cause subtle deviations in the indicated values. In such cases, perform white
calibration regularly.
Notes • Perform white calibration using the included White Calibration cap.
• Perform white calibration under the same temperature conditions as
when performing measurement.
• Perform white calibration after the instrument has had time to adapt to
the ambient temperature.
