Calibration | 5-7
Remote Calibrate
1. Enter the calibration gas value to match the zero calibration gas cylin-
der you intend to use to calibrate your system (Cal Gas Values). This
value is referred to in this section as the set point value.
2. Select Initiate Cal from the Calibrate key menu.
3. Select Remote Calibration.
The following then appears on your display:
O2 xx.x Set xx.x
Press ENTER to Span
4. Press the Enter key once the O
2
gas reading on the left of the display
stabilizes. The reading on the far right of the first display line shows
the set point value you entered using the Cal Gas Values menu op-
tion. This set point value should match the cal gas cylinder value.
If your O
2
reading on the far left of the display had stabilized yet is not
near the setpoint value on the far right of the display, you should check
the cal gas value you entered to ensure that this value matches the cal gas
cylinder for that gas in the RCU.
When performing a primary calibration or the first calibration after a
primary calibration, the reading and set-point 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 gas:
O2 xx.x Set xx.x
Press ENTER to Zero
5. Press the Enter key once the zero gas reading on the left of the display
stabilizes. The reading on the far right of the first display line shows
the set point value you entered for the O
2
zero gas using the Cal Gas
Values menu option. This O
2
zero gas set point value should match
the cal gas cylinder for the O
2
zero gas connected to your RCU.
