MiniScan EZ Standardization
The MiniScan EZ must be standardized on a regular basis to keep it operating properly. The
standardization interval is user selectable up to 8 hours. A prompt to standardize is provided if the
interval is exceeded.
Since the MiniScan EZ is battery operated, the unit will continue to take measurements until the
battery needs to be charged. Navigation will be enabled during this low battery period and allow the
download of measurements stored in the MiniScan EZ.
Standardization on a MiniScan EZ model with 45°/0° geometry requires reading of the black glass and
white tile that are contained in the calibration cylinder. Standardization on a diffuse/8° MiniScan EZ
requires you to read both the light trap and the white tile in the calibration cylinder.
Standardization can be done through EasyMatch QC (by selecting Sensor Menu > Standardize or by
clicking the Standardize button on the default toolbar) or directly through the MiniScan EZ firmware.
Bottom of Scale. Place the black glass (MiniScan EZ model with 45°/0) or light trap (diffuse/8°
MiniScan EZ) under the instrument port to read Bottom-of-Scale.
