I.The instrument features
1. The instrument is controlled by a large capacity single chip
microcomputer, which is stable and reliable;
2. The instrument is equipped with temperature, humidity and clock
display functions, and can be customized for infrared oil temperature
measurement.
3. The wide range watchdog circuit is set in the instrument to prevent the
crash;
4. A variety of standard options. The instrument program is equipped with
GB / t507-1986, GB / t507-2002, dl429.9, iec156 and self programming
operation, which can adapt to a variety of choices of different users;
. The oil cup of the instrument is made of special glass and high polymer
materials, which are processed finely to prevent oil leakage and
corrosion;
6. The unique high-voltage sampling design of the instrument allows the
test value to enter the A / D converter directly, avoids the error caused
in the analog circuit, and makes the measurement result more
accurate;
7. The instrument has over-current, over-voltage, short-circuit and other
protection functions, and has strong anti-interference ability and good
electromagnetic compatibility;
8. Can switch between Chinese and English at will to meet the needs of
any customer;
9. 232 The data transfer；
