Analog Output - Delta DPA Series Instruction Sheet

2. Hysteresis Mode: Set up pressure Hi/Lo. When the pressure measured is bigger than the Hi value, the output will be ON. When the
pressure measured is smaller than the Lo value, the output will be OFF. (See Figure 2: Output in Hysteresis Mode)
 In the "Measuring Mode", press
Lo). Use to set up Hi/Lo values.
3. Window Mode: Set up pressure Hi/Lo. When the pressure measured is bigger than Hi or smaller than Lo, the output will be OFF. When the
pressure measured is bigger than Lo and smaller than Hi, the output will be ON. (See Figure 3: Output in Window Mode)
 In the "Measuring Mode", press
Lo). Use to set up Hi/Lo values.
 In the "Advanced Setup Mode", press

Note: Supposed the output is ON and the output status is set to N.O. (normally open), the output will then be off. If the output status is set
to N.C (normally closed), the output will then be on. Supposed the output is OFF and the output status is set to N.O., the output will then be on.
If the output status is set to N.C., the output will then be off.

 Analog Output
1. Full range mode:
When the input pressure starts to change, the analog output will change with the input. For example, supposed the range for input is -100kPa
~ 100kPa, and DPA reads -100kPa, the output will be 4mA or 1V. When DPA reads 100kPa, the output will be 20mA or 5V.
(See Figure 4: Full range analog Output)
2. Change analog slop mode:
When the DPA reads
