: Low Pressure Set Point / Display Peak Hold
: Set Different Pressure Unit / Pressure Setting Mode
: High Pressure Set Point / Reset Peak Hold
2.0 OPERATION METHOD
1. Press and hold down the UNIT/SET button for 3 seconds. The DPG3000T will go into the pressure setting mode to set the
high or low pressure set points.
2. Press and release the button to check the value of the low pressure setting, and the low pressure set point will be displayed
for 3 seconds.
3. Press and release the button to check the value of the high pressure setting, and the high pressure set point will be displayed
for 3 seconds.
4. Press and release the button and the button at the same time for 3 seconds, the LCD will display “8888” and then
reset zero. This is in order to make sure the input port is eigher disconnected or connected to a “0” psi input.
(NOTE.: Do Not operate the step when the DPG3000T in the airtight pipeline which has pressure. And plase reset zero under
the atmospheric pressure.)
5. To set the high or low pressure set points:
(a.) Press and hold down the UNIT/SET button for 3 seconds, the screen shows on the top, left hand side indicating
high pressure setting, and the first digit will be flashing.
(b.) Set the first digit value by press the button (select from 0 to 9).
(c.) Then pressure the button, which shifts to the second digit. Again use the button to select 0 thru 9 followed
by the button to complete the third and fourth digits.
(d.) After all 4 digits of the high pressure setting are down press the button one more time, the screen will show on
the top, left hand side indicating low pressure setting. Repeat steps (b) and (c) above to set the 4 digits of the low pressure
settings.
(e.) After all 4 digits of the low pressure setting are down press the button one more time, the screen will show “LOAD”,
indicating your pressure settings have been saved into memory.
(f.) To make sure that the settings are correct, you can press the button to check the value of the low pressure setting and
press the button to check the value of the high pressure setting.
6. Display and reset peak hold:
(a.) To see the maximum peak pressure the unit has measured:
Press and hold down the button for 3 seconds. The maximum peak pressure value will be displayed and will blink on
the screen.
(b.) To reset the maximum peak pressure:
Press and hold down the button for 3 seconds, and the peak hold value will reset.
(c.) To return to the current pressure reading:
Press and hold down the button for 3 seconds and the gauge will be back to the measurement mode, the current pressure
measurement will be displayed and will not blink.

4.0 OPERATING STEPS
STEP1: Insert the wire connection with the gauge. There are 4 wires of Blue, White, Brown and Black wire,
the input voltage is 10~16 VDC.
STEP2-a: (No 4~20mA) Voltage connect with white wire ; connect with black and bule wire.
If the black and blue wire are not short circuit, the LED won’t display.
STEP2-b: (with 4~20mA) Voltage connect with white wire; connect with black wire.
Electric meter: black wire- COM ; red wire- mA+
STEP3: Zero Adjustable: Press and hold the button and for 3 seconds, until “0” has displayed. (this step must be operated
in atmospheric)
