Appliance / Machine / Switchboard safety Appliance / Machine / Switchboard safety MI 3309 BT DeltaGT The MI 3309 BT DeltaGT is both battery and mains powered multifunctional instrument intended to perform measurements for testing the electrical safety of portable electrical equipment. Integrated unique PRCD testing technology prevents tripping out of mains RCD during measurement. Due to dual power capability of MI 3309 it enables performing of differential leakage current test in spite of its lightweight portable design. Large graphical LCD with backlight, two PASS / FAIL LED indicators and HELP screens for each measurement make the handling of the instrument clear and simple. Up to 1500 test results with parameters can be stored in the internal memory of the instrument and then downloaded to the PC for further data handling and creation of test report. Lightweight design, pre-programmed and custom test sequences, optional barcoding, android keyboard application and RFID systems make the MI 3309 an ideal instrument for high volume professional safety testing of portable appliances. MEASURING FUNCTIONS • Functional and visual inspection; • Earth bond resistance; • Insulation resistance; • Insulation resistance of isolated accessible conductive parts; • Substitute leakage current; • Substitute leakage current of isolated accessible conductive parts; • Differential leakage current test; • Touch leakage test; • RCD and portable RCD testing, type (K, S); • Power test; • IEC cord polarity test; • Leakage and load currents with current clamp; • TRMS voltage meter; • Enhanced TRMS test. KEY FEATURES • Autosequencing: pre-programmable VDE compatible autosequences, up to 50 custom prepared autosequences and barcode autotests speed up testing and ensure that no tests are missed. • Dual powered: the instrument can operate from mains power or batteries. • PASS / FAIL: large green and red lights for additional PASS / FAIL indication placed at the sides of the LCD. • Fixed appliance testing: additional inputs and optional accessories enable testing of fixed installed appliances. • Scan and test: optional QR or barcoding system and PASS / FAIL QR or barcode label printing make retesting quick and simple. • RFID: support for advanced RFID identification system. • RCD testing: instrument enables testing of parameters of RCDs and portable RCDs. • Memory: large data flash memory allows to store up to 1500 test results and parameters for further downloading to PC. • Built-in charger & rechargeable batteries: instrument has a built-in charging circuit and comes complete with a set of rechargeable NiMH batteries. • Bluetooth: enables communication with PC, printers, and android devices. • Android application: enables advanced data management, use of smart phones camera for scanning QR and bar-code. • PC SW Metrel ES Manager, included in the standard set enables downloading, viewing, printing of test results, creation of userdefined AUTOSEQUENCE®s, and exporting of data to spreadsheet applications. Printing of PRO reports and professional export to excel is available with a PRO license. APPLICATION • Professional GT safety testing; • General GT safety testing; • After repair GT safety testing.
