How to use the UT612 universal meter

AC stands for AC, DC stands for DC, represents ohmic resistance value, MA current measurement gear, AC and DC gear can not be mixed by mistake, and the general gear is divided by a line frame. If you use AC500V for mains testing, you can't use a gear lower than AC200V. Misuse of DC file will burn the meter, although it will not be scrapped, but the performance and measurement results will be inaccurate, the current file, the measurement must be added to the load, between the measured and the multimeter.

You can't use the meter pen directly to ride, otherwise, good electrical components will be burned due to short circuit, if it is the mains, it is to burn the insurance trip, burn the multimeter and the meter pen line.

Product Introduction The UT612 is a stable, safe and reliable handheld 4 1 2 digit autoranging LCR digital bridge meter. It is a professional instrument for measuring inductance, capacitance and resistance, with the characteristics of low power consumption, high measurement accuracy and fast speed. Serial and parallel measurement mode selection, measurement components figure of merit, loss, phase angle, equivalent resistance measurement and DC resistance measurement, inductance, capacitance, resistance AC mode can provide five measurement frequencies (100Hz 120Hz 1KHZ 10KHZ 100KHZ), which can better meet the actual needs.

It can communicate with a PC, transfer measurement data, and save and print data and trend graphs through dedicated software. It is suitable for the measurement and screening of inductance, capacitance and resistance in laboratories, production lines, maintenance points and teaching, and is an ideal tool for maintenance for the majority of users.

Certification: CE, BSEN: 61326-1

Here's what it looks like. After turning on the phone, I saw that there has been a data transmission logo on the screen,(There is an S in the box,A few horizontal lines below)。 Because the automatic shutdown and data transmission cannot work at the same time, there is no transfer switch in this table, so there is no automatic shutdown function.

I saw someone in the altar modifying,Remember that it is like disconnecting the 112 pins of the main chip from the circuit,At this time, the icon of automatic shutdown appears on the screen,The data sending icon disappears,And then by installing an infrared sensor switch or a manual mechanical switch to convert,Some people simply give up the data transmission connection function in order to enable automatic shutdown (in fact, it is estimated that there are not many people who use this function、There are not many opportunities,I use 61e as a common meter,Do not automatically turn off the old to wake up,Need to play online with 71c and 289c)。

This has to be checked under a professional computer account to be executed, and it may be dangerous, so it can still be done before the professionals go down, and it can still be pretty good.

The most important thing is to have a calibration source, and the multimeter is not judged.

There are several potentiometers in it.

Yes, calibrate according to the corresponding function of Chadan, and it is recommended to hand it over to professionals.

Precautions before operation:

1.Press the power switch to check the 9V battery, if the battery voltage is insufficient, the "color" will be displayed on the display, then you need to replace the battery.

2.The " " symbol next to the test pen jack indicates that the input voltage or current should not exceed the indicated value, which is to protect the internal wiring from damage.

3.Before testing, the function switch should be set to your desired range.

Care and maintenance.

1.Do not connect to a voltage higher than 1000V DC or higher than 750V AC RMS.

2.Do not connect the voltage source when the function switch is in the current position, 2 and + positions.

3.Do not use this watch when the battery is not properly installed or the back cover is not tightened.

4.The battery or fuse should only be replaced after the test pen has been removed and the power supply has been cut off.
