With the switch in the off position, connect the black probe to an earth point and the red to the positive input wire. "It has helped me to understand and reading the tester meter, I just need to take a little more time with this. For a digital multimeter the main difference is that the measurement type switch must be set to measure AC current rather than DC current. Position the function switch to read the maximum reading of 2000k ohms . And as an Amazon Associate we earn from qualifying purchases. This article does not replace the expertise of a qualified electrician. If you’ve hooked up, but the battery bank isn’t charging, use the multimeter to check if the outlet provides any voltage. Most of our electrical articles and all our installation posts refer to a multimeter. The reading doesn’t matter when only testing for continuity. A fluke digital multimeter features a large display screen and different collaboration functions. We’d love for you to join us! The complete accuracy is often calculated as +/- … When installing a campervan electrical system, you’ll use the handy tool all the time. Otherwise, the reading will display an error, depending on the multimeter model, indicating a break in the circuit between the two tested points. How do I use a multimeter to get a true reading? The Fluke 114 Electrician’s Multimeter is a good, middle of the range model, with all the features you’ll need for your campervan conversion. Unlike the other scales, the 0 (zero) value is on the far right instead of the left. Hey there!
