The Ametek ASC-400 signal calibrator is a highly functional, portable calibrator that provides the functionality and accuracy you expect from a laboratory calibration system, but compact enough to fit into the tool box or operate with one hand for easy field calibration, process monitoring or maintenance functions.

The ASC-400 features an extremely user-friendly interface and high-contrast color display. Its unique "menu-free", single-window interface greatly simplifies operation, allowing all functions to be controlled or set from the main menu screen. The versatile instrument is capable of sourcing with simultaneous read-back from device-under-test of mA, V, pulsed transmitters, pressure and temperature.

The ASC-400 is more than just a signal calibrator. Combined with Ametek's APM external pressure modules, it becomes a true pressure calibrator with accuracies down to 0.025% of reading unaffected by temperature from -10°C to 50°C. When combined with a dry-block calibrator, it will calibrate temperatures.

The calibrator easily performs time saving functions such as automatic switch test, leak test, scaling and online % error calculation. It also is able to perform fast RTD simulation and works with pulsed transmitters and PLCs. Due to "True Ohm" measurement circuitry and CvD equations, the calibrator also can be used as a high-accuracy thermometer.
