Resistance ranges 400.0 Ω to 40.00 MΩ with resolutions from 0.1 Ω to 0.01 MΩ and listed accuracies; diode test to 2.000 V (accuracy 10 %, resolution 0.001 V); capacitance ranges 50.00 nF to 1000 μF with specified accuracies and resolutions; frequency measurement 50.00 Hz to 100.0 kHz (accuracy 0.1 % + 3). Input impedances and rejection: AC/DC voltage input impedance >10 MΩ <100 pF; exchange millivolts input impedance >1M, <100 pF with overload protection to 600 mV; common-mode rejection ratios listed (for AC/DC and mV ranges). Safety, protection and physical: IEC 61010-1: 600 V CAT III, pollution degree 2; highest voltage to any terminal and ground 600 V; current input fuse protection 11A, 1000V fast-melting type (use Fluke designated parts); protection level IEC 60529: IP 40. User-facing attributes: 6000-count LCD updated three times per second, two AAA batteries (NEDA 24A, IEC LR03) with at least 200 hours battery life, weight 200 g, volume 142 mm x 69 mm x 28 mm. Environmental limits: operating temperature 0 °C to 40 °C, storage temperature −30 °C to 60 °C, storage altitude 12,000 m, working elevation 2000 m, working humidity and 40 MΩ range humidity bands as specified; temperature coefficient 0.1 X (specified accuracy) / °C outside 18 °C–28 °C. Accuracy statement: Fluke 107 accuracy specified for one year after calibration when operating 18 °C to 28 °C and 0% to 75% relative humidity. Breaker-finder transmitter/receiver details: BK120 transmitter is line powered (110 V AC to 125 V AC at 6 mA), provides GFCI test and wiring check, and reports wiring indication with a 1 red / 2 green lamp pattern; transmitter rated frequency 50/60 Hz and safety rating CAT III 150 V. BK120 receiver is battery powered (2 AAA), provides NCV detection 90 V AC to 240 V AC, 50/60 Hz with dual sensitivity and visual/audio indication, gives visual and audio breaker-finder indication, includes a flashlight, auto power off and low-battery indication, and is rated CAT III 150 V. Receiver and transmitter combined support visual and audible tracing and basic outlet wiring diagnostic functionality. The combined kit is aimed at electrical technicians and maintenance teams performing circuit identification, breaker tracing and routine electrical troubleshooting in industrial and commercial buildings. The BK120 transmitter is installed or plugged into a branch circuit (110 V–125 V at 6 mA line-powered) to inject a trace signal; the handheld receiver locates the corresponding breaker or circuit in panels and distribution equipment using visual and audible indicators and NCV detection (90 V AC to 240 V AC). The transmitter’s GFCI test and wiring-check indications (1 red, 2 green) support quick outlet wiring verification during commissioning or fault isolation. The Fluke 107 multimeter provides compact, rugged verification and diagnostic measurements at the bench, in panels, or on machinery: verify AC/DC voltages to 600.0 V, AC/DC currents to 10.00 A, resistance, diode and capacitance up to 1000 μF, and frequency up to 100.0 kHz. Its 6000-count display, >10 MΩ input impedance, IP40 protection and CAT III 600 V safety rating make it suitable for control-panel, HVAC, and factory electrical maintenance tasks where portable, calibrated measurements and quick in-field checks are required.
