4.1.16. Temperature Stability (Display Code 230)
The temperature stability calculation is performed. This alert will not occur
when the Warm-up is active.
4.1.17. Mounting Orientation Alert (Display Code 251)
This condition is reported when the device detects that the mounting
orientation does not agree with the orientation specified in the selected gas
page.
4.1.18. Voltage Input Out of Limits (Display Code 260)
This condition is reported when the voltage on the device power input is
outside of the following limits:
• +/- 25% of the nominal 24 Volts for 0.2 seconds
• +/- 20% of the nominal 24 Volts for 1 second.
4.1.19. Totalizer Overflow Alert (Display Code 270)
This condition is reported when the flow totalizer reaches its maximum value.
The flow totalizer is a 64-bit unsigned integer which reports total flow in
sccm. When the totalizer value reaches its maximum value of
0xFFFFFFFFFFFFFFFF (greater than 18 * 1018) sccm, the totalizer will stop
and the Totalizer Overflow Alert will occur. The flow totalizer value can be
reset to zero by writing a zero to object 0x2000:01.
4.1.20. Warm-up (Display Code 299)
This condition is reported when the device has been powered for less than
the time specified as the device warmup time, typically 60 min. During this
period, the device has not reached equilibrium temperature and may not be
accurate to specification.
