That 4-20mA 0-10V Current Voltage Calibrator is embedded with 2000-25000mAH rechargeable Li battery, low power consumption design, long stand-by time. It has micro USB port to charge battery, and large LCD screen with backlight can display parameters clearly. Adjusting methods of 4-20mA current simulation output: the international universal five points adjusting method and shortcut key, 0.1 and 0.01 step switching.
Current Voltage Calibrator Main Parameters
|Active current simulation output range:||0-21mA|
|Voltage simulation output range:||0-11V|
|Passive 4-20mA current loop simulation output:||Simulate various types of 4-20mA transmitter output|

Process Calibrator Operating Methods
>> Backlight: Press the two buttons on the right side at the same time , the backlight is on, then press again the backlight is off.
>> Press the two buttons on the left side at the same time to switch the adjusting step between 0.1 and 0.01.
>> Two buttons on the right side are add-subtract short-cut button; two buttons on the left side are step add-subtract short-cut button.
>> The button at the bottom function: active current, voltage, passive current switch.
