3. System Configuration and Operation
3.1 Turning the Instrument On
Plug the power supply into its mating connector on the back of the instrument. Depress
the (on/off) key to turn the instrument on. The instrument will activate all segments of the
display for a few seconds, which will be followed by a self test procedure which will last for
several more seconds. During this power on self test sequence, the instrument’s microprocessor
is verifying that the instrument is working properly. The Model 3100 will display the current cell
constant when the self test is complete.

CEL
If the instrument detected a problem, the display will show a continuous error message. For a list
of these error messages, see chapter 6 Troubleshooting. After the instrument completes this
diagnostic routine, the following screen should be displayed (with no cell connected).

3.2 Connect the Cell
Plug the cell (YSI 3200 series) into the connector on the back of the instrument marked cell. YSI
3200 series cells contain an internal temperature sensor for temperature measurement and
compensation.
If you are using a YSI 3400 series cell, you will need the YSI 3232 cell adapter. YSI 3400 series
cells do not contain an internal temperature sensor, therefore, when using a 3400 series cell,
temperature measurement, temperature compensation or salinity measurement is not
possible.
