Battery Pack Replacement - Fluke ScopeMeter 190 Series III User Manual

Alternatively, you may choose to exchange the battery (Fluke accessory BP290 or BP291) with a
fully charged one, and use the external battery charger EBC290 (optional Fluke accessory).

Battery Pack Replacement

To prevent possible electrical shock, fire, or personal injury, use only the Fluke
BP290 (not recommended for 190-xx4), BP291, or Fluke-recommended equivalent
for replacement.
When no adapter power is supplied, data not yet saved in the test tool memory is maintained if
the battery is replaced within 30 seconds. To avoid loss of data, do one of the following actions
before removing the battery:
• Store the data in the test tool (internal, non-volatile flash memory), on a computer, or a USB
flash drive.
• Connect the power adapter.
