YHS718 voltage and current calibrator (Volt / mA Calibrator) can be used to do calibration, repair and maintenance for those calibrated instrument which has 0-20mA loop current or 0-100mV/10V voltage signal, such as pneumatic actuators, electric actuators, hydraulic actuators, electric actuator mechanism, electricity - gas valve positioners and valve positioners, etc.

1. Rapid induction knob, Single-handed operation possible

2. mA current source output, simulation and measurement functions; showing the percentage of mA and range

3. mV/V voltage output, measurement functions; showing the percentage of mV/V and range

4. 0.02% accuracy and 1μA/10μV resolution

5. Steps and ramp output optional

6. 24V loop Power and processing mA measurement

7. Rechargeable management module built-in, able to charge while working1. Rapid induction knob, Single-handed operation possible

SOURCE mA mode: Calibrator outputs current

SIMULATE mA mode: Calibrator simulates an external power supply with a two-wire transmitter

Instrument outputs a high - precision voltage signal 0-100mV/0-10V; Voltage signal output resolution up to 10μV

The calibrator can periodically output a changing current / voltage signal applying to the external load or loop device continuously according to the time interval automatically.
