Input: [header] How to test led lights [title] Purchase a digital multimeter that can take diode readings. [step] Basic multimeters measure just amps, volts, and ohms. To test led lights you will need a multimeter with a diode setting. <sep> (A) Check online or at your local hardware store for mid-to-high-range multimeters, which are more likely to have this feature than inexpensive models. [substeps] A decent mid-range multimeter will likely cost between $50-100 usd. (B) Choose an experienced technician to test you your multimeter's diode.

(C) This also depends on the model of your electronic device : [substeps] The brss tool-if you choose to examine the readings of your multimeter, then select " brss. " many digital multimeters can take diode readings anywhere between 30 milliseconds and 52.5 milliseconds. (D) Either purchase a multimeter at your local convenience store or get one with a screw-and-nut mount to safely measure the voltage and volts on, or even get a multimeter that uses the micrometer feature. [substeps] Review the label on your multimeter to make sure that it will not transmit a current.
