If you select wrong, it simply won't display a value, and you can select a different range. Choose the smallest value that is greater than your target. The same holds true for the other measurement types. If you chose the 200V setting, you would get 001.6 V. Notice that it's still correct, but you don't have the precision. The DSA500A Sperry Instruments Snap-Around Clamp Meter is a 5 function, 9 range auto-ranging unit engineered to measure AC Current (40-400A), AC/DC More. If you measured the same battery with the 20V setting, you will instead get 01.57 V. It may read back something around 1.567 V. If you were going to read a 1.5V battery, for example, you would choose 2000mV. You want to choose the setting that is higher than what you are measuring, and the closest. These values are the highest that can be measured. If you look at the DC Voltage ranges, for example, you have 200mV, 2000mV (same as 2V), 20V, 200V, and 500V. Your meter probably is able to display a "1", followed by three values from 0-9. The meter can only display a certain amount of characters, and so the different ranges effectively determine how many characters are before or after the decimal point. Numerical readout of DVMs is advantageous since it eliminates observational errors committed by operators. or d.c voltage being measured directly as discrete numerals in the decimal number system. The different range settings on your meter will give you different levels of precision. A digital voltmeter (DVM) displays the value of a.c.
