versatile hand-held optometer
Hand-held Meter
The X1 optometer is one of the most versatile hand-held light measurement instruments available. It combines a powerful electronic design packaged in a light-weight ergonomic housing. Its compact size makes it ideal for field service applications. A unique feature of the X1 is its capability to operate detector heads housing up to four photodiodes with all four signals displayed on the four line display with on/off backlighting. When more than one detector head is used simple and faultless selection of the calibration data is accomplished using the X1’s menu mode.
Simple to Use
Operating the X1 is simple. The meter set-up is supported by an easy to use menu. The menu allows selection of the operating mode, the detector and measurement parameter. Once set-up all settings are stored and recalled on next power-up unless reinitialized. Measurement values are displayed in absolute quantities for the particular detector connected. The X1-1 is compatible with detectors that have -4 connectors. Calibration factors are stored in the X1-1.
The latest version X1-5 offers compatibility with detectors that have -5 connectors. These connectors include calibration data in Eeprom storage within the connector and hence correct data is always read directly from detector. Detector heads with -5 connectors can be readily interchanged when used with the X1-5 optometer.
Battery or USB powered
For on-site applications the X1 is operated with two standard 1.5 V AA batteries. In remote control operation the X1 is powered through the USB interface.
Four-channel Meter
The unique feature of the X1 is the capability to operate multi-cell detector heads with up to four photodiodes with all four signals displayed or read-out via the USB interface.
Multipurpose Light Measurement Instrument
The X1 can be combined with most of the Gigahertz-Optik single cell or multi cell light detector heads for use in a wide application range of radiometric, photometric and colorimetric measurements
Interfaces
The X1 features a USB interfaces.
