This manual introduces the features and usage methods of the Fluke 115C and 117C True-rms multimeters.
The Fluke 115C and 117C are battery‑powered true‑RMS multimeters with a 6000‑count display and analog pointer. The manual covers both models, using the 117C for all illustrations, and explains compliance with CAT III IEC 61010‑1 safety standards. Safety sections detail warnings, proper use of test leads, and precautions for high‑voltage work.
Key features include multiple measurement functions (voltage, current, resistance, capacitance, frequency, diode), a VoltAlert non‑contact voltage detector, auto‑range and manual‑range modes, MIN/MAX/AVG recording, display hold, backlight control, and a sleep mode that activates after 20 minutes of inactivity. Detailed specifications for each function are provided in tables throughout the document. This manual is written in Chinese.
| Safety Category | CAT III |
|---|---|
| DC Voltage Range | 0.001 V – 600 V |
| AC Voltage Range | 0.06 V – 600 V |
| DC Current Range | 0.001 A – 10 A (20 A overload 30 s) |
| AC Current Range | 0.1 A – 10 A (20 A overload 30 s) |
| Resistance Range | 0.1 Ω – 40 MΩ |
| Capacitance Range | 1 nF – 9999 µF |
| Frequency Range | 5 Hz – 50 kHz |
The Y symbol appears when the meter detects a voltage of 30 V or higher or an overload condition, warning of dangerous voltage.
The meter offers both Manual Range and Auto‑range modes; in Auto‑range the instrument selects the optimal range automatically, while Manual Range lets you choose the range yourself.
