2.1 Introduction
Thank you for purchasing JK500 series hand-held multi-channel temperature tester.
JK500 Series Handheld Multi-channel Temperature Tester is controlled by high
performance ARM microprocessor. It can collect multi-channel temperature data at the
same time, record the data on USB memory, alarm and communication transmission, and
can be extended to 128 channels of temperature data, compatible with a variety of
temperature sensors, fast response speed, and stable data. It also has the function of
even break detection.
The instrument is equipped with Mini-USB (Virtual Serial Port) interface. Data acquisition,
analysis and printing can be realized by standard computer software. It supports USB disk
storage and real-time storage of sampled data. Users can independently calibrate each
path.
