The Additel 209 loop calibrators combine user-friendliness and functionality with a wide range of applications. This makes them ideal for troubleshooting process loops. The ADT 209 has a measurement accuracy of 0.03% of the measured value. These devices are used for power supply, simulation, and measurement. The ADT 209 can be used to measure current, voltage, or pressure switches. It can also simulate and power a mA or process transmitter. With just one button press, you can switch between zero and span values, use the Auto Ramp function, or cycle through the range with the Auto Step function. Each loop calibrator features a large, easy-to-read display that simultaneously shows the measurement along with the percentage of the span.
