The CR800 uses an internal voltage reference to routinely calibrate itself.
Campbell Scientific recommends factory recalibration as specified in
Specifications
(p. 91).

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.
The CR800 contains a lithium battery that operates the clock and powers SRAM
when the CR800 is not externally powered. Voltage of the battery is monitored
from the CR800 Status table ( LithiumBattery
(p. 543))
. Replace the battery as
directed in Internal Battery — Details
(p. 457).
The lithium battery is not rechargeable. Its design is one of the safest available
and uses lithium thionyl chloride technology. Maximum discharge current is
limited to a few mA. It is protected from discharging excessive current to the
internal circuits (there is no direct path outside) with a 100 ohm resistor. The
design is UL listed. See:
