unIt Id
Unit ID is used to identify instruments in the Data Manager software program
that was included with your instrument. It is also used to identify GLP files, Site
Lists, Configuration files, and Data files transferred from the instrument to the
PC. the default Unit ID is the instrument’s serial number. to modify the Unit
ID, highlight Unit ID, press enter and then use the alpha/numeric entry screen.
the character limit is 16 characters.

the following section is separated by parameter and will discuss sensor setup,
display options, auto stable features, and calibration procedures for each
parameter. the sections are separated by parameter due to the versatility of the
Pro Plus. You may focus solely on the parameters of your choice.
For the highest accuracy, calibrate or verify each sensor regularly. For your
convenience, YSI offers 5580 Confidence Solution® which allows you to check
the accuracy of pH, conductivity, and oRP readings to help determine if a sensor
calibration is necessary.
If you receive an error message during a calibration that indicates questionable
results, you have the option to either accept or decline the calibration. YSI
recommends that you decline a questionable calibration since accepting it may
result in erroneous data. After declining a questionable calibration, ensure the
sensor is clean, the calibration solution is good, the calibration vessel is clean,
and that you are entering the correct calibration value if entering manually.
then, try to recalibrate the sensor. If you continue to have problems, see the
troubleshooting section of this manual.
teMperature
All probe/cable assemblies, except the Quatro,
have a built-in temperature sensor. the Quatro
cable ships with a Conductivity/temperature
sensor that must be installed on the cable.
temperature calibration is not required nor is
it available.
to set the units, press Sensor , highlight
Display and press enter. Highlight Temperature
and press enter. Highlight the desired
temperature units of °F, °C, or K and press enter to confirm the selection. only
one temperature unit may be displayed at a time. You may also choose not to
display temperature. If you choose not to display temperature, other parameters
that require a temperature reading will still be temperature compensated.
dIssolVed oxyGen (do)
Do sensors can be used on 60520-X, 6051020-X, 6052030-X, and Quatro
cables.

the dissolved oxygen sensor is shipped with a dry, protective red cap that will
need to be removed before using. It is very important to put a new membrane
with electrolyte solution on the sensor after removing the red cap.
Prepare the membrane solution according to the instructions on the bottle. After
mixing, allow the solution to sit for 1 hour. this will help prevent air bubbles
from later developing under the membrane. Ensure you are using the correct
electrolyte solution for the correct sensor. Galvanic sensors utilize electrolyte
with a light blue label and Polarographic sensors utilize electrolyte with a white
label. the dissolved oxygen sensor is supplied with cap membranes specific
to the sensor type ordered (Polarographic or Galvanic). 5912, 5913, and 5914
membrane kits are for Galvanic sensors and the 5906, 5908, and 5909 membrane
kits are for Polarographic sensors. See the Setup - Dissolved Oxygen section of
this manual for more information on the different types of membranes available
from YSI.
Remove the red cap by pulling it straight off the sensor tip. Discard or save for
later use during long term storage. thoroughly rinse the sensor tip with distilled
or deionized water. Fill the cap membrane 3⁄4 full of electrolyte solution, then
tap the cap with a finger to release any trapped air. Be careful not to touch
the membrane portion of the cap. thread the membrane cap onto the sensor,
moderately tight. Do not use a tool. It’s typical for some of the electrolyte
solution to spill over. For detailed instructions on changing a membrane cap,
see the Care, Maintenance, and Storage section of this manual.
