Delta DPA Series Instruction Sheet

Series Pressure Sensor
Instruction Sheet
Thank you very much for choosing Delta DPA series pressure sensor. Please read this instruction sheet carefully before
using your DPA. Keep this instruction sheet handy for quick reference.
Warning
DANGER! CAUTION! ELECTRIC SHOCK!
DPA is a pressure measurement device. DO NOT use it out of its specification. Improper pressure or
incorrect wiring may cause series injuries on staff or damages on other devices.
1. Keep away from high-voltage and high-frequency environment during the installation in case of interference.
Prevent using the device in premises which contain:
(a) dust or corrosive gas; (b) high humidity and high radiation; (c) shock and vibration.
2. DPA can only be used for air pressure measurement and should avoid corrosive, inflammable or toxic gas
measurement.
3. Make sure the power supply is switched off when installing or dismounting DPA and the pressure source stops its
action in case harms occur on human body and properties.
4. DO use parts compatible to the specification of the pressure pore for connection to avoid mistaken measurement or
safety problems.
5. Before switching on the power supply, check the signal connection, e.g. the input voltage and polarity. Voltage that is
too high may cause damages on DPA.
6. DO use dry cloth and DO NOT use acid or alkaline liquid to clean the device.

How to Set up Parameters
Switching modes: DPA will be in the "Measuring Mode" when it is switched on, displaying PV and SV. Press
more than 2 seconds in this mode to switch to the "Quick Setup Mode". Press
"measuring mode" to switch to "Advanced Setup Mode". Press in the "Quick Setup Mode" or "Advanced Setup
Mode" to return to the "Measuring Mode".
Setting up parameters: In the three modes, press once to select the parameter to set up. When you find the
parameter to be set up or modify, use to modify the setting.
