Output signal:V: 0-11.00V,mA: 0-24.00mA,mV: 0-110.0mV. Dimensions: 108 * 66 * 20mm. Power consumption: V, mV output 20 + hours, mA output according to the output current decision Self-protection signal generator:Built-in one-time quick-break fuse can avoid instrument damages caused by misinserting electric supply with 110V or 220V Signal Tester:Rational key layout, all functions have independent corresponding keys, which are easily to be operated. Fast speed and zero delay for key response It is characterized by safety protection with comprehensive in place and clear display. It adopts a brand shell and chooses grit finish, resistance soiling and anti-scratch. Its size is small and is easy to be carried High quality calibrator: Some key chips such as DA, reference voltage and operational amplifier adopts stable chips with high temperature and high temperature, to improve temperature stability of instrument and long-term aging performance index, Manufacturer: Huiouer
