Product Introduction
The UHV-680S Transformer Oil BDV Tester (Three Cups) is a comprehensive instrument designed to fully meet the requirement of measuring the dielectric strength of all kinds of insulating oil. It is controlled by a large-capacity single-chip microcomputer, ensuring stable and reliable operation. A wide-range internal watchdog circuit eliminates the possibility of system crashes, while the device integrates multiple safety functions including over-current, over-voltage, and short-circuit protection.

Product Characteristics
1. The instrument is controlled by the single chip microcomputer;
2. The instrument is equipped with a wide range of watchdog circuit to prevent the crash phenomenon;
3. A variety of operating options, the instrument program with GB1986, GB2002 two national standard methods and custom operations, can adapt to a variety of different users;
4. An instrument using special glass mold for one time, prevent the occurrence of oil spills and other interference phenomenon;
5. The unique high voltage sampling design of the device makes the test value directly into the A/D converter, which avoids the error caused by the analog circuit and makes the measurement results more accurate;
6. The instrument has the functions of over current, over voltage, short circuit protection and so on. It has strong anti-interference ability and good electromagnetic compatibility;
7. Portable structure, easy to move, both inside and outside the user is very convenient to use.
Matters needing attention
1. Before using this instrument, be sure to read this operation manual;
2. The instrument operators should be familiar with electrical equipment or analysis instrument of general use common sense;
3. The instrument is applicable to both inside and outside the home, but should avoid the rain, corrosive gas, high dust, high temperatures or direct sunlight and other places;
4. The oil cup should be kept clean.During the outage, should add enough dry qualified insulating oil immersion, keep oil cupwill not be affected with damp be affected with damp and oxide electrode;
5. Use after a month in a row, electrode should be routine inspection and maintenance. Check and adjust the electrodegap, make its restore standard; A magnifying glass to observe whether the electrode surface appear dark spots, if has this phenomenon, application of silk cloth to wipe the electrode surface, make its restore;
6. A professional instrument maintenance and debugging should be complete;
7. Before turning on the power supply, should check carefully whether the cable is firm, instrument shell must be reliable grounding.
8. After turning on the power supply, operators are strictly forbidden to touch the oil cup lid shell, lest produce an electric shock danger!
9. The instrument is in use process, if discovery is unusual should immediately cut off the power!
Simple troubleshooting
1. Boot no reaction：Check whether the power cord is plugged in properly and check whether the safety tube is intact;
2. No booster：Check whether the cap of the oil cup box is covered;
3. Normal wear without breakdown：Check if the setting limits the boost speed;
4. No display after breakdown：Check the oil cup for dirt;
5. The printer is out of paper：Check if the printer has any paper;
6. Replace the printer paper：The printer has been installed with printer paper. If the printing paper is used, new printing paper will be installed. The installation method opens the printer to put the paper bin, put the paper into the paper, extend a part. The printing paper light faces the direction of heat - sensitive tooth.
