Q. What are some important considerations to make before purchasing a digital tong tester?

Answer

Here are some important considerations:Clamp meters should be tested for their safety features first and foremost. With a clamp meter the user's hands never come into touch with the conductor.A clamp meter with a digital readout will make testing a live high-voltage line much less of a hassle.The size of the clamp is also an important consideration. Since the longer clamp allows for easier measurement of longer wires this is a common accessory for electricians. Clamp sizes typically fall in the range of 17 mm to 45 mm. Pick one that works perfectly for need with little effort.
