使用与订货须知 Notice for Using and Order

使用中若环境温度高，仪表指示不能回零，可用细针在仪表橡皮塞上通一小孔，使仪表内腔与大气相通即可。
使用环境温度：-25℃～70℃
使用工作频率不大于25Hz,振幅不大于1mm。
订货时请注明名称、型号、测量范围及工作温度。如有特殊要求，请明确参数，本厂可设计定制特种耐震压力表。

If the ambient temperature is so high that the gauge pointer does not return zero,in order to resolve it you may stick a small hole on the gauge seal with a needle,and the gauge inner will connect with the atmosphere.
Working condition temperature:-25℃～70℃

Working frequency is not to up 25Hz and amplitude of oscillation is not to up 1mm.
Please note name,model and measuring high limit on your order,and special filled pressure gauge can be provide on request.
