Calibration | 5-7
When performing a primary calibration or the first calibration after a
primary calibration, the reading and the setpoint values often won’t
match. Once the first regular calibration after a primary calibration is
performed, the readings should match.
You are then prompted to calibrate the zero gases:
O2 xx.x % Set xx.x %
Press ENTER to Zero
5. Press Enter when the zero gas reading(s) on the left of the display stabi-
lizes. The reading on the far right of the first display line shows the setpoint
value you entered for the O
2
zero gas using the Cal Gas Values menu
option. This O
2
zero gas setpoint value should match the cal gas cylinder
for the O
2
zero gas connected to your RCU.
Then, if you specified a recovery time, the system will display the recov-
ery time remaining:
Recovery xx:xx
System Calibrating
The system returns to monitoring process readings.
