Built-In Pulse Meters
Built-in pulse meters have specific measurement properties.
Measurement Properties
This table describes the measurement properties of a built-in Schneider Electric pulse meter:
| Field | Description | Comment |
|---|---|---|
| Connected To | Displays the upstream device and the digital input number to which the device is connected. The digital input number can be modified. Only the available digital inputs of the upstream device are listed. | The device can be disconnected by selecting No device connected in the list of upstream device. From this list, it is not possible to change from 1 upstream device to another. |
| Pulse weight | The active energy counter increases by this value each time a pulse is received. The list is restricted to the values that correspond to the selected meter type. | The value cannot be modified if there is only 1 possible pulse weight, for example with the iEM2000T meter.(1) |
| Offset | Sets an offset for the active energy. The value can be positive or negative. | Enables you to start the counter with the value that can be read on the meter display. |
| Upper Range | Defines when the active energy counter rolls back to zero. | The counter sets back to zero when it reaches the entered value. |
| (1) Refer to the specific pulse meter documentation for further information. | ||
Measurement Table
The active power is calculated according to the frequency of received pulses.
