Introduction

The LKF-PERM series single/dual-channel extinction ratio meter can independently perform polarization extinction ratio test, optical power test, digital calibration, automatic range selection. There is a USB(RS232) interface for connecting with computer or manufacturing execution system (MES), and it is convenient for data collection and upload. It is widely used in optical communication equipment, optical fibre, optical passive device and optical active device testing, wide power range, high testing accuracy, cost-effective and reliable.

Calibration

In order to improve the accuracy, extinction ratio meter open calibration function, click 'CALIBR.' into the calibration mode, enter the password, you can adjust the size of the number through the up and down buttons, after the password is passed, enter the calibration menu. For the stability and accuracy of the instrument, the calibration function is not open to customers at present, if customers need, please contact us.

Security

In order to increase the service life of the instrument, the device is set with automatic shutdown protection function.
