Using the Fluke 115 is quite straightforward. First, make sure you insert the two 9V batteries into the device. Then, attach the test lead set (TL75) to the appropriate ports. To measure voltage, current, resistance, frequency, or capacitance, just select the corresponding function on the multimeter. The large white LED backlight is great when you're working in dim areas, so don't hesitate to use it. When measuring current, be aware that it can handle 10 A AC/DC, but only 20 A for a maximum of 30 seconds. The Min/Max and average recording with display hold feature is handy for tracking changes over time. You can also use the Continuity Capture™ to record opens and shorts. The diode test function is useful for checking diodes. Remember to turn on the sleep mode when you're not using the multimeter for a while to save battery life. When it comes to maintenance, keep the device clean and dry. Avoid exposing it to extreme temperatures or moisture. If you need to store it, use the integrated holster. And always make sure the test lead set is properly stored to prevent damage. Also, since it has a CAT III - 600V rating, follow all safety guidelines when using it in electrical systems.
