3.12 HMR3000 Warning and Alarm Settings

Tilt and magnetometer limits can be programmed in to the EERROM to generate Warning and Alarm conditions in the
status fields of the HPR sentence output.
Tilt Settings
When the tilt measured is below the warning level, the status fields will indicate 'N'.
$PTNTHPR,59.6,N,-0.2,N,-3.0,N*0F
Tilt high warning and high alarm can be user programmed. When the pitch or roll measured is between the warning and
alarm levels, the HPR message will indicate this with letter. 'O' in the corresponding pitch or roll status field.
$PTNTHPR,72.9,N,-1.6,N,-29.6,O*33
When the pitch or roll measured is beyond the alarm level, the HPR message will indicate this with letter 'P' in the
corresponding pitch or roll status field, and the heading field will be null.
$PTNTHPR,,N,-1.5,N,,P*03
Four levels can be set for the magnetometer alarm and warning levels. High Warn and Alarm levels, and Low Alarm and
Warning levels. Five settings are generated depending on the measured total magnetic field value (Mag T) and the levels
programmed in the EEPROM.
Level
Low Warn < Mag T < High Warn
High Warn < Mag T < High Alarm
High Alarm < Mag T
Low Alarm < Mag T < Low Warn
Mag T < Low Alarm
