1 General description
The multifunctional portable test instrument SigmaGT is intended to perform all
measurements for testing the electrical safety of portable electrical equipment. The
following tests can be performed:
- Earth bond / continuity resistance,
- Insulation resistance,
- Insulation resistance of isolated accessible conductive parts,
- Substitute leakage current,
- Substitute leakage current of isolated accessible conductive parts,
- Differential leakage current,
- Touch leakage current,
- IEC cord polarity test,
- Leakage and TRMS load currents with current clamp,
- Portable RCD test,
- RCD test,
- Functional test.
The instrument has a powerful test data management system. Autotests and single
tests can be stored (depending on the application) in approx. 6000 memory locations.
Some instrument's highlights:
- Large graphic LCD display with resolution of 240  128 dots, with back-light,
- Over 6000 memory locations in data flash memory for storing test results &
parameters,
- Three communication ports (USB and 2 x RS232C) for communication with PC,
barcode reader, RFID reader/writer and printers,
- Bluetooth communication with external printer, barcode reader, PC and Android
mobile devices (MI 3310A only),
- Soft touch keyboard with cursor keys,
- Built in real time clock,
- Built in calibration unit – checkbox (optional),
- Fully compatible with new METREL PATLink PRO PC software package.
Powerful functions for fast and efficient periodic testing are included:
- Pre-programmed test sequences,
- Fast testing with barcode, QR code and/or RFID tag identification systems,
- Test data can be uploaded from PC,
- Comparisons between old and new test results can be performed on site,
- Enables on site printing of test labels.
The operation of the unit is clear and simple – the operator does not need any special
training (except reading this instruction manual) to operate the instrument.
