Option Range Default Description
Rapid Voltage Changes
Repetition Rate 1-10 1 Defines the maximum repetition rate in variations
per hour (equal or less than) for rapid voltage
changes. Voltage changes at higher rates are not
classified since they will be subject for flicker.
Flicker
Pst Period 1-10 min 10 min Defines the period of time for the short-term
flicker evaluation. The standard setting of 10
minutes can be temporarily changed in the device
for testing purposes.
Harmonic Voltage
THD, up to
order 25-50 40 Defines the highest harmonic order included in
the THD evaluation.
Harmonics, up
to order 25-50 25 Defines the highest harmonic order for evaluation
of the harmonic voltages.
Interharmonic Voltage
Evaluation Disabled,
Enabled Disabled Enables the evaluation of the interharmonic
voltages
THD, up to
order 25-50 40 Defines the highest interharmonic order included
in the THD evaluation.
Interharmonics,
up to order 25-50 25 Defines the highest harmonic order for evaluation
of the interharmonic voltages.
Mains Signaling Voltage
Evaluation Disabled,
Enabled Disabled Enables the evaluation of the mains signaling
voltages
1st Signaling
Frequency 110-3000
Hz 183.0 Hz Specifies the mains signaling frequency for the
compliance evaluation
2nd Signaling
Frequency 110-3000

Modbus Point Mapping
The PowerSmart+ Advanced PQM provides 120 user assignable registers in the address
range of 0 to 119. You can re-map any register available in the meter to any assignable
register so that Modbus registers that reside at different locations may be simply accessed
using a single request by re-mapping them to adjacent addresses.
