Calibrating the Quick Check 600/800 Verifier
Even though the verifier is calibrated at the factory, you should calibrate it before
its first use to ensure its accuracy. For continued accuracy, periodically calibrate
the unit during normal operation. You calibrate the unit using a reflectance page
that is included in the pack of accessories. Each page has a serial number on it.
For accurate calibration and data collection, you scan the reflectance page ten
times and the Quick Check 600/800 Verifier performs a consistency test. If it
passes, the unit is calibrated.
If, during the measurement of a symbol, a scan reflectance value of
XX or — —
appears on the display or on a printout, an out-of- range reading was recorded.
Recalibrate the unit and then rescan the symbol.
The reflectance page is a precision standard made of photographic materials. If
it becomes physically damaged or dirty, replace it to insure proper calibration. To
order a new reflectance page, contact your sales representative.
♦ To calibrate the Quick Check 600/800 Verifier:
1. Using the proper scan technique, scan the reflectance symbol from the
accessory pack. You will hear a long beep followed by two short beeps after
the first good scan, and the LCD displays
REFLECTANCE CALIBRATION
-9- More Scans!
.
2. Continue to scan the reflectance page for a total of ten good scans. After
each good scan, a single beep sounds and the display indicates how many
good scans you need to obtain. After the tenth good scan, three beeps
sound and the message
Now Lift the Scanner Up off the
Target
appears. When you lift the scanner up, the opening display
appears. To scan, set the wand scanner on a symbol’s quiet zone.
