Figure 4.5

Notes:

Insert - port plugs into unused sensor port(s) - gure 4.5.

e 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 - gure 3.12

on page 36 or YSI 5561 probe sensor guard - gure 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/

osets of the sensor(s) when applicable.

Information from cancelled calibrations is not stored.

Conductivity

Menus → Calibration→ Conductivity

See gure 4.5 to determine which sensor is the conductivity sensor. e 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

hole of the conductivity sensor is fully immersed in the solution - gure

4.5, page 74.

Gently move the probe module up and down to remove any air bubbles

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.
