However, for applications where the pH during wash shows almost the same value as the normal
pH, the difference will be approximately zero. In such a case, disable the wash recovery check.
An example of such applications is the monitoring of waste water pH. If you select water jet
cleaning in such a case, the normal pH as well as the washing time pH will be around pH 7; the
difference will be approximately zero, so the recovery time check will not work normally.
This function is available either for ORP measurement only.
