TR2517 series multi-channel electropositive tester is a high-precision and wide-range automatic DC electropositive tester specially designed for multiple electropositive testing. Up to 30 resistors can be measured at the same time and displayed on the screen at the same time. Each channel has an accuracy of 0.05% and a range range of 1u~300K0, the number of display bits is four and a half digits, the test speed can be up to 12mS, the temperature compensation of the instrument can avoid the influence of ambient temperature on the test work, it has a very convenient sorting function, the Handler interface can output the sorting results of all channels without expansion, and can be equipped with RS232/USB/RS485 interface for remote control and data acquisition and analysis.

Features:
• Stand-alone mode and scanning mode can be switched at will to achieve dual-purpose use
• Supports up to 30 channels of scanning
• Maximum sampling rate of about 12ms/sec channel
• Highest resistance accuracy: 0.05%, minimum resolution: 10uQ
• Basic temperature accuracy: 02°C
• R, LPR, T and other test function combinations
• Support PT100 and PT500 temperature sensors
• Temperature Compensation (TC)
• Offset Voltage Compensation (OVC)
