Setup
1. Battery Installation (if not pre-installed)
The Fluke 115 typically comes with the 9V battery pre-installed. If replacement is needed, locate the battery access door on the back of the unit. Use a screwdriver to open the compartment, insert a new 9V battery, ensuring correct polarity, and secure the door.
2. Connecting Test Leads
- Insert the black test lead into the COM (common) input jack.
- Insert the red test lead into the appropriate input jack based on the measurement type:
- For voltage (V), resistance (Ω), capacitance, and frequency (Hz) measurements, use the VΩHz input jack.
- For current (A) measurements up to 10A, use the 10 A FUSED input jack.

Operating Instructions
The Fluke 115 features a large rotary dial for selecting measurement functions and buttons for additional features like HOLD, MIN/MAX, and RANGE.
Measurement Functions
- AC/DC Voltage (V∼ / V—): Select the V∼ (AC) or V— (DC) position on the rotary dial. The meter measures True-RMS voltage up to 600V.
- Resistance (Ω): Select the Ω position. The meter will display resistance in Ohms.
- Continuity (♫): Select the continuity position. A simple beep indicates when a wire or fuse is functioning properly.
- Capacitance (⊥): Select the capacitance position. Measures capacitance values.
- Frequency (Hz): Select the Hz position. Measures the frequency of AC signals.
- AC/DC Current (A∼ / A—): Select the A∼ (AC) or A— (DC) position. Measures current up to 10A (20A momentary for 30 seconds).
- Diode Test (→|—): Select the diode test position to check diode functionality.
Special Features
- Min/Max/Average: Press the MINMAX button to record signal fluctuations over time. This feature captures the minimum, maximum, and average readings.
- Hold: Press the HOLD button to freeze the current reading on the display.
- Range: The meter features auto-ranging. Press the RANGE button to manually select a measurement range if desired.
- Backlight: Press the backlight button (sun icon) to illuminate the display for work in poorly lit areas.
