The Fluke 115C and 117C true‑RMS multimeter user manual provides safety guidelines, operation instructions, and specifications for both models.
This manual covers the Fluke 115C and 117C true‑RMS multimeters. It provides safety warnings, explains the VoltAlert non‑contact voltage detection, describes the display symbols, terminal functions, rotary‑switch positions, and operating modes such as Auto‑Volts, MIN MAX AVG, and Battery Saver.
Technical data are listed in the General Specifications, including a 6,000‑count digital display, 33‑segment bar graph, 9 V alkaline battery life, operating temperature range –10 °C to +50 °C, and input impedances of >5 MΩ (AC) and >10 MΩ (DC). The accuracy tables give the measurement limits for voltage, current, resistance, capacitance, and diode testing.

It shows the meter is in non‑contact voltage detection mode when the measured voltage is ≥ 30 V or an overload condition occurs.
Press the f button; the display freezes the current reading.
Hold down the g button while turning the meter on.
Press Q to toggle the backlight; it automatically turns off after 40 seconds.
