Professional electrical troubleshooting

The Fluke 177 is a true-RMS digital multimeter built for technicians who troubleshoot and repair electrical and electronic systems. Its 6000-count display provides precise readings for AC and DC voltage up to 1000 V. The meter includes min/max/average recording to capture signal fluctuations during diagnostics.

Rugged overmolded case with probe holders

The integrated overmolded body armor protects the instrument from drops of up to one metre and keeps test leads organised in built-in holders. Fused current inputs and overvoltage protection guard the meter internally, while the design prevents voltage measurement when the rotary switch is accidentally set to resistance. An easy-access battery door simplifies routine maintenance.

CAT IV 600 V and CAT III 1000 V safety rating

This multimeter meets IEC 1010 standards for measurement categories IV at 600 V and III at 1000 V, defining the electrical environments where it can be used safely. Buyers who need a higher category rating or additional functions such as capacitance or temperature measurement should verify those specifications before purchase.
