Figure 3 - Voltage and Current
Figure 3 shows the display when the V&A key is pressed. The
present battery voltage and battery current, as well as the
estimate of the state of the battery's charge are shown.
The maximum current measurement is 102 Amps.
If the BM-1 Compact is left for long periods registering little or
no charge or discharge current, the estimate of capacity may
become unreliable. It is important to switch some load onto the
battery for a few minutes so a reliable estimate can be calculated,
and its value settles, before starting charging.
SETTING UP
Setting up can be done after applying power to the unit while one
of the keys is pressed. This procedure prevents inadvertent changes
being made by an unfamiliar user. Applying power is usually most
easily achieved by removing the fuse for a few seconds, and then
re-inserting it. When the setting is finished, removing the power
again returns the unit to normal operation when power is re-applied
with no key pressed.
