GM-2500V Adjustable High Voltage Digital Megohm Meter
Introduction
This instrument has high test voltage and strong output, and the measured object often has power frequency leakage or induction of high voltage interference electric energy, so for personal safety, the use of this instrument must first connect the safety grounding wire!
This instrument is designed and developed by our company to test the electrical insulation resistance characteristics of large high-voltage transformers, motor appliances, remote power cables or buried cables under the strong interference of high-voltage substations and power plants. It can also be used to measure electrical insulation resistance characteristics in a wide range of fields.
Features
1. Microcomputer control, menu operation, large-screen LCD dot
matrix display, stable performance, intelligent instrument.
2. Strong anti-interference ability, suitable for measurement in
strong electromagnetic interference environment.
3. There are four voltage output files: 250V, 500V, 1.0kV, 2.5kV.
4. Each high voltage can be adjusted continuously from zero.
5. Automatic measurement of R15, R60, R600, automatic calculation
of absorption ratio, polarization index.
6. Strong load capacity, short circuit current about 5mA.
7. The maximum measuring range is 0 ~5TΩ, and the measuring range
is automatically switched.
8. The analog bar pointer is combined with the digital display to
visually indicate the trend of data change and accurate measurement
results.
9. Display the test time at any time, and the buzzer automatically
sounds every 15 seconds.
10. After measuring, the high pressure is automatically released,
and the high pressure release time does not exceed 30 seconds.
11. Automatic measurement of ambient temperature, air humidity and
the date and time of each test.
12. Can save 60 groups of measurement results, and the data can not
be lost for 20 years.
13. Comes with RS232 serial interface, can communicate with
computer data.
14.5 minutes If no operation is performed, the system automatically
buzzes to shut down.
15. With comprehensive and perfect protection function, high
reliability.
