TL;DR True-RMS measurement with independent CAT III 600V certification (UL Listed, CSA, TÜV, VDE per Fluke 115 datasheet) · reads accurately on PWM automotive signals and household circuits where averaged-response meters give wrong answers. UL Product iQ was unreachable for database confirmation on 2026-05-26; the certification claim rests on the Fluke 115 datasheet and product listing until the database is reachable.
The Fluke 115 is a True-RMS digital multimeter carrying a CAT III 600V rating certified by UL, CSA, TÜV, and VDE per the product datasheet. It covers AC and DC voltage and current via a direct 10A path, resistance, continuity with audible beep, diode test, capacitance, and frequency · the complete set for automotive diagnostic and residential electrical work. The 6,000-count backlit display includes a 33-segment bar graph useful for tracking signal fluctuations on parasitic draw tests. Min/Max/Average recording captures drift during extended diagnostic sessions. Community reviews spanning 2012·2026 confirm accurate readings on modern vehicle circuits, and the Fluke 1xx series has served as a reference instrument in the electronics hobbyist community for 15+ years. The meter omits non-contact voltage detection and K-type temperature input, both available on the Fluke 117.
Home mechanics, DIYers, and anyone who needs a dependable meter for automotive circuits, residential outlets, and sensor diagnostics will find this meter accurate and well-built. The direct 10A current path handles alternator output checks, motor draws, and parasitic-draw testing without a clamp adapter. Skip it if non-contact voltage detection is a priority when identifying live wires before probing · the Fluke 117 adds NCV and LoZ ghost-voltage suppression but removes the direct current measurement path, so the right choice depends on which capability matters more for the work at hand.
The meter is declared CAT III 600V with independent certification from UL, CSA, TÜV, and VDE per the publicly published Fluke 115 datasheet; UL Product iQ returned HTTP 403 on 2026-05-26 and was not reachable for database confirmation at scoring time. Input protection for the Fluke 1xx series has been documented in EEVBlog teardown reviews of siblings (117, 175, 177, 179) as including MOV and transient suppression consistent with the CAT III rating; no arc-flash or fire incident has been documented in the community. Powered by a single 9V alkaline battery, accepted at Call2Recycle drop-off locations. The product carries a California Proposition 65 warning per the product listing.
The Amazon listing for Fluke 115 Compact True-RMS Multimeter carries a California Prop 65 warning. California requires this warning on a very wide range of manufactured goods — including electronics with wiring, solder joints, or plastic/metal housings — whenever trace exposure to any of roughly 900 listed substances (commonly phthalates or heavy metals) is possible, regardless of whether the specific product poses a meaningful health risk. As a passive electronics product, Fluke 115 Compact True-RMS Multimeter has no Safety Data Sheet, so there's no chemistry breakdown to translate beyond that.
