11. Click Close to exit the 32 Bit loader.
12. Go to Entry mode in PCCU.
The device has successfully been reset if you see the Startup Wizard when you reconnect with PCCU.

10.11 Lithium battery status

Prior to some maintenance procedures, especially when a Cold Start is not desirable or feasible, verify
that the Lithium battery status is OK.
To check battery status:
1.
While in the PCCU Analyzer Operation screen, select the Station Setup tab.
2.
Select the value beside lithium battery status.
3.
If Lithium Battery Status value reads OK, then power may be removed from the device without
causing a cold start.
4.
If Lithium Battery Status reads Low Voltage or Not Connected, then the lithium battery should
be connected or replaced prior to removing power from the device. See section
Replacing the lithium battery.

10.12 Change the clock

When measurement streams are instantiated on the analyzer, changing the clock could affect the time
when log period entries are made. To protect the integrity of accounting audit trails, the analyzer
handles these types of clock changes as follows (examples are based on a 60 minute Log Period).

10.12.1 Clock change not crossing a log period boundary

When the next log period entry is made, the clock is not altered.
Example: If the present time is 4:15 p.m. and the clock is changed to 4:05 p.m. of the same day, the
daily flow record is the same. The entry reflects the accumulation over a 70 minute time period (15
minutes plus 55 minutes).

10.12.2 Forward clock change crossing a log period boundary

This forces a log period entry for part of the log period that has accumulated since the last log period
entry. The analyzer then advances to a new data flow record and begins maintaining the balance of
the day's data in a newly defined boundary.
Example: If the present time is 4:55 p.m. and the clock is changed to 5:05 p.m. of the same day, the
entry reflects only a 55 minute average accumulation. Then a new flow record is written and this
period is also based on a 55 minute accumulation.
