Shenzhen large spot YHS302A process calibrator multimeter, YHS302A authentic guarantee, YHS302A Ram New YHS-302A process calibrator, YHS-302A process calibrator multimeter, YHS-302A process calibrator multimeter instrument ninety-nine, YHS-302A Shenzhen City on September Instrument Co., Ltd. Multimeter YHS-302A-type process is a set of digital multimeter and signal source function in one of the high-precision, high-resolution, highly reliable integrated digital hand-held instrument calibration, the output signal can be displayed simultaneously value and the measured signal value, with LED backlight for use in dimly lit places. Instrument AC-DC power supply can be more convenient to use. Instrument signal output and measurement functions are primarily designed for the implementation of on-site verification for the industrial automation field instrument maintenance needs. The instrument also has a multimeter function, is a field instrument engineering, computer distributed control system maintains an ideal tool for personnel, instrument fitter. It is different from common electrician multimeters and signal sources, is the instrument workers multimeter. The instrument has two channels, big-screen dual display - The upper display output, the lower display measurements. While the output side can be measured simultaneously displayed simultaneously. Realization of a machine. 24V power output meter separately. Instrument uses large-capacity rechargeable Ni-MH battery (with charger), with the common market, user-friendly replacement.
