f Toggle on the DC power switch on the right edge of the SmartScanNG² detector.
g Wait until 20 more trains have passed over the site and then return to step 1 .
19 On the Train Summary report, check the column marked "Average."
For each train, the values in the two columns under this heading should be within four
degrees of each other.
20 If the columns aren't within four degrees and if the scanner optics are clean, recalibrate
and realign the scanner.
21 On the Train Summary report, check the last column of the report.
The last column shows the system battery voltage when each train passed the site. It
should show values between 12.7 and 14.5 volts (12V systems) and 25.4 and 29.0
volts (24V systems). Values outside this range may be caused by:

No AC power for an extended period

Improperly adjusted float voltage

Defective battery

Blown fuses

Defective battery charger
22 If the most recent value isn't within the valid voltage range, investigate and fix any
problems before proceeding.
23 Leave the SmartScanNG² detector and the battery charger plugged in, powered, and
turned on.
24 If this is a double-track site, repeat steps 1 through 28 for the other track (that is, for the
other SmartScanNG² system).
