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.
