k Configuring a Custom Probe Setup
To configure a custom probe setup, you must input values for the constants of the fixed linear interpolation formula (ax + b). The required constants are slope (a) and intercept (b). x in the above expression (ax + b) is the sampled voltage value (sampling range: 0 to 5 volts). u To configure a custom probe setup 1. From the E-CON2 main menu (page 1-1), press 1(SET) and then c(ADV) to display the Advanced Setup menu. See 3 Using Advanced Setup for more information. 2. On the Advanced Setup menu (page 3-1), press f(Custom Probe) to display the Custom Probe List.
The message No Custom Probe appears if the Custom Probe List is empty. 3. Press 2(NEW). This displays a custom probe setup screen like the one shown below.
The initial default setting for the probe name is Voltage(6pin). The first step for configuring custom probe settings is to change this name to another one. If you want to leave the default name the way it is, skip steps 4 and 5. 4. Press 1(EDIT). This enters the probe name editing mode. 5. Input up to 18 characters for the custom probe name, and then press E. This will cause the highlighting to move to Slope.

6. Use the function keys described below to configure the custom probe setup. To change the setting of an item, first use the f and c cursor keys to move the highlighting to the item. Next, use the function keys to select the setting you want. (1) Slope Press 1(EDIT) to input the slope for the linear interpolation formula. (2) Intercept Press 1(EDIT) to input the intercept for the linear interpolation formula. (3) Unit Name Press 1(EDIT) to input up to eight characters for the unit name. (4) Warm-up Press 1(EDIT) to input the warm-up time. 7. Press wand 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. u 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 4-1. 2. Press 5(VRNR). 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 4-1).

4-3 Using a Custom Probe

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. u 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 4-1. 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:
Perform steps 1 through 3 of the procedure under To edit a custom probe setup on page 4-6. 3. Press 2(CALIB). This will start the first sampling operation with the sensor connected to EA-200s CH1, and then display a screen like the one shown below.
First sampling operation Real-time display of sampled values

4. After the sampled value stabilizes, hold down w for a few seconds. This will register the first sampled value and display it on the screen. At this time the cursor will appear at the bottom of the display, ready for input of a reference value.
