三、使用须知
III Notice of Use
-
仪表适用于测量各类液体、气体及其它流体压力。上限不应超过3/4，测量波动压力时上限不应超过2/3，压力在两种情况下都不低于上限的1/3。
-
The instrument can be applicable to measure various types of liquid, gaseous, or other fluid pressure. Upper limit should not be exceeded to 3/4, when it applies to measure surge pressure, upper limit should not be exceeded to 2/3, and minimal pressure should be not less than 1/3 of the upper limit in both of two situations.
2.露天安装时，都应加遮雨装置
2. Rainproof set is necessary in open-air installation
3.仪表出厂时已加装了阻尼螺钉. 不要拆除。但被测介质急剧冲击震动时应加装相的YFN-01阻尼抗震器(选件)
3. All instruments are factory equipped with a damping screw, please do not remove it. When measured medium vibrates fiercely, YFN-01 suppressing vibration damper should be added to install. (Option Item)
4.为了仪表的安全，仪表供电应加装SAB-99电力线路避雷器及电涌抑制器(选件)。
4. For the instrument safety, the power supply should install SAB-99
Power line lightning arrester and surge suppressor. (Option Item)
5.仪表应装在和测量点同一水平线上，环境温度为0℃～+45℃，相对湿度不大于80%场合使用。当环境温度为-20℃～+85℃时仪表也可工作，但测量有所下降。超过85℃应配加T1专用散热器(选件)。
5.The instrument should be installed in line with the measurement point, which requires the environmental temperature is from 0℃～+45℃, and the relative humidity is not more than 80%. Under the range of -20℃～+85℃, instrument works but the accuracy decreases. T1 dedicated radiator should be installed when environmental temperature is above 85℃. (Option item)
6.仪表用直流电源DC:20V～24V、交流纹波＜5mV单台仪表按1.2W/24V～50mA计算
6. DC power for instrument use: DC:20V～24V AC Ripple＜5mV for each instrument 1.2W/24V～50mA
7.仪表供电必须正确，直流供电不能反接。
7. The power supply should be connected correctly, DC cannot be reversed connected.
8.不要自行拆卸仪表，人为造成的仪表损坏、雷击及电涌和过电压造成的仪表损坏、急剧的机械震动和水锤冲击造成的仪表损坏不属保修范围。
8. Do not repair or disassemble the instrument by yourself, damages caused by human error, lightening, electrophoresis and overvoltage, sharp mechanical vibration and water hammer , do not belong to the warranty scope.
