What is multimeter
Digital Multimeter (DMM) is an electronic instrument used in electrical measurement. It can have many special functions, but its main function is to measure voltage, resistance, and current. As a modern multi-purpose electronic measuring instrument, a digital multimeter is mainly used in measurement fields such as physics, electrical, and electronics.

Clamp Meter
A clamp meter is a portable instrument that can directly measure the AC and DC current of a circuit without disconnecting the circuit. It is convenient to use and widely used in electrical maintenance. For example, clamp Ammeter can be used to measure the working current of AC motor in operation, so as to easily understand its working condition with load.

How to use a multimeter correctly and what details need to be noted

1. Mechanical zero setting before use
2. It is strictly prohibited to touch the metal part of the pen with your hands during use
3. Do not switch gears during the measurement process
4. Gear selection should be from large to small
5. When using a multimeter, it should be placed horizontally
6. Do not connect the positive and negative poles incorrectly

1. Before measurement, it is necessary to mechanically zero and inspect the appearance of the clamp gauge.
2. Choose the appropriate range, first select the large range, then select the small range, or estimate the nameplate value.
3. When using the minimum range measurement and the reading is not yet obvious, the measured wire can be wound several turns, and the number of turns should be based on the number of turns in the center of the clamp, then the reading=the indicated value × Range/full deviation × Number of turns
4. After the measurement is completed, the transfer switch should be placed at the maximum range.
When measuring, the measured wire should be placed in the center of the clamp and the clamp should be tightly closed to reduce errors.

Frequently Asked Question about multimeter
We are making our greatest efforts to offer you the quality made products at good price. We’d like to cooperate with you to expand our business in your markets.If in doubt, please see the following FAQ.
Our products were made in China, keeping pace with the increasing complexity of our customers’ needs, our engineers do many development in new models.
Step 1 – Turn on the device and allow it to cycle through its startup checks.
Step 2 – Turn the function selector switch to the “V=” position in order to measure DC volts.
Step 3 – Connect the red and black leads to the red input terminal marked “VO” and the black terminal marked “COM” respectively.
Step 4 – Measure voltage by placing the red lead on the terminal that has the higher potential and the black lead on the terminal with a lower potential or closer to the ground.
Voltage, Current, and resistance Range Or the range of specific features that you want to measure. No. of Counts- No of counts may vary from 1999 to no. of thousand. The one having more no. of counts is more reliable. Accuracy while measurement of Current, Voltage, Resistance. Sensing- Average or TRMS, TRMS give more accurate result as compared to Average type so for more accuracy one should go for TRMS type of Multimeter. Range of Temperature, Inductance, Capacitance should also be considered if you are measuring these parameters with a Multimeter.
