Atlas ezo PH no calibration possible

Mycodo Mycodo Issue/Bug

Hello,
i have received the ph buffer solutions.
Today i wanr to calibrate the ph sensor, but an error is shown,
Can somebody point me where to look for.
This is what appears after entering teperature and then hit start calibration.

Something bad happened but it’s probably not your fault. Letting the developers know about these issues is crucial to supporting Mycodo. Please submit a new issue on GitHub with the following diagnostic information and error traceback (copy the entire traceback):

The Setup → Calibration page will soon be removed as Inputs now can contain their own calibration routines within their importable module file. Once all calibratable inputs have undergone this conversion, the Calibration page will be removed. Therefore, I am not going to be working on fixes for the Calibration page, and recommend you calibrate from the Input itself on the Input page.

Hello,
i have done the calibration in the input modul, but
I am confused about the button „ clear calibration“
Should i push it one time to clear all stored values, or is it necessary to,push it before every step of ph calibration ?

Clear calibration, then take reading of solution with ph 7.00
Push: calibrate 7.00
Can i put the sensor now in 4.00 solution or do i have to push „clear calibration“ before ?

There is a description of the calibration process written at the top of the Input. Also, Atlas Scientific’s datasheet has details of their device’s calibration procedure.

Thank you, got it now.
