The coating thickness gauge can measure the thickness of magnetic or non-magnetic coatings (such as aluminum, chromium, copper, enamel, rubber, paint, etc.) on magnetic metal substrates (such as steel, iron, alloy and hard magnetic steel, etc.) ,and the thickness of non-conductive coatings (such as enamel, rubber, paint, plastic, etc.) on non-magnetic metal substrates (such as copper, aluminum, zinc, tin, etc.). It is a necessary meter for automobile manufacturing, sales, evaluation and metal processing, coating, inspection and other industries.

Press and hold the HOLD and ON/OFF buttons at the same time to disable the APO function. And “APO OFF” will show on the LCD.

FAQs

If the system language is Chinese after turning on the product, long press the Foreign Material Detection button (red) and the Power button (yellow) until the screen turns black. And then long press the Power button (yellow) to change the system language to English. To switch from English to Chinese, please follow the above steps.

FAQs

This is because the input impedance for mV measurement is high, typically at a level of GΩ, leading a strong drive capability to the voltage source. On the condition that the test leads are open, the induced voltage generating from ambient electromagnetic wave can easily be detected by the multimeter when performing mA DC or mV AC measurement, thus, it is normal that the displayed value can not be reset. The displayed value can be reset if the test leads are shorted.

FAQs

The accuracy is typically denoted in the percentage form of the reading, that is 1% of the reading, for example, if the measured value is 100V, the actual value may be between 99V~101V. But for technical parameters, the least significant digit will be counted into the accuracy, for example, if the accuracy is ±(1%+2) and the measured voltage is 100V, the actual value will lie between 99.8 and 101.2V.

FAQs

Ture RMS is a representation of non-normal AC signal.
Average Response Measurement: The average value multiplies by the waveform factor to obtain the value of AC signal.
True-RMS Measurement: The value of AC signal is obtained by the root mean square algorithm. For pure sine wave, accurate measurement can be achieved by average response or True-RMS; while for distorted waveforms or general non-sine waves such as square wave, triangular wave, sawtooth wave, an accurate measurement can be obtained by True-RMS only.

FAQs

The audion (Q1) at the PCB is broken down. Please send the product to the manufacturer for maintenance.

FAQs

1. Check if the USB function is started (There is symbol indication on the LCD)
2. Check if the software version supports the operating system.
3. Connect with other computers to check if the operating system is incompatible with the software.

FAQs

Poor contact of conductive adhesive at LCD screen due to impact or bumping. (Apply new conductive adhesive or send the product to the manufacturer for maintenance)

FAQs

The multimeter is protected by the fuse at current gear, it is also protected at voltage gear as it is able to detect voltage of 1000V and designed with internal resistance of 10MΩ. There is no fuse protecting the multimeter at resistance gear since voltage excitation source exits at resistance gear, the measured resistance is detected by detecting the current flowing through the measured resistance, if the voltage is measured at resistance gear, two voltage sources will crash, which may cause damage to the multimeter at resistance gear. Overload-protection circuit is also designed for the multimeter.

FAQs

The copper wire of the test lead may be broken, please replace the test lead with new one. Note: Do not twist the test leads.

FAQs

Generally, the specification of frequency accuracy is applicable to above 5% or 10% of the range, if below 5% or 10%, the accuracy will be affected, the affected value and the starting value of the range changes upon the models of products. For nonsinusoidal waveform measurement, please select a True-RMS meter and be sure that the range of duty cycle is 1%~99%.
