![]() This means that the approximate magnitude of the signal does not have to be known or determined to take an accurate reading. On the Fluke meter the correct range is automatically selected for most measurements. On many multi meters each function also has multiple ranges for taking measurements of varying magnitudes. The multi meter has a multi position selector to select the desired function (See Figure 2). The functions on the fuse protected Fluke 73 multi meter are DC voltage, AC voltage, AC or DC current, resistance, audible continuity test and diode test. When using a multi meter and interpreting the results gained it is often useful to have a working understanding of Ohm's law. ![]() Diagnosing the ignition system on your car when it does not start after you have spent the day in the field in a remote location.Reading the voltage signal from pyranometer.Verifying power supply to a piece of equipment which is not functioning.Measuring the current draw of small AC or DC equipment.The meter could be used for all of the following, and much more. The specific applications of this device are numerous. A portable hand held multi meter can be used anywhere that quick accurate readings of voltage, current, or resistance are required. The meters feature an automatic hold to store a reading, and an audible continuity beeper, and can test diodes. These meters are over voltage protected against transient voltage spikes andĬonform to International Electrotechnical Commission's safety standard IEC 61010. The Engineering department at Humboldt has a set of Type 73 -III Series III hand held digital multi meter manufactured by Fluke. Fluke Type 73 Digital MultiMeter IntroductionĪ multi meter is small portable device that can be used to measure voltage, current resistance, or to test diodes.
