Using a Custom Probe
• To recall the specifications of a Vernier sensor and configure custom
probe settings
1. Perform the first two steps of the procedure under “To configure a custom probe setup”
on page
ε
-19.
2. Press
5(VERNIR).
• This displays a Vernier sensor list.
3. Use the
f and c keys to move the highlighting to the Vernier sensor whose setting
you want to use as the basis of the custom probe settings, and then press
w.
• The name and specifications of the Vernier sensor you select will appear on the custom
probe setup screen.
• To complete this procedure, perform steps 4 through 7 under “To configure a custom
probe setup” (page
ε
-19).
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 EA-200, and connect the custom probe you want to auto
calibrate to CH1 of the EA-200.
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
ε
-19.
• 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:
(1) On the Custom Probe List, use the
f and c cursor keys to highlight the name of
the custom probe you want to edit, and then press
3(EDIT).
(2) Perform the procedure starting from step 6 under “To configure a custom probe setup”
on page
ε
