Explanation:
① 2~ 4 measurement channels, independent display. Addition, subtraction, average, multiplication, and division operations function and maximum, minimum determination function
② basic error is better than ± 0.2% F · S. 16 bit A / D converter for measuring speed of 0.2 seconds / per channel
③ anti-jamming design, inhibit the rapid burst interference relays, contactors, etc. produced by the scene and other electromagnetic interference, immunity to level III
④ Input signals include: thermal resistance, thermocouple, DC current, DC voltage
⑤ Dimensions: 160 * 80 (horizontal / vertical)
⑥ instrument power 220V AC. (9~ 30) V DC
basic configuration
2-channel input, dual display
extensions
