8E3B使用介绍(二)

前面一节,我们介绍了8E3B的测量原理与如何接线,这一节我们来介绍怎么使用8E3B。

进入菜单之后,第一步可以对语言进行设定,我们可以根据我们的需求选择对应的语言。第二步进入显示/操作,进入之后里面还有许多选项,我们一步一步的进行演示。第三步是访问状态显示,可以看到显示的是操作员,输入密码之后也可以进入专家模式。第四步是进入显示,进入之后就是第五步。显示选项可以更改显示格式和显示对比度以及显示间隔,图中的显示对比度为一个值,然后是最大。第六步、第七步就是更改显示对比度。最后一步就是查看电流与频率。
各参数均对应唯一菜单编号,可通过现场显示单元直接访问。用户只需在密码输入项中录入访问密码,即可直接查看相关参数。
部分参数配备帮助文本,用户可通过菜单视图查阅。帮助文本简明阐述参数功能,有助于实现快速、安全的调试操作。
参数修改可通过数字编辑器或文本编辑器完成:
数字编辑器用于修改参数数值(如限定值等规格类参数);
文本编辑器用于输入参数相关文本(如位号名称等标识类信息)。当输入值超出允许范围时,系统将自动显示提示信息。
用户设置访问密码后,"操作员" 与 "维护" 两种用户角色将拥有不同的参数写入权限,以此保护设备设置,防止通过现场显示单元进行未授权修改。
设备出厂时默认未设置访问密码,此时访问权限(包括读取与写入)不受限制,默认对应 "维护" 用户角色。
现场显示单元中,参数名称前若显示锁形图标,表明该参数已通过用户密码锁定保护,无法通过现场显示单元修改其数值。键盘锁定后,整个操作菜单将无法通过现场操作访问,用户既不能继续查看操作菜单,也不能修改特定参数,仅能在操作显示界面查看测量值。键盘锁的开启与关闭可通过文本菜单操作完成。
以上就是该设备使用的一些基本介绍
