ε-20 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-19. 20100801
