YHS-715 process calibrator 
 YHS-715 process calibrator 
 YHS-715 process calibrator is an instrument used to calibrate the precision voltage and current signals and test tools. The calibrator for 0 ~ 24 mA current loop and 0 ~ 10V DC output voltage measurement and calibration, but not both use of measurement and output. 
 Input Resistance: 2MΩ (nominal value) <100pF over-voltage protection: 30 V 
 Overload protection: 125 mA, 250V fast blow fuse 
 Displayed as a percentage: 0% = 4mA, 100% = 20mA 
 Current source mode: found on the battery voltage ≥ 6.8V, 20mA when 1000Ω 
 (Battery voltage 5.8 ~ 6.8V, 20mA when 700Ω) 
 Analog mode: external loop voltage requirements nominal 24V, maximum 30V, 12V minimum
