This is a vibration meter that allows you to check the level on the main screen while simultaneously viewing the level waveform and other information on the sub-screen.
The VM53A consists of a PC-83C (three-directional vibration pickup) and a display unit. It can record three-directional measurement data to internal memory or a memory card (CF card). Additionally, by using the optional management software AS-60VM, data management can be performed on a computer. ■ It features two types of backlit LCD screens, with the large main screen displaying instantaneous values and the sub-screen showing various information such as level-time, bar graphs, and lists. ■ It is capable of continuously recording three-directional instantaneous values to a memory card, although the capacity of a single file is approximately 200 hours. ■ The maximum value, time rate level, and power average calculation results can be continuously stored in internal memory.
