charge condition of the storage batteries. The number of bars inside the icon is
proportional to the charge level.

No battery. The 8230 is supplied by external power unit.
When the capacity of the battery is too low, the message "Battery too low. The
instrument will be switched off soon" is displayed in the center of the screen. The
instrument is switched off 1 minute after this message appears.

2.5 Optical Interface

The optical interface (Figure 2-1, item 8) provides an optical, and therefore iso-
lated, two-way connection between the 8230 and a PC for transmission of the
information in memory (alarms, snapshots, motor starts, records) and all instanta-
neous measurements and waveforms displayed on the screen of the 8230.
The transfer rate is determined automatically by the 8230 according to the soft-
ware used; the maximum rate is 115.2 kbps.
