Burnoff

 

When a probe is in a furnace, soot will collect in the end of the probe, which will have a negative effect on the performance of the probe.  Burnoffs are used to clean out the built-up carbon by burning it off of the probe.   Burnoff:  Clicking on this value allows users to manually initiate burnoff procedure.  The user will have to confirm this action   Configurator – Confirm burnoff   The “Test Status” will show that a burnoff is in progress.

 

Impedance Test:

Clicking on this value manually turns on/off the impedance test (this can only be initiated manually). This test lasts 30 seconds.  The user will have to confirm the action.

 

Configurator – Confirm impedance test

 

The “Test Status” will then become “Impedance Test”.

 

Cancel:

Clicking on this value will manually turn off both the burnoff and the impedance test.  The user will have to confirm this action.

 

Configurator – Confirm cancellation

 

Next Burnoff: (shown in minutes):

This value is a displayed calculation based on the burnoff time set in the Probe Burnoff Setup menu option.  It displays the number of minutes until the next burnoff will be initiated.

 

Test Status:

This value displays the current testing status.  The list of possible values are: Burnoff, Burnoff Recovery, Idle, Impedance Recovery, or Impedance

 

Timer:

This value shows the remaining time, in seconds, for the Burnoff / Impedance Test / Recoveries.

 

mV:

This value is a display of the current millivolt input value during a burnoff or impedance test.

 

TC:

This value is a display of the current probe thermocouple input value during a burnoff or impedance test.

 

Start mV:

This value is a display of the millivolt input value at the beginning of the Burnoff or impedance test.

 

Start TC:

This value is a display of the probe thermocouple value at the beginning of the burnoff or impedance test.

 

Last Burnoff:

This value shows the date and time of the last burnoff.

 

Last Impedance Test:

This value shows the date and time of the last Impedance test.

 

Last Recovery:

This value is a display of the time in seconds it took the millivolt input to return to 1% of the Start mV.

 

Last Min mV:

This value is a display of the minimum millivolts measured during the last burnoff or impedance test.

 

Last Impedance:

This value is a display of the measured resistance, in Kohms, after the last impedance test.

 

Last Max TC: 

This value is a display of the maximum measured probe thermocouple input value during the last burnoff.
