4 Maintenance Menu<br />
What you can do in the Maintenance<br />
menu<br />
The Maintenance menu provides all functions for<br />
sensor maintenance and adjustment of connected<br />
units.<br />
Access to the Maintenance menu can be protected<br />
by a passcode.<br />
<br />

<br />
Measurement point maintenance allows to dismount<br />
the cell.<br />
The probe rinsing function (option 352) permits<br />
automatic rinsing and cleaning of the cell: see<br />
page 9–44.<br />
Resistance measurement permits direct display<br />
of the ohmic resistance at the measuring input.<br />
The current source allows to manually adjust<br />
the output currents (1 and 2) for adjusting and<br />
checking connected peripheral devices (such<br />
as indicator or recorder).<br />
Temperature probe adjustment allows individual<br />
calibration of the temperature probe to increase<br />
accuracy of conductivity measurement (only<br />
effective with process medium TC enabled).<br />
If the unit is equipped with a controller function<br />
(option 353), controller output Y (manipulated<br />
variable) can be entered manually.<br />
Only with option 352: In the ”Measurement Point<br />
Maintenance” submenu, the ”probe” contact is active.<br />
A timer controlled rinsing cycle will not be<br />
started (see page 9–44).<br />
