assigning it to the digital input, the meter is able to detect and record the incoming
pulses. An energy management system can then use the information from the meter to
perform WAGES analysis.

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
Configuring standard input metering using ION Setup
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.
1. Start ION Setup.
2. Open the Setup Assistant for your meter.
