operation
1) Manual Pushbutton Auto Zero
NOTE: Supply voltage must be connected at least one hour prior to zero point adjustment.
a) Disconnect both pressure tubes from the pressure ports l and –, and install short tube conn to - ...
(see Figure 5).
b) Push down the zero button (see Figure 7) until the LED light (red) turns on and the display reads “zeroing”
c) The zeroing of the device will proceed automatically. Zeroing is complete when the LED turns off, and
the display reads 0. Press zero button again if zero is not displayed.
d) Reinstall the pressure tubes, ensuring the High pressure tube is connected to the port l, and
the Low pressure tube is connected to the port labeled. (see Figure 5)
NOTE: The zero point should be calibrated via manual auto zero, one hour after installation and at least every 12
months during normal operations.
1) The device requires 24VDC/VAC power at terminals 24V & GND.
2) With no air flowing through the AMS and power applied to the controller, the DPT-IQ will generate a Vout 0V or
0mA signal between Vout and GND.
