u To zero adjust 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.
(1) Connect the EA-200 to your ClassPad, and connect the custom probe you want to zero
adjust to the EA-200’s CH1 channel.
(2) What you should do next depends on whether you are calibrating a new custom probe
or an existing custom probe whose settings have been edited.
When calibrating a new custom probe:
• Perform steps (1) through (5) under “To configure a new custom probe” on page 3-12.
• You can skip step (2), if you want.
When calibrating an existing custom probe:
• Perform steps (1) through (6) under “To edit an existing custom probe” on page 3-14.
(3) Tap [Zero Adjust].
• This starts sampling by the sensor connected to the
CH1 channel and displays a Sampling... dialog box
like the one shown to the right. This is how the dialog
box appears during standby prior to the sample.
• If this dialog box is left on the display, sampling will
terminate and the dialog box will close automatically
after about five hours.
(4) Tap [Set] when you are ready to take the sample.
• This closes the Sampling... dialog box and returns to the Custom Probe dialog box.
• The value produced by the sample is entered automatically for [Intercept].
(5) After you are finished, tap [Set] to save the custom probe and close the Custom Probe
dialog box.
Tip
• An error occurs if the sample value in step (4) is not correct. If this happens, repeat the procedure
from step (3).
