YHS-718A电压电流校准仪(Volt /mA Calibrator)是对0—20mA回路电流或0-100mV/10V电压信号校准的仪器(如气动执行器、电动执行器、液动执行器、电动执行机机构、电-气阀门定位器和阀门定位器等)进行校准、维修和维护。新型的快速感应旋钮使其非常快速、易用、长寿命。电池采用了绿色环保型的可充电大容量锂电池!待电时间长,可节约大量运营费用!
主要特点有:
·使用快速感应旋钮,单手即可操作;
·mA电流源输出、仿真和测量功能;同时显示mA和量程的百分比;
·mV/V电压输出、测量功能;同时显示mV/V和量程的百分比;
·0.02%的准确度和1μA/10μV的分辨率;
·可选的步进和斜波输出;
·24V回路电源同时进行mA测量;
·内置充电管理模块,在线充电和开机工作可同时进行。
毫安电流输出模式
源输出毫安(SOURCE mA)模式,此时校准仪能输出电流。
模拟输出毫安(SIMULATE mA)模式,此时校准仪能模拟一个用外接电源供电的两线制变送器。
电压输出模式
仪表可以高精度输出0-100mV/0-10V电压信号,电压信号输出分辨率达到10μV。
自动斜坡电流输出功能
校准仪能自动按选择的时间间隔周期性的输出一个规律变化的电流/电压信号持续施加到外部负载或回路设备上,你仍可空出双手测试被测设备的响应。

Features
The fast, one-handed tool for loop checks.
This feature-rich solution combines the best features push-button and knob-base loop calibrator and offers:
- Large display and simple, quick-click interface for easy one-handed operation.
- Simultaneous mA and % readout for quick, easy interpretation of readings.
- mA accuracy of 0.025%,superior to other loop calibrators in this price range.
- 1 μA resolution for mASource,SimulateandMeasure.
- Innovative output adjustment dial with 1 μA and 100 μA resolution.
- 0-100%“Span Check”for fast switch between zero and full scale point.
- Selectable slow ramp, fast ramp, and step ramp to provide smooth outputs for valve slewing and loop functional tests. (Auto-Ramp Function provide single step(25%),slow or fast ramp output )
- 24 volt internal loop supply, so you can power and read a transmitter at the same time without carrying a DMM.
- Measures 0-10V DC & 0-100mV DC with accuracy0.02%
- Output 0-10V DC & 0-100mV DC with accuracy0.02%
- 4 - 20 mA or 0- 20 mAoutput range could be set manually.
- Rechargeable lithium ion battery pack.
- Push button 25% steps for fast, easy linearity checks.
