Portable Appliance Tester
便攜式電器測試儀
Model : PAT320
The Megger PAT 320 PAT Tester is a simple, push-button portable appliance tester. That PAT320 is designed for customers who value speedy testing and do not require recording of test results.
In addition, the Megger PAT320 PAT Tester offers both manual and automatic portable appliance testing. In auto mode the Megger PAT 320 proceeds sequentially through earth bond, insulation and operation, indicating with an overall PASS or FAIL result.
