Frequently Asked Questions
What is a clamp meter used for?
A clamp meter allows you to measure current by clamping around a live conductor without disconnecting it. It is ideal for electrical fault finding, maintenance work, and checking load currents safely.
What is the difference between the Fluke 303 and 302+?
The main difference is the AC current range. The Fluke 303 measures up to 600 A AC, while the Fluke 302+ measures up to 400 A AC. Both models share the same compact design and safety ratings.
What size cable can this clamp meter measure?
With a 30 mm jaw opening, it can clamp around conductors up to 30 mm in diameter, suitable for most standard electrical installations.
Is this clamp meter safe for industrial use?
Yes, it has a CAT IV 300 V / CAT III 600 V safety rating, making it suitable for industrial and commercial electrical environments when used correctly.
Does this clamp meter measure DC current?
No, this model measures AC current only. However, it can measure both AC and DC voltage as well as resistance.
