oDefault Settings
The EM-PULSE installs with minimal user intervention.
If LEDs are green and you are happy with default factory settings
below, your installation is complete!
Each meter has default factory settings in ve Function Groups.
Review the default settings and their denitions below.
Function Group 1. Pulse Scale
Quickset pulse scale selection is the default factory setting.
With Quickset, pulse scale is automatically set based on the
largest installed CVT amperage rating as follows:
CVT Rated Amps Default Pulse Scale
5-50A 1 Wh/pulse
51-500A 10 Wh/pulse
501-5000A 100 Wh/pulse
5000+A 1 kWh/pulse
Check your CVT amperage rating to determine the pulse scale
for your input. For alternative pulse scale settings, see Section
7 - Function Groups.
Function Group 2. Pulse/Alarm Options
Fast Pulses (30ms), KY Mode is the default factory setting. Fast
pulses corresponds to a pulse width of 30 milliseconds. In
KY Mode pulses are the representative units and each pulse
output is independent. For alternative pulse widths, KYZ Mode,
or Alarm options see Section 7 - Function Groups.
Function Group 3. Energy Output Type
Real ‘True‘ Power (P) is the default factory setting. This is the
metric that utility companies typically use for billing.
For alternative Energy Output Types, see Section 7 - Function
Groups.
Function Group 4. Balanced Load Multiplier
The Balanced Load Multiplier is disabled in the default factory
settings. For options on balanced load multipliers see Section
7 - Function Groups.
Function Group 5. PowerPrint
PowerPrint is disabled in the default factory settings. For details
on how to utilize PowerPrint see Section 7 - Function Groups.
To Restore Factory Default Settings
Caution: Restoring factory default settings will revert device to
settings listed above. Any manual congurations previously set in
any of the Function Groups will be reset.
1. Hold setup button down until all LEDs blink red
(approximately 30 seconds) and release.
2. Momentarily press the setup button again within 5
seconds of the rst release.
3. Meter is now reset to factory default settings.
pFunction Groups
The EM-PULSE meter has ve Function Groups:
1. Pulse Scale
2. Pulse/Alarm Options
3. Energy Output Type
4. Balanced Load Multiplier
5. Powerprint Options
Each Function Group has factory default settings which can be
found in Section 6 - Default Settings.
This section will further dene each Function Group and detail
alternative settings that can be user selected in Section 8 - View

1Quickset pulse scale is selected based on the largest CVT size
installed. This is the factory default setting for the meter. See
Section 6 - Default Settings for usage of Quickset pulse scaling.
2Automeasure takes a sample of energy currently being
monitored and calculates the most appropriate pulse scale
after 10 seconds of sampling. Automeasure should be
initiated on when panel is fully loaded. This ensures that the
automatically chosen pulse scale will avoid pulse overload
warning condition during Normal Operation.
Function Group 2. Pulse/Alarm Options
Pulse/Alarm Options allow for setting dierent pulse types (KY
vs KYZ) and alarm outputs for alerts of phase loss or changes
from a saved PowerPrint (Function Group 5. PowerPrint). There

PowerPrint Alarm Mode: In addition to the LED indicators
above, the PowerPrint can also alert via an output alarm when
a PowerPrint warning condition is present. This requires the
user to select Alarm Mode in Function Group 2. Pulse/Alarm
Options. With PowerPrint On and Alarm Mode selected, the
meter will now display warning conditions on the LEDs and
provide an alarm output to your controller.
KYZ Mode: Representative pulse is an edge and 2 pulse
outputs form a complimentary pair.
Alarm Mode: Output 2 provides a normally closed alarm
output. The default alarm is for phase loss of one or more
channels in a multi-phase installation.
PowerPrint Alarm Mode: When PowerPrint is turned on Output
2 provides a normally closed alarm output for all PowerPrint
alarm conditions (See Function Group 5. PowerPrint Options
below for all alarm conditions)
Function Group 3. Energy Output Type
There are 3 Energy Output Type settings in the EM-PULSE
meter: Real ‘True’Power, Reactive Power, and Apparent Power.
Energy Output Type Energy Units
Real ‘True’Power (P) - Default Measured in watts (W or kW)
Reactive Power (Q) Measured in volt-amperes reactive
(VAR or kVAR)
Apparent Power (S) Measured in volt-amperes (VA or kVA)
Function Group 4. Balanced Load Multiplier
The Balanced Load Multiplier is utilized so that one CVT can
extrapolate power of a balanced load (e.g. motor) without
actually monitoring all 3 phases. The multiplier can be applied
to one or more CVT channels, meaning you can monitor up to
three motors with one meter:

Function Group 5. PowerPrint
PowerPrint is a power quality alarm that enables the meter to
learn and save characteristics of the system being monitored.
Based on recorded values, the meter can provide alarm
conditions and allow user to evaluate system status at a later
time. This is an optional feature, but as PowerPrint is turned
on, the meter identies each CVT connection and saves
settings on the following parameters:
1. Which channels have a CVT connected
2. Amperage rating and internal serial number of each CVT
3. System voltage
4. System frequency
5. Phase voltage angle
PowerPrint can only learn and save characteristics for
channels with a properly installed CVT. If the CVT is displaying
a warning or error condition during Normal Operation, take
