Setpoint : 1.000 ppm

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

3.Press Enter (F4).

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

5.The screen appearing at this point depends on how the alarm was configured.

6.If the alarm is a normal (i.e., not TPC) alarm, a screen like the one shown will appear. The alarm is a low alarm and the setpoint is 0.00 ppm. 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 a new alarm.

7.If the alarm is TPC, a screen like the one shown will appear. The set- point is +1.000 ppm. 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 a new alarm.
