Safety Information and Precautions
Prioritizing safety is paramount when using the Fluke 117 Electricians Multimeter. Always adhere to these guidelines to prevent electric shock, personal injury, or damage to the meter or equipment. Use the meter only as specified in this manual. Familiarize yourself with all safety symbols and warnings. The Fluke 117 is designed for use in CAT III 600V environments.
Never apply more than the rated voltage between any terminal and earth ground. Inspect the test leads for damage before each use; replace them if insulation is compromised. Avoid working alone when performing electrical tests. Wear appropriate personal protective equipment (PPE), including safety glasses and insulated gloves. Do not operate the meter in wet or damp environments, or around explosive gases or vapors.
When measuring voltage, start with the highest range and decrease as needed to obtain an accurate reading. Disconnect the circuit power before connecting the meter. Be aware of high-energy circuits and take extra precautions. Never attempt to repair the meter yourself; refer servicing to qualified personnel. Ensure the battery door is securely closed before use. By following these safety precautions, you can minimize risks and ensure safe operation of the Fluke 117.
Operating Instructions: Basic Measurements
To begin using your Fluke 117 for basic measurements, ensure the meter is properly set up. Start by inserting the test leads into the correct input jacks; the black lead goes into the COM jack, and the red lead into the V jack for voltage, resistance, and continuity measurements. For current measurements, use the A jack, if applicable.
To measure voltage, turn the rotary switch to the V setting. Select AC or DC voltage as needed. Connect the test leads to the circuit, ensuring proper polarity for DC measurements. Read the voltage value on the display. For resistance measurements, turn the rotary switch to the Ω setting. Ensure the circuit is de-energized before connecting the test leads across the resistor.
To check continuity, select the continuity mode (usually indicated by a diode symbol). Touch the test leads to the points you want to test for continuity. A beep sound indicates a continuous path. The Fluke 117 features AutoVolt, which automatically selects AC or DC voltage based on the input signal. Always double-check your settings and connections before taking measurements to ensure accuracy and safety. Practice these basic measurements to become proficient with your Fluke 117.
Advanced Functions: Non-Contact Voltage Detection
The Fluke 117 boasts an advanced feature known as non-contact voltage detection (NCV), often referred to as VoltAlert. This function allows users to detect the presence of AC voltage without making direct contact with live wires, enhancing safety and convenience. To use the NCV feature, set the rotary switch to the VoltAlert position, typically marked with a specific symbol.
Hold the tip of the Fluke 117 near a suspected AC voltage source, such as a power outlet or wire. The meter will indicate the presence of voltage through an audible beep and a visual indicator on the display. The intensity of the beep and the display indication usually correspond to the strength of the detected voltage.
It’s crucial to remember that the NCV feature provides an indication of voltage presence but does not provide a precise voltage measurement. Always verify the absence of voltage using other methods, such as direct voltage measurement with test leads, before working on electrical circuits. The NCV feature is invaluable for quickly identifying live wires and ensuring a safer working environment. Familiarize yourself with its sensitivity and limitations for optimal use.
Measuring Capacitance and Frequency (117 Model Specific)
The Fluke 117 multimeter extends its functionality to include the measurement of capacitance and frequency, features particularly useful for electronics troubleshooting and circuit analysis. To measure capacitance, first, ensure the circuit is de-energized and any capacitors are fully discharged. Select the capacitance function (usually marked with a capacitor symbol) on the rotary switch. Connect the test leads to the capacitor, observing polarity if applicable.
The Fluke 117 will display the capacitance value in Farads (F) or its sub-multiples like microfarads (µF) or nanofarads (nF). For frequency measurement, select the frequency function (often denoted by Hz). Connect the test leads to the signal source. The meter will display the frequency in Hertz (Hz).
Note that accuracy can be affected by noise and signal quality. When measuring frequency, avoid frequencies above 1 kHz. The Fluke 117 automatically ranges for both capacitance and frequency, providing a convenient and accurate measurement experience. Always consult the user manual for specific range limitations and accuracy specifications for reliable readings.
Troubleshooting Common Issues
Encountering issues with your Fluke 117 multimeter? Let’s address some common problems. If the display is blank, first check the battery. Replace it with a fresh 9V battery, ensuring correct polarity. If the meter displays “OL” (overload), the input exceeds the selected range; switch to a higher range or use the auto-ranging function. For inaccurate readings, verify the test leads are securely connected and in good condition.
Ensure you’re using the correct function for the measurement type (AC/DC, resistance, etc.). If non-contact voltage detection isn’t working, confirm the function is enabled and the meter is close enough to a live conductor. Erratic readings can be caused by interference; try moving away from potential sources of noise.
If the meter fails to measure continuity, check the fuse and replace if necessary, following the manual’s instructions. If problems persist after these steps, consult the Fluke support resources for further assistance. Remember to always prioritize safety when troubleshooting electrical equipment.
Maintenance: Battery and Fuse Replacement
Proper maintenance ensures the longevity and accuracy of your Fluke 117 multimeter. Battery replacement is crucial when the low battery indicator appears. To replace the battery, first disconnect the test leads and turn off the meter. Locate the battery compartment, typically on the rear of the device. Use a screwdriver to open the compartment and remove the old battery. Install a new 9V battery, ensuring correct polarity as indicated in the compartment.
Fuse replacement is necessary if the meter fails to measure current. Before replacing the fuse, disconnect the test leads and turn off the meter. Access the fuse compartment, usually near the battery compartment. Identify the blown fuse and replace it with a fuse of the same type and rating as specified in the manual.
Incorrect fuse types can damage the meter or create a safety hazard. Always refer to the Fluke 117 user manual for detailed instructions and safety precautions regarding battery and fuse replacement. Regular checks and replacements are essential for reliable performance.
Calibration and Performance Verification
Maintaining the accuracy of your Fluke 117 is paramount for reliable measurements. Calibration ensures that the multimeter adheres to established standards, providing confidence in your readings. Regular performance verification helps identify any deviations from expected values, indicating the need for calibration.
Performance verification involves checking the meter against known voltage and current sources. Use precision calibrators to supply accurate signals and compare the Fluke 117’s readings with the calibrator’s output. Document your findings to track any drift over time. If the readings fall outside the specified tolerance, calibration is required.
Calibration should be performed by qualified technicians using calibrated equipment. Fluke offers calibration services to ensure your meter meets stringent accuracy standards. Calibration involves adjusting the internal components of the meter to align its readings with traceable references. Refer to the Fluke 117 user manual for detailed calibration procedures and recommended intervals to maintain optimal performance.
