The procedure below can be used to calibrate the display on the L91 high limit to match the temperature measured inside the oven.
1. See link below for the Configuration video for the L91 Hi Limit.
2. Go to the SHif parameter as described in the video
3. Adjust the SHif parameter until display on the L91 matches the temperature measured inside the oven
Example: If the display on the L91 reads 200 and the measured temperature in the oven chamber is 195, you should enter a -5 for the SHif parameter.
