16.6 NEG Pump Troubleshooting

If an MS Pressure Warning message is displayed on the front panel of the
HAPSITE, go to the TUNE STATUS option on the PROBES & SM page menu. See

Figure 16-11

. If the MS warning is seen on the Laptop, (see

Figure 16-11

) check

the System Status bar on the right side of the System Setup screen or go to the
Service Module Tab in the Properties menu on the Laptop in Plus IQ to check the
MS Pressure. See

Figure 16-12

and

Figure 15-7 on page 15-8

Figure 16-12 Pressure Location on HAPSITE

A MS Vacuum Pressure reading of Below Gauge Range indicates the HAPSITE
is ready to sample. If the MS Vacuum Pressure is 3E-003, order a new NEG Pump.
If the MS Vacuum Pressure is 6E-003, replace the NEG Pump.

NEG Pumps have an expected life of approximately 150 hours. If the NEG Pump
has 70 hours or less consider trying a bakeout (formerly called Reactivation) to
extend the NEG Pump’s life. To check the NEG Pump hours used, go to the NEG
Status
tab on the Properties menu. See

section Figure 16-13

.

NOTE: If the NEG Pump has more than 150 hours, a bakeout or reactivation can

be tried, though the results are likely to be limited.
