零位补偿区域
Zero compensation area
SF6-气体密度继电器/远传密度继电器带有零位补偿区域。仪表指针在无压力状态下，因为温度的升高或降低，会在零位补偿区域摆动，例如：60℃指针指示在低于零位的零位补偿区域下边缘，从而简单的测量出温度补偿值，当仪表温度降低,指针将移向零位补偿区域的正值区域。
SF6- gas density monitor /remote gas density monitor of this model has a zero compensation area. In the pressure-free state, the pointer swings within the zero compensation area due to temperature rise or fall. For instance, 60℃ pointer stays at the lower edge of zero compensation area below zero position and the temperature compensation value can be calculated in a simple way. When the instrument temperature falls, the pointer will move to a positive value of zero compensation area.
投诉/更换/修理
Complaint/replacement/repair
售后服务时请给出生产编号和产品型号,生产编号印在表盘上,产品型号印在标牌上。
At customer service, please provide with the production number and product model. The production number is printed on the dial, while the product model is printed on the nameplate.
SF6-气体密度继电器/远传密度继电器必须长时间恒温才能达到温度补偿作用(至少两小时) 。
偿作用(至少两小时) 。
SF6- gas density monitor/ remote gas density monitor must be kept in constant temperature for a long time (at least two hours) so as to achieve temperature compensation.
只有厂家可以进行维修,不允许开仪表,否则会使显示和开关点产生误差。
No one other than the manufacturer is allowed to disassemble the instrument for fear that any error may occur to the display and switch point.
安装
Installation
A．机械接口
Mechanical interface
一般仪表常用的技术性规范这里也使用 (如:En837-2),旋转安装时所用的力不允许直接作用到表壳或接线盒上,而是通过合适的工具作用到扳手面上.
Technical codes (e.g., En837-2) applicable to ordinary instrumentation also apply here. The force applied for rotation installation shall not directly act upon the instrument housing or terminal box but act upon the wrenching face through a suitable tool.

接线必须由经过培训的人员操作 .接线分布和开关功能都在仪表型号牌上给出,并注明了接线柱和接地柱.规定供电电线必须考虑仪表的大电流需求量并符合 IEC227 或 IEC245 标准.
The wirings shall be performed by professionally trained personnel. Wiring distribution and switching functions are displayed on the instrument type plate with terminal binding posts and ground pole also indicated. The specifications of power line must allow for the maximum current requirement of the instrument and comply with IEC227 or IEC245.
