The Ametek ASC-400 Signal Calibrator features a user-friendly interface and high-contrast color display. Its "menu-free", single-window interface simplifies operation, allowing all functions to be controlled or set from the main menu screen. The instrument is designed to meet the calibration demands of modern sensors and transmitters.

The ASC-400 is capable of sourcing with simultaneous read-back from device-under-test of mA, V, pulsed transmitters, pressure, and temperature. Combined with Ametek's APM external pressure modules, it serves as a pressure calibrator with accuracies down to 0.025% of reading, unaffected by temperature in the -10°C to 50°C range.

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

Input and output capabilities include RTD, thermocouple, current, voltage, frequency, pulse, and resistance. The ASC-400 is supplied with Ametek APM CPF Series Pressure Module for pressure calibration, ensuring comprehensive workload coverage. Weekly or monthly rental timeframes are available for flexible usage.
