Analysis cannot be continued until the error is resolved.
Probable Cause 1) Incorrect adjustment of 2.0 kg/cm

pressure.
2) Inadequate pressure output from the Pneumatic Unit
3) A pressure connection tube has become disconnected.
Corrective Action 1) Adjust Main Unit 2.0 kg/cm

pressure
(See
Chapter 9, Section 4: Main Unit Adjustment
.)
2) Check the Pneumatic Unit power switch and power cord connection.
3) Check the pressure tubing connection.
4) Check the pressure output by pinching the tubing between the Main Unit
and the Pneumatic Unit. If the Pneumatic Unit pressure returns to normal,
problem is in Main Unit.
5) If Pneumatic Unit pressure is still low, adjust Pneumatic Unit pressure via
relief value.
(See
Chapter 9, Section 3: Pneumatic Unit Adjustment
.)
250 mmHg Error
Phenomena 250 mmHg vacuum dose not reach the required range.
An analysis error may occur, and the "Check Stored Data" message also
appears. Analysis cannot be continued until the error is resolved.
Probable Cause 1) Incorrect adjustment of 250 mmHg vacuum
2) There is fluid in the Pneumatic Unit trap chamber.
3) Vacuum line is blocked.
4) Inadequate vacuum output from the Pneumatic Unit
Corrective Action 1) Adjust the 250 mmHg vacuum.
(See
Chapter 9, Section 3: Pneumatic Unit Adjustment
.)
2) Check the Pneumatic Unit trap chamber for liquid. If present, discard the
liquid and reassemble. Be sure the trap chamber is securely attached.
(See
Chapter 5, Section 3.2: Remove Fluid from Pneumatic Unit Trap
Chamber
.)
3) Check the vacuum tubing connection.
4) Check the vacuum output by pinching the tubing between the Main Unit
and the Pneumatic Unit. If the Pneumatic Unit vacuum returns to normal,
problem is in Main Unit.
5) Clean the vacuum orifice.
(See
Chapter 5, Section 5.1: Clean Orifice
