1. The pointer multimeter read less accuracy, but the process is relatively straightforward pointer swing, the swing speed range can sometimes be more objective measurements reflect the size (such as measuring the TV data bus (SDL) data in the transmission of minor jitter); number multimeter, intuitive readings, but the figures look very messy process of change, not easy to watch.

2. The pointer multimeter generally have two batteries, a low voltage of 1.5V, a high voltage of 9V or 15V, the black pen multimeterpen relative to the red side is positive. Electrical meters is commonly used a 6V or 9V battery. In the resistance profile, the pointer multimetermultimeterpen output current is relatively much larger number multimeter, with R × 1Ω file can make a loud speaker, "da" sound, with R × 10kΩ files can even light-emitting diode (LED).

3. In the voltage profile, the relative number multimeterpointer multimeterfor the internal resistance is relatively small, compared with less accuracy. Some high-voltage micro-current of the occasion can not be measured or even accurate, because of its resistance will affect the circuit under test (such as television picture tubes in the acceleration level measured voltage measurement is much lower than the actual value.) Digital sheet resistance of the voltage profile of the large, at least in the megohm level, has little effect on the circuit under test. But it vulnerable to extremely high output impedance of the impact of induced voltage, electromagnetic interference is stronger in some situations the measured data may be virtual.

4. Short, relatively high current high voltage analog circuits for measurement of the pointer multimeter, such as televisions, audio amplifiers. Small current at low voltage digital circuits for measurement of Digital thermometer, such as BP machines, mobile phones. Not absolute, and may be selected according to the situation pointer multimeterand Digital thermometer.

5. In measuring a current, voltage, can not be charged for select range b range, the first major election after election small as possible, close to the measured value of c measured resistance range, you can not live measurements. Because the measurement of resistance, the meter by an internal battery, if the measure is equivalent to access to live an additional power supply, may damage the meter. d with a complete, should make the maximum AC voltage switch gear or in neutral gear on. e Note that ohmmeter range change, the need for zero ohms, do not need mechanical zero.
