?Increase disposable fast blow fuse, to avoid false instrument damage caused by voltage 220V plug.
? All functions all use internal electronic switch, input and output has a corresponding button.
? Two connector terminals can be used regardless of input and output. It is easy to operate.
? In addition to having a conventional signal input and output functions,resistance, PT100.Cu50 RTD, thermocouple eight kinds of signals can be input and output, measure negative temperature.
? The sensitivity of thermal resistance and resistance to external excitation output current is reduced. Increase the output and the measurement accuracy. For both constant and non-constant resistance measurement method, expanding the usage of the instrument.
