Process calibrator YHS302A 
 Process calibrator YHS302A 
 YHS-302A 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. 
 Whole circuit design from the 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 (4000 counts or 34 / 5), 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.
