When it may not be suitable

This device may not be the most cost-effective solution for hobbyists or individuals performing only basic household tasks that do not require high-precision measurements or CAT IV safety ratings. Additionally, users who require specialized features like data logging to a computer or advanced wireless connectivity may need to consider other models within the Fluke range.

Key specifications

• True RMS voltage and current measurements
• CAT IV 600 V and CAT III 1000 V safety rating
• Digital display with analog bar graph
• Integrated temperature measurement
• Manual and automatic ranging
• Frequency and capacitance measurement capabilities
• Resistance, continuity, and diode testing
• Min-max-average recording functionality

How to use

To begin using the Fluke 179, insert the provided 9V battery into the rear compartment. Connect the test leads to the appropriate input jacks based on the parameter you intend to measure. Use the rotary dial to select the desired function, such as voltage, resistance, or temperature. The device will automatically select the appropriate range, though manual ranging is available for specific needs. Use the display hold or auto hold features to capture readings in difficult-to-reach locations, and utilize the min-max-average function to track signal fluctuations over time.

What to consider before purchase

• Verify that the safety rating meets the requirements of your specific work environment
• Ensure the temperature measurement range aligns with your application needs
• Consider the need for periodic calibration to maintain measurement accuracy
• Assess whether the physical size and ergonomic holster fit your storage and portability requirements

Usage recommendations: Always inspect the test leads for signs of damage before each use. Ensure the multimeter is set to the correct function and range before connecting to a circuit to prevent damage to the device. Keep the unit clean and store it in its protective holster when not in use to prolong its service life.
