Comtest, the sole authorised distributor of Fluke Industrial and Electrical test tools and Fluke Precision Measurement in southern Africa, announces the arrival of Fluke's new 5320A Multifunction Electrical Tester Calibrator. It is designed to simplify calibration processes and improve efficiency by incorporating the functionality required to calibrate and verify a wide range of electrical test tools in a single, easy-to-use instrument.
Using intuitive operation, the Fluke 5320A has a large, bright colour display, a graphical interface that shows users how to make terminal connections between the unit-under-test and the calibrator, and includes graphical help menus with calibration information. It features three standard interfaces for remote control, and supports MET/CAL Plus Calibration Measurement Software for automating the calibration process and managing calibration laboratory inventory.
Combining many functions into one instrument, the product enables users to verify and calibrate the following electrical testers:
* Multifunction installation testers. The 5320A has all the functionality needed to calibrate installation testers with voltage measurement, insulation resistance, continuity, loop, RCD and earth resistance test capabilities.
* Portable appliance testers. The 5320A has all the functionality required to calibrate PATs, with voltage measurement, insulation resistance, ground bond, leakage current, flash voltage and load test capabilities.
* Insulation resistance testers. Source high voltage resistors and measure the high voltage output of portable and bench insulation testers (megohm meters). To calibrate insulation resistance testers up to 1 kV, select continuously variable resistance values from 10 kΩ to 10 GΩ with 4-digit resolution and one single value of 100 GΩ. To calibrate 5 kV insulation testers, use the external 10 kV adapter to extend the resistance range up to 10 TΩ.
* Continuity testers and earth resistance testers. From the low-ohms function, source resistance values ranging from 100 mΩ to 10 kΩ with 4-digits of resolution.
* Loop/line impedance testers and ground bond testers. Source one of 16 high current resistance values to increase the resistance of a loop or line by a known amount for loop tester calibration. Use the Active Loop Compensation function to compensate for the resistance in the supply loop. For ground bond tester calibration, up to 30 A (40 A short-term) test current can be applied to the resistors.
* RCD (or GFCI) testers. The 5320A simulates an RCD (circuit breaker) to verify and calibrate trip time to an accuracy of 0,25 ms, and trip current to 1% accuracy.
* Earth and line leakage current testers. Simulate leakage current for direct/touch, differential and substitute leakage current tests with 0,3% accuracy from 0,1 mA to 30 mA.
* Voltmeters. Source voltage up to 600 V with 0,1 V accuracy to calibrate VAC and VDC meter readings on electrical testers (5320 A/VLC model only).
* Hipot testers. Measure voltage and current by using the built-in 1000 V meter and 30 A meter. Use the 10 kV adapter or 40 kV probe in combination with the built-in meter to measure hipot voltage and PAT flash voltages over 1000 V.
