3, the pressure source: the company offers a variety of pressure source for customer choice, customers can according to their own needs, equipped with pressure source device.
4, storage, printing, ZW - YF - 519 can store 50 meter calibration parameters, and can be generated automatically by the PC and print out the inspection report.
Applications:
ZW - YF - 519 seriesPrecision pressure checking instrument is a newly developed intelligent instruments, product appearance small and exquisite, full functions and beautiful, stable and reliable performance.The product can be widely used in electric power, petroleum, chemical industry, metallurgy, plastics, paper, medicine, food, environmental protection department of pressure calibration and measurement.
Four, the main features:
1, ZW - YF - 519 series precision pressure checking instrument for ac/dc handheld instrument.
2, high performance microprocessor performance and technical indicators of instrumentation for continuous correction, ensure instrument used for a long time, wide temperature range without affecting the precision of the instrument.
3, low power consumption.Battery USES the import nimh high-energy battery, ensure the instrument work in long time.
4, constant current charging, a charging battery voltage, under voltage automatic shutdown and automatic protection function, ensure the battery is not damaged by charging or owe voltage, long battery life.
5, micro power consumption under voltage automatic protection function, ensure instrument even if the operator and continuous boot for too long also won't because less damage to the battery voltage.
6 feature rich, full scale, one table is multi-purpose.
7, software, content is rich, the operation is simple, and clear.
8, the membrane panel light touch switch, novel styles, button long service life.
9, can be directly on the front panel adjustment full scale operation.
10, portable metal shell, strong anti-interference, strong impact resistance.
11, the structure of the integration, overcome the common checking instrument configuration and other using the defects of inconvenient.
Five, the technical parameters:
1, the current measurements: 0 ~ 20 ma F.S + / - 0.05%;
2, pressure measurements: 95.00 ~ 0 ~ 100.00 Kpa plus or minus 0.05% F.S (gas);
0 ~ 6000 kpa plus or minus 0.05% F.S (gas);
0 ~ 60.00 MPa plus or minus 0.05% F.S net water (liquid);
3, the output voltage: 24 VDC 50 ma + / - 10%;
4, battery capacity: 900 mah 7.2 V;
5, the machine power consumption: 2.5 W;
6, work temperature: 5 ~ 35 ℃;
7, storage temperature: - 20 ~ 60 ℃.
Six, the function keys and port details:
1, confirm: perform the function of the cursor refers to move a cursor;
2, backlight, backlight control button;
3, open/close: the power switch button;
4, storage: the current display data storage elm, according to the memory;
5, zero: eliminate the zero drift of pressure point;
6, 24 v: 24 VDC power supply output on/off;
7, bring about ▼ : the cursor keys to move up and down;
In a module, communication interface: the interface, and data output interface;
9, Iin: current detection current flow into the mouth;
10, Com: common end;
11, 24 v output instructions.

Seven, note:
1, the instrument should be placed in a clean, no corrosion environment, if you have special request, please indicate in the contract.
2, cannot use chemical solvents such as gasoline, alcohol scrubbing panel.
3, don't let the soldering iron and other heating element near the screen, in case of burnt plastic resin materials.
4, instrument has enough ability to overload, but do not serious overload, otherwise will cause the damage of the sensor, instrument cannot be used.
5, instrument is the seismic design, but still should be carefully handled very much, especially when used at the scene, avoid the fall, a collision.
6, instrument sensors are high precision products, silicon diaphragm don't collide with the solid surface, otherwise it will damage the sensor.
7, no professional testing skills and dedicated testing equipment, do not open the machine cover for maintenance, are not allowed to adjust the internal 8, and replacement material, otherwise there is no guarantee that the reliability of the instrument.
9, instrument need not when, should turn off the power supply, long-term need not when, charge once three months.
10, light with light, should be paid attention to avoid strong vibration stress check and avoid in corrosive gases or surrounding the humidity is very big, high temperature heat sources.
