Need Programming Help 512-DC-RC

[amust]

I recently purchase the EASY 512-DC-RC and the Easy-soft  5.11 .
I am new to Relay Controller, and have almost no experience with it.
My goal is to use it to measure the time travelled between 2 points.
The Easy 500-700 control relay manual  shows a potentiometer input capability.

The potentiometer that I am using has a 30mm travel.

So basically , I want to pick 2 point within the 30mm, say at 10mm and 20mm.
As the Moeller detected the voltage at the 10mm position it will start the clock and at 20mm stop the clock, ( or vice versa).
The voltage difference is provided by the potentiometer (as an input to the  512-DC-RC).

The potentiometer and the 512-DC-RC are the only 2 components that I am using in the setup.
In other words I do not use the MFD or other external display.
I check and Moeller support said that I can get the time to show in the  512-DC-RC LCD display.

My questions is that:
How do I program the 512-DC-RC to do this. Better yet , can someone provide me with this program?
