YHS-202 process calibrator 
 Check calibrator YHS-202 
 YHS-202 process calibrator is a set of digital multimeter and the source functions in one high-precision, high resolution, highly reliable, hand-held integrated digital calibration instruments that can simultaneously display the output signal value and the measured signal values, with LED backlight for use in poorly lit places. Instrument for the AC and DC power, more convenient to use. 
 Signal output and the measurement instrument is mainly for the industrial automation field instrument-the-spot verification, maintenance needs and design. The instrument also has the function of the multimeter is a field instrument engineering, computer maintenance personnel distributed control system, instrument an ideal tool for installers. It differs from a common source of electrical multimeter and the signal is the work of the multimeters meter. 
 YHS-202 calibrator verification machine circuit composed by a large-scale ASIC chips. 8-bit microprocessor with an internal, high precision and high stability operational amplifiers and analog-digital converters. Low power consumption, showing high accuracy (20000 counts that is 4 1 / 2), automatic range, can reduce the operation and improve safety. Its technical performance in line with power II, Electric Type Ⅲ standard automatic instrument calibration, the working environment in line with GB6587.1-86 "environment for electronic measuring instruments Test Master" in the II group of the relevant provisions of the instrument.
