DPTM Mini Differential Pressure Transmitter-Operation Manual Edition: A/1
1
DPTM Mini Differential Pressure Transmitter
Note:
For zero center models, add “Z” at the end of the model. For example, DPTR*1*Z, means the range is -30-0-30.Only 1~6 have this selection.

For zero center models, add “Z” at the end of the model. For example, DPTM*1**Z,
means the range is -30-0-30.Only 1~6 have this selection.
Connection
Different models have different electrical terminals. Please wire specific model according to the wiring diagram on the front
cover.
Setting
1. The zero-reset
button is for resetting zero drift. Press and hold the button for 5 seconds to complete the operation.
2. The RS485 terminating resistor (120Ω) is selected by the toggle switch. When “J8” is ON, the resistor (120Ω) is applied.
3. Response Time select: switch the S2 to different positions for 0.5s,1s, 2s and 5s according to the diagram below.
Note: since the time is not fully synchronized, the actual response time is 1~2 times set time.
