Instrument indicates measured levels above the alarm / trip setpoint.
2.
Circuit. failure.
3.

3.
Downscale failure.
For the auxiliary building ventilation system, at least once every 18 months, the CHANNEL FUNCTIONAL TEST shall.also demonstrate automatic j'
isolation of this pathway.if the following condition exists:
1 Instrument indicates measured levels above the alarm / trip setpoint.
'(3) The initial CHANNEL CALIBRATION shall be performed using one or more of y
the reference standards certified by the National Bureau o! Standards or usir.g standards that have been obtained from suppliers that participate e
i in measurement assurance activities with NBS.
These standards shall permit calibrsting the 3ystem over its intended range of energy and 11 measurennent range.
For subsequent CHANNEL CALIBRATION, sources that have L
been related to the initial calibration shall be used.
