DMM help
|
Gold Member Username: OlegSanta Monica, CA USA Post Number: 1112 Registered: Nov-04 | I was looking at some DMMs at Fry's and RadioShack today and didn't understand what "8-range" meant and how that compares to 18 or 48 range or something like that. Can anyone clarify this for me? Also, what features is this thing supposed to have? |

Gold Member Username: Nd4spd18Southeast PA Post Number: 2154 Registered: Jul-06 | AC volts. The symbol looks like this: ~ If the meter is not auto-ranging, you set it to the next highest number from the value you will be measuring. For example if 40 volts is the value you're using to set the gain, and your meter has 2, 20, and 200 volts AC ranges, you would set it to 200. |
