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 Pro1030 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.

CARE, MAINTENANCE AND

STORAGE

This section describes the proper procedures for care, maintenance

and storage of the sensors. The goal is to maximize their lifetime and

minimize down-time associated with improper sensor usage.

GENERAL MAINTENANCE

GENERAL MAINTENANCE - GASKET AND O-RINGS

The instrument utilizes a gasket and o-rings as seals to prevent

water from entering the battery compartment and the sensor port.

Following the recommended procedures will help keep the instrument

functioning properly.

If the gasket, o-rings and sealing surfaces are not maintained properly,

it is possible that water can enter the battery compartment and/or

sensor port of the instrument. If water enters these areas, it can damage

the battery terminals or sensor port causing loss of battery power, false

readings and corrosion to the sensors or 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.

The same inspection should be made of the o-rings associated with

the ISE sensor connector when replacing the ISE sensor. The o-rings

should be free of dirt or debris before installing the sensor onto the

cable.

GENERAL MAINTENANCE - ISE SENSOR PORT

It is important that the entire sensor connector end be dry when

installing, removing or replacing the sensor. This will prevent water

from entering the port. Once the ISE sensor is removed, examine the

connector inside the port. If any moisture is present, use compressed

air to completely dry the connector or let it air dry. If the connector is

corroded, contact YSI Technical Support or the YSI authorized dealer

where you purchased the instrument.

SENSOR MAINTENANCE

SENSOR MAINTENANCE - TEMPERATURE

You must keep the temperature sensor free of build up. 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.

SENSOR MAINTENANCE - pH AND ORP

Cleaning is required whenever deposits or contaminants appear on the

glass and/or platinum sensor surfaces or when the sensor’s response

slows. The cleaning can be chemical and/or mechanical.

Removing the sensor from the cable may make cleaning easier.

Initially, use clean water and a soft clean cloth, lens cleaning tissue, or

cotton swab to remove all foreign material from the glass bulb and/

or platinum button. Then use a moistened cotton swab to carefully

remove any material that may be blocking the reference electrode

junction of the sensor.

If good pH and/or ORP response is not restored, perform the following

additional procedure:

Typical working life for pH and ORP sensors is approximately

12-24 months depending on usage, storage and

maintenance. Proper storage and maintenance generally

extends the sensor’s working life.
