How to use MF47C multimeter to measure DC voltage How to use 40

MF47 multimeter measures and measures DC voltage: the maximum allowable measurement voltage of its ordinary board surface is 1000V. Another special terminal with a measuring voltage of up to 2500V (not recommended for general operators).

1. The maximum rated voltage of the circuit to be tested is required to be consistent with the maximum measurable voltage of the multimeter. 2. Before measuring, check whether the multi-purpose surface and the table pen are normal. 3. When measuring, the red watch pen is connected to the positive pole.

The black meter pen is connected to the negative pole of the DC voltage, when the value of the measured voltage range is unknown, the range of the multimeter should be adjusted to the maximum value, to see whether the gauge needle is between 2 3 and 1 3 of the full scale range of the surface, if it is not in this range, or the pointer moves a little to the right, it means that the range is too large. Adjust the range down until the pointer is between 2 3 and 1 3 of the full scale of the surface to accurately reflect the actual value of the measured voltage. 4. When measuring, the multimeter must be placed flat, and when observing the reading, it should be facing the surface.

Keep the line of sight, pointer and scale in a straight line to avoid measurement errors.

Measure DC voltage:

MF47 multimeter.

There are mainly nine DC voltage gears. When measuring the DC voltage, first estimate the size of the measured DC voltage, and then turn the transfer switch to the appropriate voltage range (the DC voltage of the multimeter is marked with "V" or marked with the "DCV" symbol), connect the red meter rod to the measured voltage "+" end, that is, the high potential end, and the black watch rod to the measured voltage "-" end, that is, the low potential end. The voltage to be measured is then read out according to the selected range and the number of the pointer on the scale DC symbol "DC" tick mark (the second line of the dial).

For example, when measuring in the DC 500V range, the size of the measured voltage can be read up to 500 volts. For example, when measuring with DC 50V, the maximum value of the voltage measured by the multimeter is only 50 volts.

Turn the gear switch of the multimeter to the DC voltage level 500VDC. The red pen is connected to the positive pole. The black table pen can be connected to the negative pole of the DC voltage. If the measured DC voltage value is too small, you can choose a smaller DC voltage level.

Scale multiplier, a total of 50 squares. 50V is read directly, 250V is multiplied by 5, 10V is multiplied and so on.

MultimeterAlso known as multiplex table, multi-purpose meter, three-purpose meter, multi-use meter, multi-use meter, etc., it is the most basic tool in the field of electronic testing, and it is also a widely used test instrument. It is composed of three main parts: the meter, the measuring circuit and the transfer switch. Generally, the main purpose is to measure voltage, current, and resistance.

According to the display mode, it is divided into pointer multimeter and digital multimeter. It is a multi-functional, multi-range measuring instrument, generally the multimeter can measure DC current, DC voltage, AC current, AC voltage, resistance and audio level, and some can also measure AC current, capacitance, inductance and some parameters of semiconductors.

The basic principle is to use a sensitive magnetoelectric DC ammeter (microampere meter) as the meter head. When a small current passes through the meter head, the multimeter will have a current indication.

MF47 multimeter measurement 380V voltage methodHello dear, put the meter in AC 500V gear, two meter pens each by a phase line, read the dial marked with a red "10VAC" engraved line of the scale, multiply the reading by 100 is the actual result. On the table, one large cell is 100, one small cell is 20, and 380 is 3 large and 4 small cells. Hope it helps.

Does MF47 multimeter measure AC and DC voltage without batteries? The resistance setting requires a few batteries, and the AC 220 is measured with an additional electric indicator of 260V

Dear, you are glad to answer for you: MF47 multimeter measures AC and DC voltage without batteries? The resistance setting requires a few batteries, and the AC 220 is measured with an additional electric indicator of 260V

Answer: MF47 multimeter is mainly a battery for resistance gear, 2 batteries, and 9V, the battery for small resistance resistance is enough to make the meter head full scale, but to measure the resistance of large resistance, especially above five or six hundred K or even on the mega, the voltage can not meet the needs of the full scale, so it is necessary to use 9V high voltage. I hope mine can help you, I wish you a happy life, if mine is helpful to you please give me a 5 star praise Oh, thank you for your support to me.

MF-47 pointer multimeter 500 volt AC voltage gear voltage scale how to convert.

Dear, hello, I am happy to answer your question, how to convert the 500 volt AC voltage scale of MF-47 pointer multimeter. Answer: The gear should correspond to the modulus of the chant.

For example, whether it is current or voltage, if you use a 50 unit gear, the reading will look at the line with a full scale of 50. 2. Because, the scale of the fierce cherry blossom can be read proportionally, so, like the 500V gear, you can see the line of 50 full scale, and the reading is multiplied by 10. The others are just enviable.

Extended information: Precautions The multimeter is a relatively precise instrument, and if it is not used properly, it will not only cause inaccurate measurements but also be easily damaged. However, as long as we grasp the use of the multimeter and the precautions, and do it carefully, then the multimeter can be durable.

When using the multimeter, the following matters should be noted: (1) The measurement of current and voltage should not be rotated into the wrong gear. If the electric barrier or current is mistakenly blocked to measure the voltage, it is very easy to burn the meter.

When the multimeter is not in use, it is best to turn the gear to the highest AC voltage to avoid damage due to improper use. (2) When measuring DC voltage and DC current, pay attention to the "+" polarity and do not connect it wrongly. If you find that the hands are reversed, replace the watch rods immediately to avoid damage to the hands and head.

3) If you don't know the size of the voltage or current to be measured, you should use the highest gear first, and then choose the appropriate gear to test, so as to avoid excessive deflection of the watch hand and damage to the meter head. The closer the selected gear is to the measured value, the more accurate the measured value will be. Hope it helps.
