9. Reconnect the tubing to the Column Block.
10. Power up the analyzer and computer.
11. Allow the analyzer to warm up then perform a leak check on the
sample system fittings that were disconnected. See “Sample System
Leak Check” in Chapter 3.
Analyzers without Heated Cells:
If the leak check passes, continue with Step 12.
Analyzers with Heated Cells:
If the leak check passes, replace the Insulating Jacket or close the Oven
door to allow the Cell to warm up to normal operating temperature
and stabilize and then continue with Step 12.
12. Perform an Auto-Setup.
13. After the Auto-Setup is complete, change the Flow Control to ‘3’
(zero) and perform a manual Zero. Click OK then Apply. Do not save
the changes to EEPROM.
14. After the Zero is complete, change the Flow Control to ‘0’ (auto). Click
OK then Apply. Save the changes to EEPROM.
15. If the analyzer uses Measured Pressure Compensation (optional),
return the setting to Measured mode. To do this, view the Cell/Misc
Parameters dialog box and enter ‘0’ in the Default Cell Pres (pressure
compensation) field.
16. Open the valves isolating the analyzer from the sample stream and/or
remove the cap from the Vent Line outlet.
If using the Rotameter to set the sample gas flow rate, the arrow on the
three-way valve must be facing downward while setting the flow rate.
After the flow rate has been set, switch the Bypass Valve to the
“BYPASS” position by turning it 180° (arrow facing upward). This
will ensure no damage is done to the Rotameter during column
switching.
