White Calibration (100% Calibration) - Konica Minolta cm-5 Instruction Manual

White Calibration (100% Calibration)

White calibration (100% Calibration) must be performed prior to start of measurement after the power is turned
ON for the first time after purchase at the current settings.
• The built-in White Calibration Plate of the instrument is provided with its own calibration data.
Memo
• When automatic white calibration (100% Calibration) is set to ON, white calibration (100% Calibration) will
start automatically when the instrument is turned on.
(Except for liquid measurement or user calibration)
• The reading may fluctuate slightly due to changes in the ambient temperature or due to heat generation caused by
repeated operation of the instrument. In this case, make sure to perform white calibration (100% Calibration)
regularly.
• White calibration (100% Calibration) must be performed at the same temperature as the one at which
Notes
measurement will be performed.
• Before starting white calibration (100% Calibration), make sure that the instrument is sufficiently acclimatized
to the ambient temperature.
[Procedure]
Although white calibration (100% Calibration) is included in the Easy Setup Wizard, the following explains the
procedure to perform white calibration (100% Calibration) from the measurement screen.
1. Press the [CAL] button.
The <Measurement Condition Settings> screen is
displayed.
Confirm that the displayed measurement type,
Notes
measurement area and specular component setting match
with conditions of the measurement to be conducted.
The bottom of the <Measurement Condition Settings>
Memo
screen shows two items: Zero Calibration (0% Calibration)
and White Calibration (100% Calibration). The date of the
last calibration is displayed for each item. If no calibration
has been performed yet, "--" is displayed.
2. Use the or button and
cross key to move the cursor to
(100% calibration).
3. Go to the appropriate step according to the measurement type.
<Reflectance measurement>Refer to Step 3 (Page 56).
<Reflectance measurement using Petri Dish>Refer to Steps 3 to 5 (Page 56).
<Transmittance measurement>Refer to Steps 3 to 4 (Page 57).
<Liquid transmittance measurement>Refer to Steps 3 to 4 (Page 57).
Start the procedure from the measurement screen.
