CHLORIDE CALIBRATION PROCEDURE
1. Rinse the Cal Cup and front end of the MP TROLL 9500 in clean
water. Rinse very thoroughly if the chloride sensor has recently
been exposed to pH buffers during a pH calibration. Shake to dry.
For best results, follow this with a rinse in a portion of the selected
calibration solution. Discard the rinse solution.
2. Insure the black PVC base (or the stirrer) is attached to the Cal
Cup, and fill the Cal Cup to the fill line with the selected calibration
solution.

3. Insert the front end of the MP TROLL 9500
into the open end of the Cal Cup. Thread the
Cal Cup onto the body until seated against the
o-ring, then back off slightly to avoid overtight-
ening.
To stabilize the instrument, you may wish to
use a calibration stand or other support.
4. Connect the MP TROLL 9500 to a PC and
establish a connection in Win-Situ 4 or Pocket-
Situ 4. Win-Situ screens are illustrated here.
The Pocket-Situ interface is similar, with the
Navigation tree at the top of the screen and
the Information pane below it.
5. Select the MP TROLL 9500 in the Navigation
tree.
The software will automatically detect and display the installed sen-
sors. If one or more sensors is installed in the wrong port, an error
message will be displayed. Simply remove the sensor and install it
in the correct position, then “refresh” the device before continuing.
6. Select Chloride in the Parameters list. The sensor serial number
(S/N) and recent calibration information is displayed.
7. Select Calibrate.
The Chloride Calibration Wizard starts. A screen like this is dis-
played.
8. Select the number of calibration points for this calibration, and the
concentration (ppm) of the calibration solution for each point.
Cal point 1 is the solution the sensor is soaking in now, the lowest
concentration for a multi-point calibration. If doing a three-point
bithermal cal, choose cal point 3 to be the same as either cal point
1 or cal point 2.
9. Select Next to continue.
