4.3PROGRAMMING AND CALIBRATING THE SOLU COMP II - TUTORIAL

Setting up and calibrating the Solu Comp II is easy. The following tutorial describes how to move around in the programming menus. For practice, the tutorial also describes how to assign conductivity values to the 4 and 20 mA outputs for sensor 1.

1.If the MENU screen (shown at the left) is not already showing, press MENU. Calibrate is blinking, which means the cursor is on Calibrate.

2.To assign pH or conductivity values to current outputs, the Program sub-

menu must be open. Press . The cursor moves to Program (Program blinking). Press ENTER. Pressing ENTER opens the Program sub-menu.

3.The Program sub-menu permits the user to set outputs, alarms, auto- matic or manual temperature compensation, and a security code. When the sub-menu opens, Outputs is blinking, which means the cursor is on

Outputs. Press or (or any arrow key) to move the cursor around the display. Move the cursor to >> and press ENTER to cause a second screen with more program items to appear. There are three screens in the Program menu. Pressing >> and ENTER in the third screen causes the display to return to the first screen (Outputs, Alarms, Measurement).

4.For practice, assign pH values to the 4 and 20 mA outputs for sensor 1. Move the cursor to Outputs and press ENTER.

5.The screen shown at left appears. The cursor is on Output Range (blink- ing). Output range is used to assign values to the low and high current out- puts. Press ENTER.

6.The screen shown at left appears. The Solu Comp II has two outputs, out- put 1 and output 2. Move the cursor to the desired output and press ENTER. For purposes of the example, choose Output 1.

7.The screen shown at left appears. Out1 S1 in the top line means output 1 (Out1) is assigned to sensor 1 (S1). Either output can be assigned to either sensor (sensor and output assignments are made under the Output Configure menu shown in step 5). Use the Out1 S1 Range? screen to assign a pH value to the 4 mA output.

a.	Use the arrow keys to change the pH to the desired value. Press			or
	to move the cursor from digit to digit. Press		or to increase or
	decrease the value of the digit. Holding	or	down causes the
	numeral to continuously scroll up or down.
b.	To move the decimal point, press or until the cursor is on the dec-
	imal point. Press to move the decimal point to the right. Press			to
	move the decimal point to the left.

c. Press ENTER to store the setting.

8.The screen shown at left appears. Use this screen to assign a full scale pH value to the 20 mA output. Use the arrow keys to change the pH to the desired value. Press ENTER to store the setting.

9.The screen shown at left appears. To assign values to the low and high currents for output 2, select Output 2 and follow the prompts.

10.To return to the main menu, press MENU. To return to the main display press MENU then EXIT, or press EXIT repeatedly until the main display appears. To return to the previous display press EXIT.

NOTE

To store values or settings, press ENTER before pressing EXIT.
