Percent Error Function can be used when calibrating pres- sure transducers. Calculations are performed by the ST-2A 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 pres- sure and electrical output readings as well as a percentage value comparing the actual output to the theoretical output. Leak Detect provides the ability to detect and quantify leaks in terms of pressure decay over time. In the pressure decay over time mode the unit will monitor the desired pressure vessel for the programmed time interval and, at the end of the monitoring time period, display the measured change in pressure. Switch Test Function the system can be used to test pres - sure and temperature switches. On board firmware provides the ability to verify switch trip points, reset point and to test the dead band of a pressure switch. Data Logging (Optional) Log up to 714 records on internal memory STANDARD FUNCTIONS

Manual Mode: An external reference junction may be used in place of the internal junction. External reference junctions may be applied in the temperature or direct millivolt readout modes. Resolution Reading in Temperature Units (selectable): 1, .1 or .01 degrees. “Auto” mode selection that allows the ST-2A to automatically configure the readout to the highest significant resolution (resolution closest to the tolerance) for the thermocouple type selected. Resolution Reading in Millivolts: .001 millivolts Thermocouple Connection (to interface module): Requires a “miniature thermocouple connector” (Omega type SMP), specifically matched to the thermocouple type to be used. These connectors may be purchased as an accessory under the following part numbers: (see how to order thermocouple connector table) SYSTEM ACCURACY (READING IN TEMPERATURE UNITS): Includes the base unit and AQS-TC1 interface module.
