k Auto Calibrating a Custom Probe

Auto calibration automatically corrects the slope and intercept values of a custom probe

setup based on two actual samples.

Important!

• Before performing the procedure below, you should prepare two conditions whose

measurement values are known.

• When inputting reference value in step 5 of the procedure below, input the exact known

measurement value of the condition you will sample in step 4. When inputting reference

value in step 7 of the procedure below, input the exact known measurement value of the

condition you will sample in step 6.

To auto calibrate a custom probe

1. Connect the calculator and Data Logger, and connect the custom probe you want to auto

calibrate to CH1 of the Data Logger.

2. What you should do first depends on whether you are configuring a new custom probe for

calibration, or editing the configuration of an existing custom probe.

If you are configuring a new custom probe:

• Perform steps 1 through 6 of the procedure under “To configure a custom probe setup”

on page 4-1.

• Auto calibrate will automatically set the slope and intercept, so you do not need to

specify them in step 6 of the above procedure.

If you are editing the configuration of an existing custom probe:

• Perform steps 1 through 3 of the procedure under “To edit a custom probe setup” on

page 4-6.

3. Press 2(CALIB).

• This will start the first sampling operation with the sensor connected to Data Logger’s

CH1, and then display a screen like the one shown below.
