Using the Fluke 179-ESFP multimeter is a breeze. First, select the measurement type you need, like voltage, current, resistance, frequency, or temperature. You can choose between manual and automatic ranging. If you want to keep a reading on the display, use the display hold or auto hold feature. When measuring temperature, simply attach the appropriate probe. For getting minimum, maximum, and average values, the meter has built - in functions for that. As for the ergonomic case with the protective holster, it makes the multimeter easy to hold and protects it from minor bumps. When it comes to maintenance, keep the multimeter clean by using a soft, dry cloth. Don't expose it to extreme temperatures or humidity. Also, make sure to calibrate it regularly through the front - panel closed - case calibration feature. And always remember to turn it off when not in use to save battery life.
