Calibration; X84; „ Zero Calibration; Zero Calibration - Konica Minolta CM-M6 Instruction Manual

Calibration

The following two types of calibration can be performed with this instrument.
• White calibration : The reflectance is measured in advance using a known white calibration plate in order to
provide a reflectance scale.
• Zero calibration : Only the amount of stray light is measured with the zero calibration box in advance in order
to eliminate the effects of the stray light.

Zero Calibration

„ „
Since this instrument stores the data of the previous zero calibration, repeating zero calibration every time the
instrument is turned ON is not necessary. If, however, the temperature or other measurement conditions change
greatly, or if the instrument is not used for a long period of time, zero calibration must be performed before white

calibration.

• The effects of stray light (i.e., light generated due to the flare characteristics of the optical system) will be
Memo
compensated for automatically by the zero calibration data.
• The amount of stray light may change because of dust or dirt that has collected in the optical system, humidity,
repeated operation, or vibration and shock exerted on the instrument. In this case, performing zero calibration
periodically is recommended.
• If the instrument is not used for long periods of time, the zero calibration data stored in the instrument may
Notes
be lost. If the data is lost, zero calibration must be performed again.
Operating Procedure Start the procedure from the measurement screen.

Press [MENU], and then use [] or [] to display the
<Calibration> screen.
The following screen prompting calibration is displayed
Memo
when the instrument is turned ON. To perform zero
calibration, select "Calibration (Including Zero Cal.)". After
completing zero calibration, perform white calibration.

Use [] or [] to move the cursor to "Calibration
(Including Zero Cal.)", and then press the
[Confirmation] key.
