Analogue meters take a little power from the circuit under test to operate their pointer. They must have a high sensitivity of at least 20k 
/V or they may upset the circuit under test and give an incorrect reading. See the section below on sensitivity for more details
/V or they may upset the circuit under test and give an incorrect reading. See the section below on sensitivity for more details Batteries inside the meter provide power for the resistance ranges, they will last several years but you should avoid leaving the meter set to a resistance range in case the leads touch accidentally and run the battery flat
Typical ranges for analogue multimeters like the one illustrated:
(the voltage and current values given are the maximum reading on each range)
(the voltage and current values given are the maximum reading on each range)
DC Voltage: 0.5V, 2.5V, 10V, 50V, 250V, 1000V.
AC Voltage: 10V, 50V, 250V, 1000V.
DC Current: 50µA, 2.5mA, 25mA, 250mA.
A high current range is often missing from this type of meter.
AC Current: None. (You are unlikely to need to measure this).
Resistance: 20 , 200 , 2k , 20k , 200k
AC Voltage: 10V, 50V, 250V, 1000V.
DC Current: 50µA, 2.5mA, 25mA, 250mA.
A high current range is often missing from this type of meter.
AC Current: None. (You are unlikely to need to measure this).
Resistance: 20
, 200 , 2k , 20k , 200k These resistance values are in the middle of the scale for each range
It is a good idea to leave an analogue multimeter set to a DC voltage range such as 10V when not in use. It is less likely to be damaged by careless use on this range, and there is a good chance that it will be the range you need to use next anyway
