RTM Elster AMCO applicative PFS Coronis Systems
4.5.Meter reading sampling period configuration
Several RTM Elster AMCO embedded features (datalogging in time steps, leakage detection, back flow
detection) are based on periodic reading management. So, in order to synchronize these features RTM
Elster AMCO offers the possibility to program a kind of “Meter Reading Sampling Period” principle that is
shared between the features listed above in parenthesis.
4.5.1.Reading sampling period parameter
 For both RTM Elster AMCO profile (pulse or encoder)
Reading sampling period (internal parameter ID = 0x07)
Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0
[b7:b2] : Sampling period expressed in time units
minimum : once a minute
maximum : 63 times 30 minutes = 31 h 30 min
[B7..B2] cannot be set to zero !
[b1:b0] : time unit
00 : 1 minute
01 : 5 minutes
10 : 15 minutes
11 : 30 minutes
ATTENTION :
1) Meter sampling reading management starts only on associated feature activation (datalogging in
time steps, back flow or leakage detection). This allows to avoid power consumption (especially
when encoder profile is selected) while no periodic sampling is necessary. Once one of this
associated feature is activated, the sampling will start on nex hour “on the dot”.
2) Each meter reading sampling period parameter modification must be followed by a user
initialization of all the associated features (datalogging in time steps, back flow or leakage
detection).
4.5.2.Sampling activation type parameter
 For both RTM Elster AMCO profile (pulse or encoder)
Sampling activation type (internal parameter ID = 0x08)

This parameter allows to program the way the user wants the RTM Elster AMCO to start reading sampling
mechanism on associated feature activation.
➢ Immediate Start: using this activation type, user wants the RTM Elster AMCO to start the meter
reading sampling immediately after associated feature activation (datalogging in time steps, back
flow, or leakage detection).
➢ Start on next hour on the dot: using this activation type, user wants the RTM Elster AMCO to start
the meter reading sampling on next hour on the dot after associated feature activation (datalogging in
time steps, back flow, or leakage detection).
ATTENTION:
If the user wants the meter reading sampling to be synchronized on each RTM Elster AMCO which is
part of a Fixed Network System, it is advised to use “start on next hour on the dot” since RTC on each
RTM is updated automatically through radio synchronization mechanism.
