| One, overview Digital battery tester is a professional testing tool for the rapid detection of electric vehicle battery, motorcycle and car battery performance, suitable for 7AH 200AH lead-acid battery, and can also be the starting system of 12V car and charging system detection. A, structure characteristics: This product is composed of 7 - 20V and three and a half closed digital meter, high quality alloy resistance wire, high current automatic reset load switch, high quality crude copper wire, copper export type clamp, high corrosion resistant plastic rigid shell, direct digital display and battery voltage and load voltage no-load. Two, the technical parameters Battery specifications: 12V battery battery types: lead-acid battery Battery rated capacity: 7~200AH when measuring discharge current: 100A 12V battery Measurement of time: ≤ 3 second 12V battery Three, the use of methods Detection of 12V single battery: the tester red clip connected battery cathode, black clip connected batteries, such as reverse connection, voltage meter will protect not display, the tester display the no-load voltage of the battery, if the battery voltage is less than 12.4 volts, the power storage batteries after the above test, otherwise it will damage the battery. ② press load switch, digital display and battery voltage (12V battery as an example) Battery capacity Good or adequate power Generally charge Said poor charge Poor or no electricity 7AH More than 10.3V More than 9.6V More than 8.5V The following 8.5V 10AH More than 11.0V More than 10.2V More than 9V The following 9V 20AH More than 11.2V More than 10.5V More than 9.5V The following 9.5V 30AH More than 11.3V More than 10.5V More than 9.5V The following 9.5V 40AH More than 11.4V More than 10.5V More than 9.5V The following 9.5V 60AH More than 11.4V More than 10.8V More than 9.5V The following 9.5V 80AH More than 11.5V More than 10.8V More than 9.5V The following 9.5V 100AH More than 11.5V More than 10.8V More than 9.5V The following 9.5V 120AH More than 11.6V More than 10.8V More than 9.5V The following 9.5V 150AH More than 11.7V More than 10.8V More than 9.5V The following 9.5V 200AH More than 11.9V More than 10.8V More than 9.5V The following 9.5V Note: the battery load display: for multiple cell short-circuit 6~9 volts, over discharge. 0~6 volts for the battery breaker, broken. (the above for various brand batteries, old and new, the measurement data is also different) 12V starting system detection: the tester clamp connected to the battery, the red clip connected battery positive, negative black clip is connected with the battery, start the engine (no oil), then please don''t press the load switch, digital voltage display greater than 9.6V, the starting system, voltage display is less than 9.6V, the starting system problems The 12V charging system monitoring: the tester clamp connected to the battery, the battery positive red clip, clip is connected with the battery anode black, let the engine idle speed after the launch of go, do not press load switch, when the battery voltage is not less than 14V; If 13.80V can only charge 80% of the electricity; 14.00V can charge to 100%, and the electric water loss is minimum; 14.20V can charge to 100%, began to loss of the electric water; 14.50V can charge to 100%, and the loss of the electric water too much, the plate began to minor damage; 13.5V can only be filled to 60% capacity, long-term storage battery capacity sharply reduced. Less than 13.5V generally generator problems; higher than 14.5V for the general generator regulator problem. Four: Note 1 each test shall not exceed 3 seconds, so as not to shell heat hot, serious will burn out the instrument and load switch, the factory not warranty. Please pay attention to waterproof 2 instruments, anti dropping, man-made damage is not warranty. 3 battery liquid is not able to test, the best to wear protective gloves and goggles, accidents and hazards caused by wrong operation does not assume the user. 4 for the battery group should be segmented measurement, each battery voltage should not exceed 12V, such as the composition of electric vehicle battery generally consists of 3 - 4 battery, each battery performance measurement should be consistent, if found one battery inconsistencies should immediately picked to replace or repair. As the large diesel car 24V battery group, the surveyor should also be segmented detection. 5 load resistance wire with oil or dirt, after the first use will go up in smoke, is a normal phenomenon. |
