OXYMITTER DR PROBE
WITH ADAPTER FLANGE
NOTES: 1. HEATER TEMPERATURE SET TO 1380oF (750oC)
2.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. | 36210009 |
