Megger-Hand-Held Appliance Tester Model-PAT 150

Megger-Hand-Held Appliance Tester Model-PAT 150

The PAT100 series of hand-held portable appliance testers enables simple, fast safety testing in all environments including offices, shops and business units. Its tough, reliable functionality is ideally suited for training organisations with high turnover, intensive courses.
With rubber armoured cases and hardened, scratch-proof glass, the PAT100s are exceptionally tough instruments.
Battery powered operation makes the PAT100s perfect for those locations where an electrical supply is not available, inconvenient or
unsafe, especially building sites and warehouses. The PAT100 series conforms to all UK and European requirements for electrical safety testing.

Test groups
Test groups enable the correct sequence of tests to be performed automatically with minimum intervention by the user. This keeps
testing simple, reduces test times to a minimum and helps to prevent testing errors.

PAT120:

• The PAT120 model has test groups available for Class I, Class II and Extension/Power leads.
• Fixed PASS limits.
• Insulation testing at 500 V (default) or 250 V can be selected at the start of the test.
• Leakage testing uses a “Substitute Leakage” also known as the “Alternative” method to remove the need for a mains supply
  during test.

THE PAT150:

• The PAT150 has additional tests available for testing portable RCDs (PRCDs) of 10 mA and 30 mA.
• Separate tests for continuity, insulation, mains powered leakage testing and SELV measurements can be made using the
  Quick Test (QT) button.
• Test group pass limits and test duration can be configured by the user.
• Bond lead resistance can be nulled to reduce measurement errors.
• Live circuit measurement is available for testing the mains supply and socket polarity or electrical circuit voltage to 300 V ac.
• Can be used for testing fixed appliances.

Continuity test
Used for measuring the proper bonding of all metal parts of a class I device to the protective conductor.
Tests are performed at 200 mA dc in both polarities to be compliant with international and UK regulation or recommendations. This test is safe to perform on equipment where higher test currents could cause damage.

Insulation testing
Used for measuring the separation of conductive parts or conductors from earth. This test is usually performed at 500 V dc. The PAT100 series maintains the necessary test voltage down to 0.5 MΩ.

Substitute leakage testing
Substitute leakage testing enables the measurements of AC leakage currents, which could differ significantly from the DC Insulation test results.
