4.6.1
Pulse Output Setup
This function appears only if the pulse initiation option was ordered with the EPM 5100.
There are two pulse initiation output channels that are set up with this function. The
options available are:
Output 1
Output 2
Exit
Selecting Output 1 with the
↵
key displays the setting:
Move through the setting positions with
↵
, then set the desired value with the
V
and
U
keys. When the weight has been set, press
↵
to advance to the energy units, then choose
among kVAh, kWh, kVarh, and kQh. Confirm your choice by pressing
↵
.
This setting defines the incremental energy usage level at which pulses are transmitted
from the output. For instance, if kWh is selected with a pulse weight of 0.15, as illustrated
below, then a pulse is sent for each 150 watthours of energy consumed.

Upgrading from Electromechanical Meters
When upgrading from an electromechanical watthour meter with pulse initiation to the
EPM 5100 with pulse initiation, a mathematical conversion is required to obtain the proper
value for programming the meter. The formula is:
