Product Features:
1、High testing accuracy: The core components are imported, with high integration, precision, repeatability, and reliability. Due to its use of high-speed sampling A/D, it can not only measure density relays with conventional operating values, but also density relays with particularly small operating values.
2、The calibration process does not require a constant temperature chamber, and SF6 gas density relays and pressure gauges can be calibrated within any effective temperature range. By using pressure and temperature dynamic compensation algorithms, the pressure and 20 ℃ equivalent pressure values are automatically converted, and the pressure at the current temperature and the equivalent pressure at 20 ℃ are displayed, completely solving the problem of difficult on-site calibration of SF6 gas density relays.
3、Powerful function: capable of measuring density relays of different pressure types, both relative and absolute pressure density relays can be measured.
4、The initial state of the 1-3 sets of contacts in the density relay can be in any form (normally open or normally closed), and the up and down values of the 1-3 sets of contacts can be measured simultaneously, such as alarm, lockout, overpressure, etc. Therefore, this instrument can adapt to the fully automatic calibration of all new and old density relays.
5、Simultaneously displaying the current pressure and ambient temperature during measurement, solving the problem of on-site calibration of density relays.
6、Human computer interface friendly: equipped with a 7-inch high-definition full-color touch screen, easy to operate, beautiful interface, and all parameters and status are clear at a glance.
7、Complete supporting transition joints: This product is a portable instrument equipped with multiple types of transition joints. Most models of switch density relays can be verified on-site without disassembly, making it the best choice for SF6 density relay calibration.
8、Low gas consumption: During the verification process, the gas consumption is minimal, SF6 gas is not wasted, testing costs are low, and there is no pollution.
9、Support data storage: The instrument is equipped with a built-in large capacity memory, which can instantly save test results and has the function of saving power down data. It can query and print historical test data at any time.
10、Support printing: After the test is completed, all relevant test results can be printed immediately, and historical data can also be printed for analysis.
11、USB flash drive storage: supports USB flash drive storage of historical test data, which can be read through the supporting upper computer software for easy and fast operation.
12、Convenient to carry: The instrument is powered by a large capacity lithium battery and does not require AC power, solving the problem of difficulty in obtaining electricity outdoors. After the instrument is fully charged, it can work for a long time and can also be plugged into a charger to work at the same time.
13、Powerful PC software features: The accompanying PC upper computer application software is powerful and easy to operate, enabling data display, Word format saving, printing, and generating complete test reports for centralized data management.
14、Switching between Chinese and English: Customers can switch between Chinese and English on the main interface of the instrument, which can meet the needs of different customer groups, and other languages can be customized.

Note:
1. Before use, should check whether the power supply under-voltage, if under-voltage should be timely charging. Through the power on the instrument panel of 'power' 'charging' instructions exhibit of lanterns lit, after the battery is fully charge indicator lamp goes off.
Connect or disconnect the charger should first turn off the power , or may damage the instrument!!
If with printer please don't print when charging, in order to avoid over-load damage to power load. Long-term when not in use for 2-3 months should charge and discharge time, to extend the battery life.
2. Be confirmed before the calibrated meter without power in connection.
3. The instruments are precision instruments, in use, the transport process should avoid strong vibration.
4. The instrument self checking function is only for factory use.
5. It is strictly prohibited to use the gas source with impurities, and the test pipeline is strictly forbidden to enter the oil pollution.
6. The pressure of the portable SF6 gas cylinder is not more than 2.5MPa when gas filling.
