KT-4 reads temperature range: 0C-1350C, (32F-2462F) CAN Bus and digital outputs.
Analog 0-5V outputs:
V= 5/1024 x Temperature (C)

Optional Zeitronix KLCD display

All 4 temperature readings are in Celsius and set default as EGT1, EGT2, EGT3, EGT4. Minimum EGT temperature reading is 100C, maximum 1350C.

To change units to Fahrenheit, hold side button at start up. “C” can be changed to “F”.

Next menu allows to rename “EGT” and drops minimum temperature reading to 0C. To restore KLCD to default settings hold side button at start up.
