3. You will be presented with a character keypad and asked for the
lo
w scale end value. Assume that you

the resolution that you can see. Use the character keypad buttons to enter a
lo
w value of
40
and then
press the
ENTER
button.
4. You will then be asked for a
mid
-scale value. To keep things linear, use the character keypad buttons to
enter a
mid
point value of
60
, which is halfway between the 40 and 80 end points chosen to select, then
press the
ENTER
button.
5. You will then be asked for the

You have just programmed Point 1 to be a live input of 0 - 1 volts which will be scaled to an output of 0 - 100% and
you have chosen to display between 40 and 80% full scale on the display, and this is what will be recorded to disk/
card. You can now program the other points in a similar fashion. It is suggested that you fully read the rest of the
chapters of this manual to become familiar with the functions of the various menu options.
