Figure 10, Erase data mode.
Use the up or down arrow key to select Erase Data Set, Erase All Sets or the ESC-
Exit function box, then press enter to confirm.
Select ESC-Exit and press enter to exit Erase mode without erasing any data.
Select Erase Data Set and press enter to erase the data set that was displayed
before entering Erase mode. For example, if data set 12 was displayed before
entering erase mode, and Erase Data Set is selected, Data Set 12 will be erased
from memory and the data sets AFTER that number will move up to keep them
sequential. For example, if there are15 records and number 12 is erased then 13
becomes 12, 14 becomes 13, and 15 becomes 14. The instrument will return to
Data mode after erasing one data set.
Select Erase All Data Sets and press enter to clear the Pro30 memory and return
to Data mode.
EXITING DATA MoDE
While in Data mode, press enter to access the bottom functions. Next, highlight
the ESC-Exit box and press enter to return to the Run screen.

This section describes the proper procedures for care, maintenance and storage
of the instrument. The goal is to maximize their lifetime and minimize down-
time associated with improper instrument usage.

GENERAL MAINTENANCE - GASKET
The instrument utilizes a gasket as a seal to prevent water from entering the
battery compartment. Following the recommended procedures will help keep
the instrument functioning properly.
If the gasket and sealing surfaces are not maintained properly, it is possible that
water can enter the battery compartment. If water enters this area, it can severely
damage the battery terminals causing loss of battery power and corrosion to the
battery terminals. Therefore, when the battery compartment lid is removed, the
gasket that provides the seal should be carefully inspected for contamination (i.e.
debris, grit, etc.) and cleaned with water and mild detergent if necessary.

SENSoR MAINTENANCE - TEMPERATURE
You must keep the temperature sensor free of build up. other than that, no
additional maintenance is required. A toothbrush can be used to scrub the
temperature sensor if needed.
SENSoR MAINTENANCE - CoNDUCTIVITY
The openings that allow sample access to the conductivity electrodes should be
cleaned regularly. The small cleaning brush included in the Maintenance Kit is
intended for this purpose. Dip the brush in clean water and insert it into each
hole 10 to 12 times. In the event that deposits have formed on the electrodes, it
may be necessary to use a mild detergent (laboratory grade soap or bathroom
foaming tile cleaner) with the brush. Rinse thoroughly with clean water, then
check the response and accuracy of the conductivity cell with a calibration
solution.
