Input metering
Your meter’s digital inputs can be used to count pulses from transducers and
convert the pulses to energy measurements.
Your meter’s input metering channels count pulses received from the digital inputs
assigned to that channel. The incoming pulses are used in calculating and
measuring consumption data (e.g., BTU, kWh, L, kg). Each channel must have the
following values configured to match the pulse data:
•
Pulse Weight: the pulses per unit value.
•
Unit Code: the unit of measure associated with the monitored value.
•
Demand Code: for time-based values (such as kWh), this provides the
associated demand units (kW) for demand calculations; for other values
(such as kg), this can be configured to provide rate information (kg/h or kg/s).
•
Mode: whether a pulse is based on a complete pulse or a transition.
For example, if each complete pulse represents 125 Wh, you can configure for Wh
pulsing as follows:
•
Pulse Weight = pulses/Wh = 1/125 = 0.008
•
Unit Code = Wh
•
Demand Code = kW (this is automatically set)
•
Mode = pulse
If you want to configure for kWh pulsing, you must adjust the pulse weight
calculation and unit code as follows:
•
Pulse Weight = pulses/kWh = 1/0.125 = 8
•
Unit Code = kWh

You can configure input metering with standard units and rates using ION Setup
When configuring your meter, the configuration interface may show all of the
possible ports, regardless of what is physically available on your meter.
NOTE:
Your device’s digital input must be connected to the input metering
pulse source. Review the digital inputs assigned to applications to help you
understand your existing configuration.
NOTE:
To disable an input metering channel and remove any port
associations, set Assigned Input to No connection.
1. Start ION Setup.
2. Open the Setup Assistant for your meter.
