1. During daily production, it is necessary to conduct spot checks on the instruments, and the instruments must be calibrated and operated by relevant personnel once a year
The operator should check that the instrument is used within its validity period.
2. Warm up the machine for at least 5 minutes after starting the test operation; Allow the instrument to be fully powered on and in a stable state
During the testing process, operators should not touch the positions or areas mentioned below; Otherwise, electric shock accidents may occur.
(1) High voltage output port of the tester;
(2) The crocodile clip of the test line connected to the tester;
(3) Tested product;
(4) Any object connected to the output end of the tester;
4. In order to prevent electric shock accidents, before using the tester for operation, during the testing process, the operator’s feet should be aligned with the large
For ground insulation, it is necessary to step on the insulation rubber pad below the operating table, and wear insulated rubber gloves before engaging in any work related to this tester
Close the job.
5. Safe and reliable grounding: There is a grounding terminal on the back board of this series of testers. Please ground this terminal. If not
When there is a short circuit between the power supply and the casing, or during the testing process, when the high-voltage test wire is short circuited to the casing, the casing will
The presence of high voltage is very dangerous. As long as anyone comes into contact with the casing, it is possible to cause an electric shock. Therefore
This grounding terminal must be reliably connected to the ground.
6. After the power switch of the tester is turned on, please do not touch any items connected to the high-voltage output port;
The following situations are very dangerous:
(1) After pressing the “STOP” button, the high-voltage test light remains on.
(2) The voltage value displayed on the display is not changing and the high voltage indicator light is still on.
When encountering the above situation, immediately turn off the power switch and unplug the power plug, do not use it again; Please contact the dealer immediately.
9. Regularly check the fan for rotation and do not block the air outlet.
10. Do not frequently switch on or off the instrument.
11. Please do not test in a high humidity working environment and ensure high insulation of the workbench.
12. When used in dusty environments, regular dust removal should be carried out under the guidance of the manufacturer.
If the instrument is not used for a long time, it should be regularly powered on.
14. The power supply voltage should not exceed the specified working voltage of the instrument.
15. If electronic measuring instruments encounter malfunctions during use, they should not be reluctantly used. They should be repaired before use, otherwise it may cause
Larger faults and adverse consequences, so we should promptly contact and consult our engineers
