Metrel MI3310-25A SigmaPAT PAT Tester Details

The Metrel MI3310-25A SigmaPAT PAT Tester can be used to comprehensively tests portable appliances used in industrial, business facility management, and specialised sectors. For instance, it can be used in the following capacities:

  • As part of health and safety checks
  • Troubleshooting
  • As part of maintenance applications
  • Checking electrical equipment used in public areas
  • As part of fire safety checks
  • Verifying fixed wiring appliances
  • Multiple point testing of portable appliances
  • Fulfilling risk assessments
  • Testing portable appliances on construction sites
  • Checking equipment used by emergency services such as in fire brigade vehicles, medical sites and surgery rooms
  • Testing welding equipment
  • Checking electrical equipment that has been serviced or repaired
  • Checking electrical equipment contained in rental offices

To this end, the Metrel MI3310-25A SigmaPAT PAT Tester includes the following testing capabilities:

  • 10A earth bond resistance
  • 25A earth bond resistance
  • 200mA continuity
  • 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 tests
  • RCD and portable RCD tests for types AC, A and B
  • Functional tests
  • Measure leakage and load current (using an OPTIONAL current clamp)

When measuring the leakage current of power supply cables using an OPTIONAL current clamp the instrument-under-investigation does not need to be disconnected from its power source.

The Metrel MI3310-25A SigmaPAT PAT Tester includes a number of additional inputs which allow the user to verify fixed appliances. In addition to this, it is also compatible with a range of OPTIONAL accessories that also enable the testing of fixed appliances.

The Metrel MI3310-25A SigmaPAT PAT Tester’s scope-for-use is further expanded as a result of the tester’s innovative active polarity feature. This function allows the user to test RCD protected cords without removing the RCDs and while a voltage is being applied.

Test results are indicated on the Metrel MI3310-25A SigmaPAT PAT Tester’s large, bright, LCD display. Up to 6000 results (with parameters) can be saved to the Metrel MI3310-25A SigmaPAT PAT Tester’s internal memory.  

Saved data may be downloaded to an Android smartphone, Android tablet, or PC via Bluetooth. When downloading information to an Android smart-instrument, the Metrel aPAT App for data management is required (available through Google Play).  This app also allows the operator to use his/her smartphone camera as a barcode/ QR scanner.

The included Metrel PATLink Pro Software facilitates the user’s ability to upload and view data on a PC. This software can also be used to export results into spreadsheets and/or send information to print.

The Metrel MI3310-25A SigmaPAT PAT Tester is also compatible with Metrel’s more sophisticated software, the Metrel PATLink Pro Plus Software (NOT included) which allows the user to perform all the same tasks as the included PATLink Pro Software, as well as conduct more advanced analysis and create test reports. He/she can also use this advanced software to upload auto-sequences and historical data to the Metrel MI3310-25A SigmaPAT PAT Tester. Uploading historic data to the PAT tester enables on-site comparison and evaluation of the current and old data pertaining to the appliance under investigation.

Further to this, as a result of the Metrel MI3310-25A SigmaPAT PAT Tester’s Bluetooth communication capabilities, it can be used with Metrel’s compatible QR/ barcode scanners and printers. This enables faster testing as information contained within barcode/QR labels can be read using a compatible scanner and subsequently used to populate test fields. Once testing is complete the user can create an updated barcode/ QR label that is printed using a compatible Metrel printer. This method increases testing efficiency both in the long term and short term.

The Metrel MI3310-25A SigmaPAT PAT Tester’s ability to support pre-programmed VDE auto-sequences also improves testing efficiency. This PAT tester is able to accommodate up to fifty, customised auto-test sequences.

Despite the comprehensive and sophisticated testing capabilities of the Metrel MI3310-25A SigmaPAT PAT Tester, this instrument remains easy-to-use. It is equipped with integrated help screens and warnings which add to its ease-of-operation. To this end, it also features a QWERTY keyboard.

This lightweight tester also includes an integrated battery charger and may be powered using either the internal battery or a mains power supply (115V and 230V). This allows the user to tailor the Metrel MI3310-25A SigmaPAT PAT Tester to the application, again adding to its ease-of-use and its versatility.

The Metrel MI3310-25A SigmaPAT PAT Tester is a versatile, practical, downloadable PAT tester suitable for a variety of PAT checking applications across numerous industry sectors.
