SENSOR STORAGE
It is best to calibrate just before field use. However, should you need
to store calibrated sensors, there are a couple of options:
s
stalled. Remove the Cal Cup and rinse it and the sensors. Moisten
a sponge and place it in the bottom, or add a little water (deionized,
distilled, or tap) to the Cal Cup—just enough to create a moist
environment. Return the probe to the Cal Cup for transport to the
field site.
TIP: Deionized water is preferred over tap water, but it is not
essential; especially if the local tap water is of good quality.
To seal the Cal Cup against leakage, seat it lightly against
the o-ring on the instrument body. It is best not to over-
tighten.
s
Store the conductivity sensor dry. Store the DO, pH, and pH/ORP
sensors in their storage bottles (located in the sensor kits): DO in
clean water, pH and pH/ORP in the solution they were shipped in,
or with a moist sponge in the sensor storage bottle to avoid deplet-
ing the reference solution.
CALIBRATION HISTORY
Each time a sensor is calibrated, the information is written to the
sensor, where it is stored until the next calibration. Details on the most
recent calibration are displayed by the software when a parameter is
selected in the Navigation tree.
The software also creates a calibration report in html format each time
a sensor is calibrated. A separate report is created for every calibra-
tion of every parameter—even for a calibration that was cancelled.
You have the option to view the report immediately after calibration.
Reports are stored for later retrieval and reference in a folder named
“Calibration Reports” in the folder where Win-Situ 4 or Pocket-Situ
4 is installed. Reports include a detailed record of date and time,
parameter, calibration type, number of calibration points, stimulus and
response, and calculated coefficients. An index in html format is also
created and updated each time a calibration is performed.
