Status bits
The STPM10 includes 8 status bits which provide information about the current status of the
meter. The status bits are the following:
Status bit description
All these signal can be read through the SPI interface. See
details on the status bit location in the STPM10 data records.
No-load condition
Σ Δ signals status
Line frequency range
Tamper condition
Current channel selection
Trend of the line voltage
Output pin check
Data validity
Description
Doc ID 17728 Rev 3
BIL = 0: No-load condition not detected
BIL = 1: No-load condition detected
BCF = 0: Σ Δ signals active
BCF = 1: One or both Σ Δ signals are stacked
BFR = 0: Line frequency within the 45 Hz - 65 Hz range
BFR = 1: Line frequency out of range
BIT = 0: Tamper not detected
BIT = 1: Tamper detected
MUX = 0: Primary current channels selected by the tamper
module
MUX = 1: Secondary current channels selected by the tamper
module
LIN = 0: Line voltage going from the minimum to the maximum
value. (dv/dt > 0)
LIN = 1: Line voltage going from the maximum to the minimum
value. (dv/dt < 0)
PIN = 0: Output pins are consistent with the data
PIN = 1: Output pins are different with the data, this means an
output pin is forced to 1 or 0
HLT = 0: Data records reading are valid.
HLT = 1: Data records are not valid. A reset occurred and a
restart is in progress
