FAQ
What does CAT III 600 V mean?
CAT III 600 V indicates the multimeter is certified to safely measure voltages up to 600 V in distribution circuits such as panel boards, circuit breakers and wiring in commercial and industrial settings.
Can I use the Fluke 17B+ for HVAC temperature checks?
Yes. The included type‑K thermocouple allows temperature readings from -200 °C to 400 °C, making it suitable for heating, ventilation and air‑conditioning diagnostics.
How often does the battery need replacement?
The multimeter runs on two AA batteries and typically lasts several hundred hours of intermittent use. An auto‑power‑off feature helps conserve battery life when the device is idle.
Is the multimeter suitable for automotive work?
While the 17B+ can measure up to 1000 V, it is primarily designed for low‑voltage residential and commercial applications. For high‑current automotive diagnostics, a dedicated automotive tester is recommended.
What warranty does Fluke provide?
Fluke offers a standard one‑year limited warranty covering defects in materials and workmanship, with options to extend coverage through authorized service plans.
