Calibration
While the oven arrives pre-calibrated from the factory, certain adjustments may be necessary for optimal
performance. Please note these adjustments will affect your oven settings! We recommend writing down
any factory settings prior to adjustment so they may be reset in the event of undesirable operation.
Probe Calibration
Follow the instructions below to adjust the temperature readout. These steps are only necessary in the
event there is a discrepancy between the display and measurements taken with an alternate device.
For example: a thermometer placed inside the oven with a different measurement than the controller.
Please note: laser probe measurements will be inaccurate without compensating for emissivity. Refer to
your laser probe’s user manual.
