Set Cal Timers - Cal Gas Duration
Define how long the RCU should apply the span and zero calibration
gases to the sensor during an automatic calibration or verification. You can
also set a calibration gas duration time to 0 if you don’t want to include it
in your automatic calibration sequence.
To find out how long it takes for your calibration gases to reach the sen-
sor and stabilize, select the
Inject Cal Gas menu option and time the gas
stabilization period. Then use this time frame as your calibration gas dura-
tion (we suggest that you also add a buffer to this time frame to be certain
that the gas has stabilized).
1. From the Set Cal Timers menu option, select Cal Gas Duration .
You will be prompted to enter the new span gas duration time:
O2 Span Time = xx:yy
Enter new time: Mn:Sc
2. Enter the new span gas duration time, then press Enter . Mn equals
minutes and Sc = seconds. As you type the new span gas duration
time, it overwrites the Mn:Sc text. If you want to use the currently
displayed time, press
Enter without entering a new value.
At this point, you will be prompted to enter the zero gas duration time:
O2 Zero Time = xx:yy
Enter new time: Mn:Sc
3. Enter the new zero gas duration time, then press Enter . Mn equals
minutes and Sc = seconds. As you type the new zero gas duration
time, it overwrites the Mn:Sc text. If you want to use the currently
displayed time, press
Enter without entering a new value.
