Figure 4.5
Notes:
- Insert port plugs into unused sensor port(s) - figure 4.5.
- The sensor must be enabled to calibrate.
- If you use another container for calibration be sure to handle the sensors
will care to protect them from possible physical damage. (See YSI 5562
probe sensor guard - figure 3.12 on page 36 or YSI 5561 probe sensor
guard - figure 3.11 on page 35.) Use a ring stand and clamp to secure
the probe assembly.
- Older sensors may take longer to calibrate than new ones because the sensor
readings may take longer to stabilize.

Calibration Log
Calibration data is stored in the 5200A calibration log. A calibration data record
includes the type of sensor calibrated, the date and time of the calibration and the
calibration method. Press
at the Run Screen to view the calibration log
- page 168.
Notes:
- Use AquaManager to view and save calibration data on a PC. In addition
to the calibration log information listed above, AquaManager calibration
logs also include user inputs 1 and 2 and the pre and post calibration slopes/
offsets of the sensor(s) when applicable.
- Information from cancelled calibrations is not stored.
Conductivity
Menus → Calibration→ Conductivity
See figure 4.5 to determine which sensor is the conductivity sensor. The conductivity
sensor calibration is a one-point calibration. Calibrate using a traceable conductiv-
ity solution that has a value close to the conductivity value of the water system to
be monitored.
Directions to Calibrate Conductivity Sensor
1. Connect probe/cable assembly - page 61.
2. Read Getting Ready to Calibrate - page 75.
3. Fill calibration/storage cup with 55 ml of traceable conductivity calibration
solution that has a known value.
4. Carefully immerse the sensors into solution. Ensure that the top vent
hole of the conductivity sensor is fully immersed in the solution - figure
4.5, page 76.
5. Gently move the probe module up and down to remove any air bubbles
trapped in the conductivity sensor vent hole.
6. Screw the calibration/storage cup onto the threads of the probe module.
7. Enter conductivity calibration menu:
Menus → Calibration→ Conductivity
8. Allow at least one minute for the temperature to equilibrate.
