PAT Review Metrel AlphaPAT MI2142

The Metrel AlphaPat has gained a reputation as a very durable and reliable PAT. It is a very user friendly PAT that is easy and quick to use. It is sold in various forms, from a stand alone unit to full professional kits with printer, scanners etc.

The Alphapat comes with 50+ preprogrammed test sequences that cover every type of appliance test you are likely to need, however in reality you will probably only ever need to use about 5 or 6 of them.  Once the testing is completed, the user can save the results and store details about the appliance including appliance description, location, retest interval etc.

Although the Alphapat doesn’t have a QWERTY keyboard, users will find the alphanumeric keyboard enables rapid control of the PAT due to the very responsive internal processors.

Pros

  • Easy to use
  • Compact
  • Very reliable
  • Performs all required tests, including 100mA, 10A & 25A earth continuity tests and leakage current tests, three phase testing ( requires adaptor leads etc ) and 15Amp appliance testing
  • Scalable to include a tag printer and scanner
  • Compatible with a number of software programs, including SimplyPats
  • “Double tag” function

Cons

  • Alphanumeric keypad
  • Keypad can require regular maintenance when used in high volume situations
  • No battery back up
  • Storage limited to 999 records, so requires regular full download and clearing of memory
  • No inbuilt RCD test function ( not a common feature when first released )
  • RS232 comms only – no USB connection (only required if downloading records to a software program)

Summary:

The Alphapat MI2142 is a fairly robust and reliable PAT that performs all the required tests as per AS/NZS 3760, including 15 amp appliances and three phase testing (with use of adaptor leads etc).  The “double tag” function enable users to test two appliances at once ie two leads, appliance with detachable lead etc. This is a real time saver, especially for high volume users but should only be used for a limited number of test functions.
The problem with the keypad requiring regular maintenance is disappointing for an otherwise super reliable and nearly indestructible PAT.
As a stand alone unit it’s a very portable and easy to use PAT that makes a great entry point for those with several hundred appliances to be done each round of testing.
Upgrading to include a printer is well worth the investment for those with higher volumes to test.

Overall 9/10
