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 -
with care, especially the pH sensor, in order to protect the sensors 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 159.
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
Connect probe/cable assembly - 1. page 60.
Read 2. Getting Ready to Calibrate - page 73.
Fill calibration/storage cup with 3. 55 ml of traceable conductivity calibration
solution that has a known value.
Carefully immerse the sensors into solution. Ensure that the top vent 4.
hole of the conductivity sensor is fully immersed in the solution - figure
4.5, page 74.
Gently move the probe module up and down to remove any air bubbles 5.
trapped in the conductivity sensor.
Screw the calibration/storage cup onto the threads of the probe module. 6.
Enter conductivity calibration menu: 7.
Menus → Calibration→ Conductivity
Allow at least one minute for the temperature to equilibrate. 8.
