ection 3: Configuration, Startup and Operation 6888Xi Advanced Electronics Instruction Manual
December 2012 PN 51-6888Xi
Failed Temperature – With the extended temperature function enabled and the operating
above the heater set point, the process temperature varied by more than ±5°C during the
calibration cycle.
Gas 1 Tolerance Error – The measured value for gas 1 varied more than ±10% from the pro-
grammed value. Possible causes are incorrect gas value programmed in the 6888XI, incor-
rect gas value in bottle, or gas bottle is empty. This error can occur only if the Tolerance
Check feature is active.
Gas 2 Tolerance Error – The measured value for gas 2 varied more than ±10% from the pro-
grammed value. Possible causes are incorrect gas value programmed in the 6888XI, incor-
rect gas value in bottle, or gas bottle is empty. This error can occur only if the Tolerance
Check feature is active.
AutoCal No Resp – No communication or loss of communication to the SPS4001B or IMPS.
AutoCal OutofSync – Loss of communication synchronization to the SPS4001B or IMPS.
AutoCal Abort – The SPS4001B or IMPS aborted the calibration cycle due to a low gas bot-
tle indication.
WarmUp Abort – Attempted to perform a calibration during warmup.
Alarm Abort – Another alarm occurred and caused the calibration cycle to abort.
In the event of a calibration failure, perform the following steps. Otherwise, proceed to the
next step.

d. From the DIAGNOSTIC menu, select ACKNOWLEDGE ALARMS then press ENTER.
e. From the ACKNOWLEDGE ALARMS menu, select ACK CAL FAILED then press ENTER.
f. When complete, press EXIT twice to return to the main display screen.
g. Press DIAG to verify the CAL FAILED alarm no longer is shown.
7. If the Calibration Acknowledge parameter is ON, perform the following steps. Otherwise,
proceed to the next step.

b. Press DIAG to view the alarms. A CAL CHANGED alarm should be shown.
c. Press EXIT to return to the DIAGNOSTIC menu.
d. From the DIAGNOSTIC menu, select ACKNOWLEDGE ALARMS then press ENTER.
e. From the ACKNOWLEDGE ALARMS menu, select ACK CALIBRATION then press ENTER.
f. In this screen, a “Ctrl Loop to Manual” warning occurs. Remove the 6888XI from any
automatic controls loops to avoid a potentially dangerous operating condition. Press
ENTER when ready to continue.
g. The next screen shows the CURRENT CAL and NEW CAL slope and constant values.
Press ENTER to continue.
h. Use the UP and DOWN arrow keys to change the value from NO to YES or YES to NO.
Press ENTER to continue. Press EXIT twice to return to the main display screen.
i. Press DIAG to verify the CAL CHANGED alarm no longer is shown.
