The instrument mode isolates the transmission port, with a loop resistance greater than 300 Ω. The voice alarm function can be turned on or off through interface options. The LCD backlight can choose energy-saving mode and automatically turn off at a fixed time. The high-performance CPU, high-precision AD conversion technology, and SMT chip technology complete multi parameter measurement, temperature compensation, and range conversion. The instrument has high accuracy and good repeatability.
