What are the maintenance and maintenance of portable hardness testers?

The portable hardness tester is a high-tech product integrating mechanical, liquid crystal, and electronic circuit technology. Like other precision electronic products, under our careful maintenance, its performance can be fully utilized and its service life is longer. Let me introduce to you how to maintain and maintain the portable hardness tester during daily use. There are roughly the following aspects.

The following is a list of contents:

Follow the operating procedures

Use environment

Wash more

Antifouling

Antiseptic

Anti-fall

Do not disassemble

Follow the operating procedures

The tester should abide by the operating procedures and be able to calibrate the portable hardness tester with standard blocks before and after the portable hardness tester test. If you do not use it frequently, you need to perform multiple hardness measurements on the standard after starting up, and then perform the measurement after the test piece is stable. Perform regular calibration, at least once a year, to ensure the accuracy of the portable hardness tester.

Use environment

The cleanliness of the use environment is the common requirement of all precision electronic products, and the portable hardness tester is no exception, and its requirements for the environment are higher than other products. The portable hardness tester should be placed in a dry and clean environment, away from damp places, and attention should be paid to indoor ventilation (used in a smoke-free place).

Wash more

Since the LCD panel of the portable hardness tester is very small, but the resolution is high, any small dust particles may affect the projection effect. Therefore, we must clean the dust filter of the air inlet frequently. Since the LCD panel is very sensitive to temperature, while preventing moisture and dust, the portable hardness tester in use should be kept away from the heat source to avoid damage to the LCD panel.

Antifouling

The portable hardness tester should be wiped with a soft cloth frequently during use to remove dust and dirt attached to the surface of the instrument, especially the supporting surface of the anvil and sleeve, and especially to prevent dirt from entering the gap of the dial or around the pressure needle. A large amount of dirt on the above components will affect the measurement accuracy or cause malfunctions.

Antiseptic

Although all parts of the portable hardness tester have undergone anti-rust treatment, some parts may rust if they are improperly maintained or used for a long time at the production site without paying attention to maintenance. Attention should be paid to the use of a portable hardness tester. In addition to frequent wiping, special care should be taken to avoid getting wet. Many parts will rust when exposed to water, and water in the meter head will rust and cause the meter to be scrapped.

Anti-fall

The portable hardness tester is composed of many precision parts. If it falls, some parts will be damaged.

Do not disassemble

The measurement accuracy of the portable hardness tester depends on the good cooperation of some precision parts. Therefore, except for the parts that are allowed to be disassembled during calibration, disassembly is not allowed.

The above is how to maintain the portable hardness tester to extend the service life. I hope it will help you. Pay attention to the daily maintenance of the portable hardness tester to extend the service life. The portable hardness tester is a precision instrument. Improper maintenance may affect the accuracy and performance of the instrument.
