The cell constant for a conductivity sensor may be entered “by hand,”
without performing a complete calibration, if desired. See the proce-
dure in Section 12 below.
TIP: When using Pocket-Situ to perform calibrations, do not
let the PDA time out during the procedure. To locate this
setting in most PDAs, display the Start menu, select
Settings, System tab, Power.
PREPARING TO CALIBRATE
CALIBRATION KITS
Kits of calibration solutions for various parameters and ranges are
available from In-Situ Inc. Our calibration solutions are certified to
N.I.S.T. standards, packaged in quarts, each providing sufficient
mUID
The Quick Cal kit provides a convenient “universal” calibration solu-
tion, designed to calibrate multiple parameters simultaneously.
THE CALIBRATION CUP
The clear acrylic Cal Cup shipped with your MP TROLL 9500 is
used to hold solution during sensor calibration. When fitted with a
small moist sponge, it also provides a convenient way to protect and
hydrate the sensors of the MP TROLL 9500 between uses.
The base of the Cal Cup is removable so that the stirrer may be
attached for calibrations where continuous agitation of the solution is
recommended. A small hole in the threads of the base near the o-ring
permits venting during 100% dissolved oxygen calibration with the Cal
Cup and probe inverted.
The Cal Cup’s fill lines indicate the recommended amount of
solution for most calibrations, and ensures the temperature
sensor is immersed.

When attaching the Cal Cup to the front end of the MP TROLL 9500,
align carefully and thread the Cal Cup onto the body until seated
against the o-ring, then back off slightly to avoid overtightening.
When attaching the Cal Cup to the instrument body, be
careful not to overtighten.
