YHS-707 process calibrator 
 YHS-707 process calibrator 
 YHS-707 process calibrator is the current loop calibration, repair and maintenance. 
 High-performance solutions. Rapid induction of new knob makes it quick and easy to use, long life. 
 YHS-707 process calibrator main features are: 
 ? Use of rapid induction knob can be operated with one hand 
 ? MA power supply, simulation, and measurement functions 
 ? 0.025% accuracy and resolution of 0.001mA 
 ? Also shows the percentage of mA and the range 
 ? Optional step and ramp output 
 ? 24V loop power supply, the mA measure, including the HART resistor 250Ω 
 ? 0-28 DC voltage measurement? Openings can not easily replace the battery 
 ? Compact design structure, with a removable protective cover.
