Notes:
1. Heater temperature set to 1380°F (750°C)
2. The greater mass of the oxymitter direct replacement probe requires lohnger 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 operating
temperature is reached.
