● Working environment temperature. 20 ° C~+50 ° C relative humidity: 45%~90%.

All circuits come with lithium battery packs, coaxial output load input, and can output continuous working time of 2 hours.
All external components are based on the RS-232C standard, and users can also add new standards.
LED with interface uses zero output voltage at high temperatures. Directly use a constant current when starting the machine. Start by measuring 0-33V. If there is no 0-5V, only R can be used.
