than 1.00 you will see real time VARs, it is a measure of power quality with a quantity in real time.
