WARNING:
Any damage made to the CRVW3 during user replacement of the internal battery is not
covered under warranty.
NOTE:
The battery is replaced during regular factory recalibration, which is recommended every 3
years.
When the lithium battery is removed (or is depleted and primary power to the data logger is
removed), the CRBasic program and most settings are maintained, but the following are lost:
l
Run-now and run-on power-up settings.
l
Routing and communications logs (relearned without user intervention).
l
Time. Clock will need resetting when the battery is replaced.
l
Final-memory data tables.
A replacement lithium battery can be purchased from Campbell Scientific or another supplier.
l
3 V coin cell CR2025 for battery-backed clock. 5-year life with no external power source.
WARNING:
Misuse or improper installation of the internal lithium battery can cause severe injury. Fire,
explosion, and severe burns can result. Do not recharge, disassemble, heat above 100 °C
(212 °F), solder directly to the cell, incinerate, or expose contents to water. Dispose of spent
lithium batteries properly.
NOTE:
The Status field Battery value and the destination variable from the
Battery()
instruction
(often called
Batt_Volt
) in the Public table reference the external battery voltage.
