No, è la taratura dell'amperometro. Se vuoi essere sicuro che la corrente sia davvero 0 puoi prendere la misurazione con un tester con pinza amperometrica o staccare il cavo del negativo dallo shunt (se continua a segnare 0.5 è taratura, se va a 0 c'è davvero corrente). Sul manuale trovi come settare lo 0. Questo è l'estratto:
SETTING THE ZERO-CURRENT
If no current is flowing into or out of the battery, and yet a small
residual current is shown on the display, the reading can be
adjusted to zero.
- Ensure that no current is flowing into or out of the battery.
- Turn off the unit.
- With the TIME key pressed, re-apply the power.
- Release the key. SET A is briefly displayed to show that the
zero current is to be changed. The TIME key increases the
setting, and the V&A key reduces it
- Adjust the setting until the value is shown as zero discharge.
(Note: several presses of the key are needed to change the
setting by 0.1).
- When the correct value has been set, turn off the power to
the unit to save the setting.
- Turn the power back on for normal operation
