kZero Adjusting a Custom Probe

This procedure zero adjusts a custom probe and sets its intercept value based on an actual sample using the applicable custom probe.

u To zero adjust a custom probe

1.Connect the calculator and EA-200, and connect the custom probe you want to zero adjust to CH1 of the EA-200.

2.What you should do first depends on whether you are configuring a new custom probe for zero adjusting, 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 intercept, so you do not need to specify it 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 3(ZERO).

•This will start the sampling operation with the sensor connected to EA-200’s CH1, and then display a screen like the one shown below.
