The DPI 620 electrical calibrator can measure and source mA, mV, V, Ohms, frequency and a variety of RTDs and T/Cs. It provides an isolated 24 V loop power supply to energize devices and control loops and a stabilized dc voltage supply for ratio metric transducers. A HART digital communicator is provided for set-up and calibration adjustment of HART devices.
The high resolution, color touch screen of the calibrator shows only those buttons necessary for the immediate, selected tasks. The buttons have been sized so that they can be operated by a gloved hand, with no need for a stylus. The display can be configured to show up to six reading windows and each window can show an electrical input/output, pressure, temperature, a USB-connected device or a wireless-connected device. The reading windows also act as active keys and, when pressed, they expand to show more detailed information or to provide advance functions such as step and ramp outputs. Color is used to emphasize important information, for example, red for critical or failed values and green for pass or within tolerance.
The DPI 620 includes comprehensive documenting features for automating instrument calibration when used in conjunction with Intecal Calibration Management software.
