When to charge
When powering the instrument from the battery pack without the Model Z1005
AC Adapter, the low battery icon (
) is displayed when the battery charge
is depleted, indicating that the battery pack requires charging.
Note that if the instrument is turned off under this situation, waveform data
may fail to be backed up, and could be lost.
Approximate charging time:
About 200 minutes at 23°C when recharged at the first appearance of the low
battery indicator.
Approximate continuous battery-only operating time
(When saving data to a CF card at a temperature of 23°C)
When using a USB flash drive, the continuous operating time may decrease
depending on the particular USB flash drive in use.
• After a full charge, with the LCD backlight always on (default setting):
approximately 2.5 hours
• After a full charge, with the LCD backlight off (five minutes after last key-
press): approximately 3 hours
Refer to “Enabling and Disabling the Backlight Saver” (p. 149).
