Optical Cap Overview
The RDO optical probe has an internal clock that counts down the 365 day
lifespan of a new optical cap . The countdown begins when the optical cap is
installed on the RDO probe, the probe is connected to the meter and the first
measurement is taken . The 365 day countdown cannot be reset or changed once
the first measurement is taken . Each optical cap has a unique serial number that is
recognized by the RDO probe, so reinstalling the cap will not reset the countdown .
Note:
The power to the meter must be turned off when a new optical cap
is installed on the RDO probe. Once the optical cap is installed, turn the power
to the meter on and the new cap information will be sent to the meter.
