The new PIECAL 820 is smaller and easier to use than other multifunction calibrators. Six single function calibrators with advanced features are squeezed into a single surprisingly small package that fits into a pocket. This technician friendly calibrator is all about ease of use. An intuitive EZ-DIAL Double Click Menu makes it simpler to setup than larger calibrators with their complicated button filled panels and confusing menus. Use the PIECAL 820 right out of the box instead of wasting time learning to use more complex calibrators. The PIECAL 820 Process Calibrator combines all milliamp loop functions and sources and reads DC Volts and millivolts, 14 thermocouple types, 9 RTD curves, ohms and process frequency signals. For troubleshooting connections it has a continuity tester with tone. All ranges have auto storing MIN/MAX readings and three output set points for fast calibration of zero, midpoint and span.
