Using a Custom Probe
7. Press w and then input a memory number (1 to 99).
• This saves the custom probe setup and returns to the Custom Probe List, which should
now contain the new custom probe setup you configured.
• To recall the specifications of a Vernier or CMA 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 4(VERNIR) or 5(CMA).
• This displays a sensor list.
3. Use the f and c keys to move the highlighting to the 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 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 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
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 2(EDIT).
(2) Perform the procedure starting from step 6 under “To configure a custom probe setup”
on page
ε-19.
