9.3 TEST AND VERIFICATION PROCEDURE

Connect the YSI Model 3200 as shown in the Test and Verification Figure and follow the charts
below to verify its accuracy.

Equipment Required:

If using the YSI 3166 Precision Calibrator Set to simulate conductance, a YSI 3232 adapter is
required for proper connection to the cell connector. When using the 3232 adapter, temperature
can only be accessed via the EXT. TEMP connector which requires a .25” three conductor phone
plug.

If a decade resistance box is used to simulate conductance and temperature, a YSI #003229 cable
is required for connection to the cell connector.

Important Notes:

1. Temperature compensation must be turned off.

2. Put the 3200 in manual range mode.

3. Set the units to conductance and/or resistance.

4. The 3200 has no internal calibration. Opening the case should only be attempted by a

qualified service technician or permanent damage may result.
