Multi-meter (Multimeter)
Multi-meter, that is a tool that measures necessary for the work on the transactions because it is a measure of the value of basic electrical voltage, current, and resistanceit was necessary to measure them as a multi-meter and Ohmmeter Ammeter Voltmeter as the same, and use มูฟเมนต์ (Movement) one called "VOM" (Volt - Ohm - Milliammeter)
The hierarchy using a CD-ROM, voltmeter
1 per PC. V while measuring pressure astride parallel to load
2. Use of downtown location, in downtown DCV
3.Adjust the switch located downtown Temple, do not know what is correct, if the mains voltage to the temple, the temple located downtown location maximum (1,000 V) before, and then to reduce downtown to a lower step-by-District until a needle meter will be pointed out. Easy-to-read and correct
4.in a good position at the temple, but it is not a voltmeter while you touch the positive measure to measure positive or when you pull the needle out, will always show that measure point to move a little. It is a voltage switch (ACV)
5.Measure the voltage at the circuit must be connected to the correct wire gauge, measure the negative (- COM), Black handle the negative of the power supply cable connector positive measure () red of the meter. To measure pressure on-the-spot
order of steps using ohm meter
1.Located downtown, the use of downtown ohm
2. Use a measure red plug into the connector to positive ( ) and the measured black plug it into the connector terminals minus ( -COM)
3. Small PC router switch located downtown Temple, right
4.Before the ohm meter to measure every time and every district will be required to make the adjustment. Always 0 ohm
5. If you use ohm meter to measure the resistance in a circuit must be sure that off (OFF) power switch every time
caution in multi-meter
1.Do not allow multi-meter with a prejudice, such as rain fell from the high, because it will give you the tools measure is damaged damage
2. should be put in place multi-meter flat (horizontal) when you use and disable
3.Before you make a measurement every time you need to make sure you select a valid measure of downtown always
4. Set up scale of downtown while the temple Wat that is not known,
5. Do not use downtown measure ohms measured voltage directly or AC
6.When you measure the voltage connector cable must be used to be measured - Always
7. When you choose downtown temple Wat ohm end-of-line should not touch, too long, and
8. After use should be removed from the temple area selection switch and adjust to the OFF
9.Do not allow multi-meter was born Overload (too much scale), while the temple often have to see the position of downtown temple Wat
good, with the circuit to be measured
10.A multi-meter is not used for a long time before you should turn Function Range and switch to reduce the deflation, and the
a good Electrical contact 11. should be stored in multi-meter, in the casing (Case)
always.
