How to Recalibrate a Nomiku Classic

***Calibration instructions start below***

Before attempting calibration, reset your Nomiku to its Factory settings. To do this:
-Hold the screen of Nomiku while you plug the cord into the wall.
-Wait for the screen to show "Turn ->" 
-Turn the knob clockwise until the Nomiku shows "PASS"
-Tap the screen once while “>” is next to “Calibration”
-In the calibration screen, with “New temp:” displayed, tap the screen so the line is replaced with “RESET ALL”
-Hold the screen for 5 seconds until “reset calibration.” appears 
-Nomiku is now at factory setting 
-Unplug Nomiku and proceed to calibration
Now that you have reset your Nomiku, here is how to calibrate:
For two point calibration: (use this method  if the temperature display is far off the actual temperature)
It's important that the calibration happens from low to high. The lower set point (50ºC) is set first, then calibrated to the higher one at (85ºC) after. The Nomiku will not be calibrated correctly if it is calibrated in reverse from high to low. It will help if you have a second circulator to help regulate the calibration bath,
-Put Nomiku in a water bath at a reference temperature 50 degrees C and holding. Check by using a quality reference thermometer.
-Hold the screen of Nomiku while you plug the cord into the wall.
-Wait for the screen to show "Turn ->" 
-Turn the knob clockwise until the Nomiku shows "PASS" or “Err: 512”. “Err:512” will be cleared after two point calibration.
-Tap the screen once.
-With the ">" symbol next to "Calibration", tap the screen once again. To move the ">" symbol up and down, you may turn the knob. If you accidentally enter another mode, you will need to unplug Nomiku and start again.
-Nomiku will now show "Temp:" and "New temp:". "Temp:" shows what temperature Nomiku thinks the water is. If the screen displays “RESET ALL”, tap the screen so that it displays the line with “New temp:”
-Use a quality reference thermometer to test the true temperature of the water.  
-Turn the knob until "New Temp" matches your reference temperature of the thermometer.
-With "New temp:" showing the correct temperature, press and hold the screen for 5 seconds. Nomiku will display "Set temp:" and your temperature.
-Confirm that the "Temp:" matches your reference temperature after a few seconds. If not, repeat the last two steps.
-You can unplug Nomiku and prepare for the next step.
-Put Nomiku in a water bath at a reference temperature 85 degrees C and holding.
-Use a quality reference thermometer to test the true temperature of the water.  
-Turn the knob until "New Temp" matches your reference temperature.
-With "New temp:" showing the correct temperature, press and hold the screen for 5 seconds. Nomiku will display "Set temp:" and your temperature.
-Confirm that the "Temp:" matches your reference temperature after a few seconds. If not, repeat the last two steps.
-Unplug Nomiku to complete the calibration process
To check the accuracy of the Nomiku
-Set water bath at 70 degrees C. 
-Place Nomiku in bath & turn on. Make sure that the temperature on the Nomiku is set to 0 degrees C so there is no extra heating.
-Test temperature of water with thermometer and see them match
-The Nomiku should be within 0.3 degrees C to be considered calibrated.
