What is the function and characteristics of the relay tester?
First, function 1. Relay protection tester can test a variety of AC and DC, current, voltage, room, self-hold, signal and other single relay and the whole set of relay protection screen, can test the various relays pull-in voltage (current Values, release voltage (current) value, pull-in time and disconnection time of various contacts (normally open, normally closed, changeover, delay) are automatically tested three times and stored, and the return of three mean values ​​is automatically calculated. Coefficient and print, can repeat display and print test results.
2. The relay tester can easily test the parameters of the reclosing relay.
3. Relay protection tester with frequency measurement, phase measurement function, can measure current, voltage frequency (display one cycle time, ie cycle) and phase difference (time) between two signals.
4. Relay protection tester has two independent channels, all insulated from other output of this machine, which can measure live contacts conveniently and meet the on-line test of relays. The wiring is simple and safe.
5. The relay tester uses a precise timing reference (10 microseconds) and up to 100 hours counter, so it can be used as a precision millisecond meter alone to replace the traditional stopwatch.
Second, characteristics 1. As the relay protection tester uses a microcomputer control, the panel has only 16 touch switches, you can easily complete a variety of test functions, change the old relay protection device must be turned off, switch a number of switches, In order to convert the power supply types, the operation is simple. Relay Protection Tester also has a self-test, error reporting function, which greatly facilitates inspection and maintenance.
2. Relay protection tester has a complete self-test, self-protection function, after the boot protection tester immediately put into self-test, in overload and over-range, the protection circuit will quickly cut off the output and emit a sound, light reminder, greatly reduced Unnecessary loss due to misuse.
3. The relay protection tester has a high degree of intelligence. By pressing only one key, all parameters of the universal relay can be measured, and all the data can be automatically printed, freeing you from cumbersome test operations.
4. The relay tester display has a function display unit that clearly reflects the working status of the unit from the display.
5. All data printed by the relay tester use Chinese characters, such as "suction voltage", "off voltage", "normally open suction time" and so on.
6. Measure the AC "live contact", after the security tester by the computer through a special circuit to determine whether the exchange of zero or contact action, so that the test is accurate.
Dear Customer:
Thank you for your attention to our products. In addition to this product introduction, the company also has insulation ladders, high-voltage insulation mats, cable fault testers, high-voltage measuring instruments, insulation boots gloves pressure test equipment, power safety equipment cabinets, etc. Introduction, if you are interested in our products, welcome to inquire. Thank you!
In the shopping mall, I saw that most of the goods were packed in tinned boxes, not only the common food, gifts, stationery and tea cans, but also cosmetics and health products. The tinplate box is very hard and airtight among many packaging materials
1. Good mechanical function: compared with other packages, tin cans have much higher strength, good rigidity and are not easy to break. It can be used not only for small sales package, but also for large delivery package.
2. Excellent sealing performance: tinplate cans have better sealing performance than any other materials. They are gas resistant, moisture-proof, light proof, and taste proof. They are also reliable and can be maintained to the maximum limit.
3. Offset printing precision: the printing function of metal materials is far better than other materials; Logo, pictures, words, etc. are very delicate and mellow in printing, which can more effectively avoid the appearance of paint falling and color fading.
4. Different shapes: tin cans can be made into various shapes according to different needs, such as square cans, oval cans, round cans, horseshoe shaped, trapezoidal, octagonal, etc., which not only satisfies the packaging needs of different products, but also makes the packaging of tin cans more changed.
In addition to the above advantages, the more important thing is that tin cans are green and environment-friendly products, which can be quickly recycled after use.
