The Ashcroft ATE-2 calibrator is designed to measure pressure, temperature, voltage or current. It includes the capability to display up to two modules and one electrical measurement simultaneously, along with logging data to internal memory or communicating directly to a PC via USB connection. Product highlight IP65 / NEMA 4X enclosure Onboard 24Vdc loop power supply (non-intrinsically safe version) Optional intrinsically safe approvals (FM, ATEX, CSA) SD memory card slot USB interface 13 Engineering units of measure Large back lit display 180 Degree flip display Programmable damping Switch test function Percent error function Min/max recall Push-button zero adjust Tare function Hot swap capability Data logging allows the user to save pressure, temperature and or electronic values displayed on the LCD to internal memory. Internal memory can hold up to 64 data log files and a total of up to 16,000 individual records. Manual logging is initiated with a single key press. Automatic data logging can be programmed to collect data at timed intervals between 0.1 second and 24 hours. SD Memory Card Slot gives the ATE-2 additional data storage capability limited only by the capacity of the SD card installed. Data logs stored on the SD card are saved in .csv format which can be read by most spreadsheet programs. Data can easily be transferred from the ATE-2 to a PC. Loop Power Supply is a standard feature on non-I.S. units, and allows the user to conveniently power the device under test with 24Vdc up to 35mA. Percent Error Function can be used when calibrating pressure transducers. Calculations are performed by the ATE-2 eliminating potential for human errors. This function enables the user to program the full scale range and electrical output of the transducer under test and will display the actual pressure and electrical output readings as well as a percentage value comparing the actual output to the theoretical output. Switch Test Function allows the operator to calibrate and document the pressure switch function. The on-board display will show pressure switch trip point, reset point and will calculate switch deadband. All calculations are performed by the ATE-2 eliminating potential for human errors. Dual Mode Function allows the operator to add or subtract the measured pressure values from two installed Quick-Select™ pressure modules. This allows for measurement of “high-line” or elevated static differential pressures. This feature also offers the ability to add barometric pressure from an absoute pressure module to the measured pressure from a gauge pressure module, giving the use the ability to measure a variety of absolute pressures without using designated modules.
