This product adds the function of the calendar and experimental data that can be preserved for a long time. The digital display is changed to liquid crystal display.

The controller of this product adopts a single chip microcomputer to test the entire process. The anti-interference performance of this product is very strong, completely overcome the current liquid crystal automatic tester vulnerable to high-voltage breakdown interference.

This product not only improves working efficiency, makes monotonous, repetitive, boring work become quite meaningful, but also safe, reliable, accurate measurement.

The function of this product is complete: 1. The stirring is automatic magnetic stirring, eliminating the unsafe factors existing in artificial stirring; 2. Can change the number of runs, stirring and static time at any time; 3. After the oil sample breaks down, there is a sound signal reminder, and the sound arrangement has a certain regularity. Through listening, it can also be known that it has been operated several times. If no audio cue is required, it can be turned off; 4. Configure miniature printers; 5. LCD display; 6. The voltage regulation system adopts a variable speed method, which is slow to rise and fast to return to zero; 7. Diversification of operating methods; 8. The calendar shows the time; 9. Long-term preservation of measurement data.

The operation of this instrument is simple: except for the first time you need to press the pre-set to the data you need(if measured by the national standard, this step can be saved, because the data has been pre-set by the national standard at the time of delivery. The number of times is 6, the stirring time is 1 minute, and the static time is 5 minutes. After that, only press the value key. The diversity of modes of operation is designed for the different needs of users.

This instrument is suitable for testing dielectric strength of various insulating oils. Its main performance characteristics are as follows:

1. The instrument has the function of automatic detection, such as automatic start-up into reset state to execute voltage regulator return to zero.

2. The micro TPU-A panel printer is used to print out automatically.

3. According to the user's needs, it can change the test times, stirring, static time, sound-controlled light-controlled reminder continuous printing and non-printing.

4. The instrument uses full-automatic magnetic oscillator stirring to eliminate the non-uniformity of oil samples and bubbles.
