OPTICAL SENSOR Specifications

Accuracy: 23°±5°C (73°±9°F), less than 80% rh, One year accuracy guarantee

■

Wavelength setting

resolution up to 1 nm

Up to 10 wavelength memory presets can be

configured, including the defaults for each

optical sensor. The default wavelengths for each

optional sensor are already stored in memory.

Add up to 6 more custom wavelengths and

call them up simply by pressing the λ key.

■

MAX/MIN/AVE measurement

Display maximum, minimum, and averages,

as well as make relative measurements.

■

Scaling

Adjust for sensitivity at the wavelength

level, and easily integrate the 3664 into an

inspection standard device.

Please refer to the external diagrams depicted on the next page for the exact dimensions of the optical sensors.

■

2 Power settings

Compatible to both DC power and AC

power. Choose a power method to suit

your application.

■

Relative measurement

Display measurements as relative

values, i.e., the difference from a

set reference value. Load reference

values from a measured value or define

according to your requirements.

■

Upload data through the

USB interface

Program your PC to download captured

data, configure and even control the

3664

through the USB interface.
