★The quantity display has a wide range of numerical values and can display 5-digit values: -9999 to 19999 Support vacuum Scientific notation display.

★Chinese menu configuration, display project tag number, and engineering unit. The software password lock ensures user configuration security. Built in national standard second level character library (6500 Chinese characters), using T6 Pinyin input method, freely inputting digits and units

★Alarm display, indicating the lower and lower limits, lower and upper limits, and upper and upper limits of each channel alarm. It can record the last 15 alarm records.

★Use USB interface to transfer and backup historical records, supporting 256MB, 512MB, 1G, 2G USB drives. Supports FAT16/FAT32 file system types, Windows can recognize history files

★Quasi serial communication interface: RS-485 and RS-232C

★Supports standard Modbus RTU communication protocol Provide multiple data types, such as percentage, engineering quantity, cumulative quantity, etc. In addition to supporting our company's ScanX data management software, it also supports popular professional configuration software such as Ifix, Kingview, MCGS, etc., without the need for dedicated drivers

★Can be connected to an external micro printer, supporting manual printing and timed custom printing, meeting the needs of users for on-site printing.

★Provide transmitter+24VDC isolated power distribution

★Rich compensation models can compensate for various media such as liquids, general gases, steam, and natural gas

★The small flow supplement metering function compensates according to the set value after the instrument loses power.

★Provide 8-hour shift reports, 12 hour shift reports, daily reports, and monthly reports. The accumulation time can be freely set.

★When the temperature sensor or pressure sensor malfunctions, it will automatically switch to the set temperature and pressure to calculate the compensation amount.

★It has a power-off recording function, which records the time of instrument power on and power-off, displays the cumulative power-off time, and prevents users from stealing steam during power outages.

★All aluminum sealed shell and internal shielding plate ensure the normal operation of the instrument in harsh environments
