5.6 Points

The Points menu option allows the user to program parameters directly affecting Points. The Points are the actual
channels in the Recorder and may be direct inputs, conditioned direct inputs (scaled or adjusted), computational
channels or external (serial) inputs for a total of 15.
To program Points:
From the Program menu use the UP (↑ ↑ ↑ ↑ ↑ ) or DOWN (↓ ↓ ↓ ↓ ↓ ) button to highlight Points and then
press the ENTER button. The Points menu will be displayed as shown in Figure 5-5. Use the
UP (↑ ↑ ↑ ↑ ↑ ) or DOWN (↓ ↓ ↓ ↓ ↓ ) button to select the option you wish to program and then press the
ENTER button. The options are described in the following sections.

5.6.1 Constants

The Constants menu option allows the user to program up to fifteen different constants for use in equations for
point programming. These Constants, referred to as Kx (where x = 1 to 9, A to F), are substituted into equations
instead of writing the Constant value. This simplifies programming an equation.
To program Constants:
From the Points menu use the UP (↑ ↑ ↑ ↑ ↑ ) or DOWN (↓ ↓ ↓ ↓ ↓ ) button to highlight Constants and press the ENTER button.
A keypad with the Constants 1 to 9 and A to F will be displayed. Press the desired Constant number and press
the ENTER button. Use the numeric keypad to program the desired Constant value for the selected Constant
number. Only a total of 13 characters including decimal points are available and will show on display. The
Constants are entered in decimal (0.002345) or exponential (2.345E-3) format and may be positive or negative.
When the desired value for the Constant is programmed, press the ENTER button or press the EXIT button to
cancel. Repeat for each Constant. Once all Constants are programmed, press the EXIT button to return to the
Points menu.

5.6.2 Programming Points

The Prog point menu option allows the user to setup, copy, restore, modify, or delete a point's parameters. The
programming sequence follows a general order for custom programming and the system prompts you to
submit various parameters.
To Program a Point:
From the Points menu use the UP (↑ ↑ ↑ ↑ ↑ ) or DOWN (↓ ↓ ↓ ↓ ↓ ) button to highlight Prog point and press the ENTER
button. You will be prompted with "point? x". Use the numeric keypad (1 - 9, A - F) to enter the point to be
programmed or modified and press the ENTER button. For unprogrammed points you will have three Point
programming options: Setup pt, Copy pt and Restore pt. If the point has already been setup, you will have two
Point programming options: Modify pt and Delete pt. See the following sections for more details.
NOTE: If at any point you exit the Points programming menu after having made any changes, (repeatedly
pressing exit) you will be prompted with the message "keep setup?". If you select NO at this time, any
changes you have just made will be lost. If you choose YES, the changes you made will be applied to the point.

5.6.3 Point Programming Options

After a point number is chosen, if the point is a new point to program, the point can be setup from scratch,
copied from another point already setup, or restored if the point had been setup previously and then deleted. If
the point chosen has already been setup, the point parameters may be modified or the point may be deleted.

5.6.3.1 Setup an Unprogrammed Point (Setup pt)

After selecting which point to program, use the UP (↑ ↑ ↑ ↑ ↑ ) or DOWN (↓ ↓ ↓ ↓ ↓ ) button to highlight Setup pt and press
the ENTER button. The first step in programming a point is to set the Point Type (see Section 5.6.4).
