THE GREATER MASS OF THE OXYMITTER DIRECT REPLACEMENT PROBE REQUIRES
LONGER TIME TO HEAT UP. UPON STARTUP, THE YOKOGAWA ELECTRONICS MAY
INDICATE AN ERROR BECAUSE THE PROBE HAS NOT REACHED TEMPERATURE SETPOINT
IN THE NORMAL TIME. REMOVE POWER FROM THE YOKOGAWA ELECTRONICS OR PROBE
MODULE TO CLEAR THE ERROR, AND RESTORE POWER. THIS PROCEDURE MAY HAVE TO
BE REPEATED A COUPLE OF TIMES BEFORE PROBE OPERATING TEMPERATURE IS REACHED.
