Documenting Process Calibrator

Information

Fluke 701 and 702 Documenting Process Calibrators (hereafter referred to as the calibrator) are battery- powered, hand-held instruments that measure and source electrical and physical parameters. See Table 1. The Calibrator lets you troubleshoot, calibrate, verify, and document the calibration of process instruments. See the back of this manual for complete specifications. In addition to the functions in Table 1, the 701 and 702 calibrators have the following features: · General features: Analog display in measurement mode to make it easy to read the input level when the input is unstable. Display shows information in English, French, German, Italian, or Spanish. Thermocouple (TC) input/output jack that is connected to an internal isothermal block with automatic reference-junction temperature compensation. Or, you can manually enter an external temperature reference. Stores results for later review. Logs up to 8,000 data points (model 702 with PMLink Software only.) PC Interface for uploading/downloading procedures, lists, and results using PMLink Software (model 702 only). Automatic calibration procedures for transmitters using split screen MEASURE/SOURCE mode. Once you select the test parameters, you can select an automatic procedure or you can execute the test points one at a time. · Features available in MEASURE mode: Damping (smoothing of the last several readings). Display of measurements in engineering units or percent of scale. Data logging (model 702 only). • Features available in SOURCE mode: An output ramp feature for testing limit switches. Trip detect is either a 1V change or a continuity status change (Open or Short) from one ramp increment to the next. An output step feature in which you set the step size and press up or down to step the output in engineering units or percent of scale.
