5.2 RANGING THE OUTPUTS

1.Ranging the outputs means assigning values to the low (0 or 4 mA) and high (20 mA) outputs. Before rang- ing the outputs, be sure the outputs are properly configured. See Section 5.5.

2.Press any key to enter the main menu. Move the cursor to "Program" and press Enter (F4).

3.Move the cursor to "Output setpoints" and press Enter (F4).

ExitEnter

Output 1 setpoints Output 2 setpoints

4. Move the cursor to the desired output and press Enter (F4).

ExitEnter

CAUTION: Current Output 1 will be affected.

5.This screen confirms that changes to output 1 are going to be made. Press Cont (F3) to continue. Otherwise, press Abort (F1).

Abort Cont

4 mA : 0.00 ppm

20 mA: 20.00 ppm

Output 1: 12.00 mA

ExitEdit

6.This screen shows the present settings for Output 1. If the output was configured to be 0-20 mA, the first line will show "0mA" instead of "4mA". The live current output is shown on the third line.

Move the cursor to the desired line and press Edit (F4). Use the arrow keys to change the setpoint. Press Save (F4) to store the new value.

Press Exit (F1) to return to the screen in step 4. Choose the other output and continue.
