Konica Minolta CM-3700A-U Plus spectrophotometer

Mask detection function

Use the optional software (SpectraMagic NX2) to enable mask detection, install the target mask (refer to the "Installing Target Mask" steps), and then check if the indicator light matches the size of the installed mask; If the size does not match, it is necessary to check whether the target mask is installed correctly (if not installed correctly, reinstall), whether there is dirt or scratches on the installation surface of the target mask (if there is, use a dust blower to remove the dust and dirt, do not touch the white coating surface of the target mask or wipe it with a cloth. If the dirt on the non white coating surface is difficult to remove, use a soft cloth dipped in ethanol to wipe it). If the problem is still not solved, contact an authorized service organization.

Attention: Detection errors may occur when the target mask is not installed correctly or is dirty or scratched.

White calibration data

The white calibration data of the white calibration board is provided under the following measurement conditions: SAV (measurement area 1 × 3mm, illumination area 5 × 7mm)/specular reflection component: SCI; SAV (measurement area 1 × 3mm, illumination area 5 × 7mm)/specular reflection component: SCE.

Install zero calibration box

First, install the target mask (SAV) for calibration in advance, and use software to set the same specular reflection component (SCI/SCE) and ultraviolet output as during measurement (when strict precision fluorescence measurement is not required (fluorescence calibration is not performed), the ultraviolet cut-off filter does not cover the xenon lamp, and the ultraviolet output is set to 99.9).

Then pull out the sample holder in your own direction and keep it open (the sample holder will remain open after being opened about 70 degrees), insert the protruding part on the zero calibration box into the groove on the device, and fix the zero calibration box with the sample holder; After installation, it is necessary to check whether the zero calibration box is loose or warped.

Attention: Do not apply external force after installing the zero calibration box to prevent it from falling off; Avoid scratching the interior of the zero calibration box or getting fingerprints or other dirt on it; When the interior of the zero calibration box is dirty, gently wipe it with a soft, clean dry cloth. For dirt that is difficult to remove, wipe it with a cloth dipped in ethanol; When internal scratches or dirt cannot be removed, the zero calibration box needs to be replaced.

Install white calibration board

Install the target mask (SAV) for calibration in advance, and set the same specular reflection component (SCI/SCE) as during measurement through software (when strict precision fluorescence measurement is not required (fluorescence calibration is not performed), the UV cut-off filter does not cover the xenon lamp, and the UV output is set to 99.9).

Pull out the sample holder in your own direction and keep it open. Press the sample holder into the groove on the back of the white calibration plate as shown in the diagram to complete the installation.

Attention: If the set calibration start time (8 hours) has been exceeded since the last white calibration, "white calibration required" will be displayed when the device is turned on. Calibration must be performed before using the device; When using the WAA (Wavelength Analysis and Adjustment) function, it needs to be executed after white calibration, which takes about 20 seconds. After confirming the completion of WAA according to the progress bar displayed in the software, the white calibration board can be removed; The white calibration data has been set in the device at the time of purchase for white calibration; The white calibration board may discolor when exposed to light, so it should be covered when not in use to avoid exposure to external light; Avoid scratching or getting fingerprints or other dirt on the white calibration board; When the white calibration board is dirty, gently wipe it with a soft, clean dry cloth. For dirt that is difficult to remove, use a cloth dipped in ethanol to wipe it off. Then use a cloth dipped in water to wipe off the ethanol and dry it before use; When the white calibration board is scratched or the dirt cannot be removed, it needs to be replaced. After replacement, the data of the new white calibration board should be set as white calibration data.

Set up samples (reflectivity measurement)

When measuring the reflectivity of thin film or sheet samples, first install the sample into the sample holder, and then install the sample holder onto the equipment; When measuring samples that cannot be installed in the sample holder, remove the sample holder and make the sample measuring port in close contact with the sample for measurement.

Attention: The maximum thickness of the sample installed on the sample rack is 30mm.

reflectance measurement

Install the target mask for measurement in advance, and set the measurement area, specular reflection components, and ultraviolet output in advance through software.

Pull out the sample rack in its own direction and keep it open, put the sample in the sample rack, adjust the sample position so that the part to be measured is within the measuring point (when moving the sample position, pull out the sample rack in its own direction and keep it open to protect the sample surface), and then use the optional SpectraMagic NX2 color data software to perform the measurement; If the trigger measurement mode is selected, the measurement can also be performed through the measurement button on the device status panel.
