quick question about multimeter im buying?
i basically just have three simple questions:
1) is it ok for a multimeter to be able to read betwee 5A to 10A for only 15 secs in 15 intervals or something like that? i mean should it be longer?
and
2) there is a multimeter that has a frequency of 200Mhz and i know thats pretty big for a multimeter. i was wondering, though frequency is accompannied with oscilloscopes, can a multimeter with frequency be just as useful and if so how useful?
and
3) what is the usefulness of a multimeter being able to connect to a computer?
thanks
1) How often are you going to measure a current over 5 amps? If you plan on using the meter to measure large currents, I suggest you get a clamp on ammeter. DVM's use a resistance shunt that will start to get hot if you attempt to measure a current of 5 amps or more. This is why the meter says measure the current for 15 seconds or less and let it cool for 15 minutes.
2) D.V.M. multimeter do not have the necessary bandwidth to measure a frequency of 200 Mhz,at best they may be able to measure an AC of up to 200 kilohertz signal. There are RF power meters that will read RF.
3) Data logging for one
