PowerWave Operator’s Manual 4-3
♦ Linearity of the Optical Density readings are confirmed by
default if the wavelength readings are accurate.
♦ Alignment of the plate carrier and standard microplate s
are confirmed by the four corner positional accuracy check.
♦ Channel-to-channel variation can be tested by completing
the turnaround test. This tests the readers ability to read
samples accurately in different plate positions.
♦ Wavelength setting accuracy. To check the accuracy of
wavelength settings, use the special Calibrator Test Plate,
Part Number 7260522. The Calibration Test Plate provides a
multiband calibration filter in location C6. The filter is
Didymium glass V10. The filter should be scanned between
580 and 590 nm in 1 nm increments using KC4. For
PowerWave 340, or if KC4 is not available, select six
wavelengths at 1 nm increments near the expected peak.
The wavelength of the maximum absorbance should be
compared with the wavelength written on the sheet
supplied with the calibration plate.
