What setting should the multimeter be in to measure 220 volts?
A multimeter is a multi-purpose instrument often used for electrical circuit measurements. It is essentially an electromagnetic meter with a rectifier. It can be used to measure AC voltage, DC voltage, current, inductance, capacitance, audio level (output) and so on.
Notes on the use of multimeter
1. The range switch must be in the position of the measuring gear.
2. When measuring voltage or current, if the size of the measured voltage or current, the heart is countless, should be dialled to the maximum range test to ensure that the pointer will not hit the bad (pointer multimeter), and then dialled to the appropriate range test to reduce the error, but can not be charged with the conversion range switch.
3. In the measurement of the star direct voltage or DC current, must pay attention to the polarity of the instrument. Positive and negative terminals should be connected to the positive and negative terminals of the circuit, when measuring current, special attention should be paid to the circuit must be disconnected, the instrument is connected in series in the circuit.
4, about what you said, measuring 220 volts, to be clear whether it is AC or DC, according to you 220 volts, it may be AC, first of all will be the multimeter range switch dial to, greater than > 220 volts of the AC instructions to measure the gear, if it is measuring DC can be the range switch of the multimeter to the greater than the number of voltages you measure the DC instructions on the gear, you can measure. (Pay attention to safety when measuring AC to prevent electric shock)
If measuring AC 220V, the multimeter selects AC, the pointer meter selects more than 250V, and the digital meter selects more than 700V. If measuring DC 220V, select Dc, range select DC 250V or above, digital meter select DC 700V or above.
Various tables are not the same gear settings, but one thing is certain, set more than 220 volts of gear, DB98T digital display table has 20, 200, 750 volts of AC gear, to measure 220 volts of AC on the set of 750 volts of gear! Pointer MF500 meter has 500 volts AC gear.
