Frequently Asked Questions (FAQs)
The message ‘Not configured’ is shown on the Prometer 100 display.
The message ‘Not configured’ is displayed when the parameters are not configured in the meter.
For e.g, Bar Graph of Energy parameter for the logger will be available on meter display if user configures
logger energy in meter. Similarly Rate Registers and Demand Registers will be available if user configures TOU
energy in meter.
Is it possible to have different IDs for the two RS485 communication modules attached to the meter?
For DLMS, different IDs can be used for both the RS485 communication modules. While for Modbus, same IDs
will be used for both the RS485 communication modules.
Are the harmonics data up to 31
st
order available on meter display?
The voltage and current harmonics data up to 31
st
order is not available on meter display and can be accessed
using M-Cubed 100 and via the communication protocol.
Which information is not available on the Prometer 100’s display for 3-phase 3-wire?
On configuring Phase 2 displays for 3-phase 3-wire, the Phase 2 parameters such as energy, voltage, current,
Power, P.F, harmonics, L1-L2 voltage phase angle, L2-L3 voltage phase angle and current symmetry data will
be displayed as “……..”.
Which events are not applicable for 3-phase 3-wire?
Phase 2 current reversal, Phase 2 current miss, CT open, CT bypass, neutral disturbance and invalid phase
association are not applicable for 3-phase 3-wire.
Will the existing meter data reset on changing configuration?
The existing meter data will be reset on configuring/changing existing energy channels, logger parameters or
scaling information in meter.
What happens if a new successive adjustment is made when one is already underway?
The current adjustment will be stopped and the new begun.
When summer time starts, the clock jumps one hour. What happens if the user sets the meter to a DST
time within that hour?
The meter will ignore the new time because that hour “does not exist”.
Is logger’s data affected by daylight saving time change? What data is affected by daylight saving time
change?
No, the logger’s data will not be affected by the daylight saving time change as the loggers, events and daily
energy snapshot are logged as per base time. The daylight saving time is applicable only for TOU rate registers,
TOU demand data and billing data.
