periodic servicing and maintenance. For more information
on this, please refer to the manual(s) delivered with the
sensor(s).
This is a diagnostic tool for Hach Ultra technicians. This
feature will allow checking the ability of the EC
measurement board to measure a null current. This ability
is very important to measure traces of gas.
Press start to measure the current generated at the
sensor.
- The measurement board opens a contact in order to
measure a null current instead of the sensor current.
- The window displays the current measured, and
information as to whether the value is acceptable or
not.
If test fails please contact your Hach Ultra representative.
