-50dBm to +26dBm is available. The 2498C/D optical power meter has two power meter modules, and only one of them can be selected at one time. Based on different optical source, it is divided into two types as shown in Table 1-1. - Page 5 Chapter I Overview However, it has self-discharging phenomenon. If the battery is stored at low voltage for a long time, it may damage the internal structure and shorten the service life due to self-discharge. Therefore, the lithium batteries should be charged every 3 to 6 months if they are stored for a long period of time. The lithium battery is a built-in battery and is stored along with the machine.
