Maintenance/Calibration Reminders
The PHD Ultra monitors usage and provides convenient reminders for periodic maintenance or calibration.
You can adjust the settings for the reminders to accommodate your specific operating conditions.
H
arvard Apparatus recommends that system calibration checks/adjustments be performed at least once per
year on the pump and that lubrication should be performed once every 200 hours of operation.

TO ADJUST THE MAINTENANCE/CALIBRATION REMINDERS:

reminder of when calibration is suggested. Note that the next date for suggested calibration is
displayed on this screen at all times.

Lubrication timer. To reset the time, choose the Reset button in the Lubrication section of the
