Alerts and Diagnostics
Electronic Alerts advise when there is an electronic
error in memory
Operational Range Alerts notify when PV range and
sensor range changes might affect calibration
Rate Limit Alerts indicate rapid rise or fall in displacer,
which can signify abnormal operating conditions
RTD Alerts show health and condition of connected
RTD
Sensor Board Alerts indicate if the device is operating
above or below maximum recommended limits;
advises if the electronic sensor electronics cannot
communicate properly
Input Compensation Error Alerts advise of “Bad” or
“Uncertain” status of AO connection or setup.
Simulate Function
Simulate Active, when enabled, simulates an active
alert without making it visible.
