4 Using a Custom Probe

You can use the procedures in this section to configure a custom probe for use with a Data

Logger.

Important!

• The sensors (CASIO, Vernier, CMA) that appear on the list during Channel Setup (page

3-3) are E-CON3 mode standard sensors. If you want to use a sensor that is not included in

the list, configure custom probe settings.

• A sensor with an output voltage in the range of 0 to 5 volts can be configured with E-CON3

as a custom probe. Use of sensors with an output voltage outside of this range is not

supported.

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).

To configure a custom probe setup

1. From the E-CON3 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 1(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.
