Safety Information
Always adhere to safety precautions when using the Fluke 179 Multimeter to prevent electric shock or personal injury. Read and understand all instructions before use. Ensure the meter and test leads are in good condition. Do not use the meter if it appears damaged or is not operating properly. Always use the correct terminals, function, and range for your measurements. Disconnect power to the circuit before making resistance, capacitance, or diode measurements. Wear appropriate personal protective equipment (PPE) such as safety glasses and insulated gloves.
Setup
Battery Installation
The Fluke 179 comes with a 9V battery pre-installed. If replacement is needed, refer to the 'Battery Replacement' section under Maintenance.
Connecting Test Leads
Insert the black test lead into the COM terminal. Insert the red test lead into the VΩmA terminal for voltage, resistance, capacitance, frequency, and low current measurements. For high current (10A) measurements, insert the red test lead into the 10A terminal.
Operating Instructions
General Operation
Turn the rotary switch to the desired function. The meter will automatically select the appropriate range for most measurements (Auto Range). Press the RANGE button to manually select a range if needed. Use the HOLD button to freeze the display reading. The MIN MAX button allows you to record minimum, maximum, and average readings over time.
Measuring AC/DC Voltage
Turn the rotary switch to V~ for AC voltage or V- for DC voltage. Connect the test leads in parallel with the circuit or component to be measured. Read the voltage value on the display.
Measuring AC/DC Current
Turn the rotary switch to A~ for AC current or A- for DC current. For currents up to 400mA, use the mA terminal. For currents up to 10A, use the 10A terminal. Connect the meter in series with the circuit. Ensure the circuit is de-energized before connecting the meter in series.
Measuring Resistance, Continuity, and Diode
Turn the rotary switch to Ω for resistance, continuity, or diode test. For resistance, connect the leads across the component. For continuity, the meter will beep if the resistance is below a certain threshold. For diode test, connect the leads across the diode and observe the voltage drop.
Measuring Capacitance and Frequency
Turn the rotary switch to the capacitance (∔) or frequency (Hz) function. For capacitance, ensure the capacitor is discharged before connecting the leads. For frequency, connect the leads across the signal source.
Temperature Measurement
Turn the rotary switch to the temperature (℃/℉) function. Connect the included temperature probe to the meter's input jacks. Place the probe on the surface or in the environment where temperature measurement is desired. The display will show the temperature in Celsius or Fahrenheit.
Maintenance
Cleaning
Wipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents. Clean the terminals periodically with a cotton swab and detergent. Dirt or moisture in the terminals can affect readings.
Battery Replacement
When the battery symbol appears on the display, the 9V battery needs to be replaced. Turn the meter off and disconnect all test leads. Remove the screw from the battery compartment cover on the back of the meter. Lift off the cover and replace the old battery with a new 9V battery. Replace the cover and secure the screw.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display or dim display | Dead or low battery; Meter off; Poor battery contact | Replace battery; Turn meter on; Check battery contacts |
| Incorrect readings | Incorrect function/range; Damaged test leads; Dirty terminals; External interference | Select correct function/range; Inspect/replace leads; Clean terminals; Move away from strong electromagnetic fields |
| No continuity beep | Circuit resistance too high; Meter not in continuity mode | Check circuit for open; Select continuity function |
