Product description
Safety and construction: The FS899L prioritizes user safety with IEC CAT.III 1000V and CAT.IV 600V ratings, double-fuse anti-burn protection, and overload safeguards. It carries CE and RoHS markings and is built in an impact-resistant plastic housing with drop protection to preserve operation after accidental knocks.
Measurement capabilities: This True RMS multimeter supports up to 6000 counts and handles AC/DC voltage from 60 mV to 600 V, DC and AC currents from 300 mA up to 10 A, resistance up to 60 MΩ, capacitance from 10 nF to 60 mF, plus frequency and temperature readings. Non-contact voltage detection (NCV) and continuity checking are included for quick circuit checks.
Display and usability: The meter features a large 4.8-inch color display with backlight and an integrated torch to aid work in dim panels and confined areas. Auto-ranging and automatic detection streamline measuring—simply attach the probes and the instrument will select the appropriate mode. A data-hold function freezes readings for awkward test positions.
Power and runtime: Modern USB-C rechargeability eliminates disposable batteries. A two-hour charge typically yields around eight hours of continuous operation, making it convenient for prolonged diagnostics in workshops, field service, and home projects.
What’s in the box: The package ships with one multimeter, two test leads, one instruction manual, a USB-C charging cable, and the retail packaging box. Materials listed are plastic and metal; the unit is offered in standard size and available in red or black. Optional model variants include FS899C and FS899S, the latter being the color-screen edition.
After-sales support: The manufacturer offers customer assistance—if the unit doesn’t meet expectations, contact the seller to arrange a replacement or refund.

Mixed experience, check the probe port
First unit was stuck in auto mode and was replaced. Note: the manual’s probe port guidance was misleading for me; using the right-hand input fixed the reading.

Simple to operate, reliable readings
I don’t use meters daily, so simplicity matters. This model cuts out most button fuss, feels light, and reads accurately. Kept my old unit as backup.
