ET Tracking
Maximum ET Value
Pressure Module Electronics Temperature (ET) highest
measured value
ET Up Count
The total number of minutes that the Pressure Module
Electronics Temperature (ET) has exceeded the upper stress
limit
Minimum ET Value
Pressure Module Electronics Temperature (ET) lowest
measured value
ET Dn Count
The total number of minutes that the Pressure Module
Electronics Temperature (ET) has been below the lower
stress limit
ET Dn TimeStamp
Displays time elapsed since the Pressure Module Electronics
Temperature was last measured below the ET lower stress
limit
ET Up TimeStamp
Displays time elapsed since the Pressure Module Electronics
Temperature last measured as exceeding the ET upper
stress limit
MBT Tracking
Maximum MBT Value
Meter Body Temperature (MBT) highest measured value
MBT Up Count
The total number of minutes that the Meter Body
Temperature (MBT) has exceeded the upper stress limit
Minimum MBT Value
Pressure Module Meter BodyTemperature (MBT) lowest
measured value
MBT Dn Count
The total number of minutes that the Meter Body
Temperature (MBT) has been below the lower stress limit
MBT Up Limit
High Meter Body Temperature stress limit – if the Meter
Body Temperature exceeds this limit, the MBT Up Count and
MBT Up Timestamp will be updated. Value is equal to “Max
MBT Limit” minus 10% of limits range.
MBT Up TimeStamp
Displays time elapsed since the Meter Body Temperature
last measured as exceeding the MBT upper stress limit
MBT Dn Limit
Low Meter Body Temperature stress limit – if the Meter Body
Temperature drops below this limit, the MBT Down Count
and MBT Down Timestamp will be updated. Value is equal to
“Min MBT Limit” plus 10% of limits range.
MBT Dn TimeStamp
Displays time elapsed since the Meter Body Temperature
was last measured below the MBT lower stress limit
Supply Voltage
Maximum Supply Voltage
Value
Displays the highest recorded value of the Pressure Sensor
Supply Voltage (AVDD)
Minimum Supply Voltage
Value
Displays the lowest recorded value of the Pressure Sensor
Supply Voltage (AVDD)
Supply Voltage Dn
TimeStamp
Displays the time elapsed since the Pressure Sensor Supply
Voltage last exceeded the Max Supply Voltage Value
Supply Voltage Up
TimeStamp
Displays the time elapsed since the Pressure Sensor Supply
Voltage last dropped below the Min Supply Voltage Value
