The utility model relates to an universal meter specifically is universal meter pen -shape metre, solves present straight -bar style general purpose pen -shape metre and uses inconveniently when measuring the battery, need open repeatedly and close positive and negative pole protection lid, can't use in narrow and small space, easy problem of interfering with parts emergence on every side, the utility model discloses a realize through following technical scheme: universal meter pen -shape metre, including a body of insulating material parcel, with a nib part and a body angularity that body is connected. The utility model discloses it has following advantage to compare with present general purpose pen -shape metre: 1, simple structure, the current pen -shape metre of convenient utilization is reformed transform, 2, convenient to use need not to open repeatedly and covers positive and negative pole protection lid and can measure the battery, 3, the security is high, avoids operating the mistiming and touches the mistake and bump the battery and take place the incident.
