Low Pressure Pneumatic Test Pump
Instructions
Introduction
The 730LTP40k Low Pressure Pneumatic Test Pump (the Product) is
used to check pressure measurement devices against master reference
gauges. The Product supplies the same pressure to both a reference
gauge and a device under test (DUT) to test the accuracy of the DUT.

Operation
Zero the Product before you do a pressure test.
Zero the Product
To zero the Product:
1. Turn , pressure release valve, counterclockwise until the valve is fully B
open.
2. Put one O ring in each of the output ports.
3. Connect the reference gauge to C E, output port 1, or , output port 2.
4. Connect the DUT to the open output port.
5. Select a pressure method to test:
●Positive pressure:
Fully turn A, pressure wheel, counterclockwise to decrease
pressure.
●Vacuum pressure:
Fully turn A, pressure wheel, clockwise to increase pressure.
6. Turn D, fine adjustment wheel, to the middle position.
7. Read the zero pressure from the reference gauge.
8. Turn B, the pressure release valve, clockwise until the valve is fully
closed.
Ascending Pressure
To check ascending pressure:
1. Zero the Product.
2. Select a pressure method to test:
●Positive pressure:
To generate pressure, turn A, pressure wheel, clockwise until the
pressure gets close to the target pressure.
●Vacuum pressure:
To generate pressure, turn A, pressure wheel, counterclockwise
until the pressure gets close to to the target pressure.
3. To get to the target pressure, turn D, fine adjustment wheel, to
increase or decrease pressure as needed.
4. Record the pressure from the DUT.
5. Repeat for each target pressure point up to the full scale.
6. Check descending pressure if needed.
Descending Pressure
To check descending pressure:
1. Zero the Product.
2. Generate ascending pressure greater than the target pressure or up to
the full scale.
3. Select a pressure method to test:
●Positive pressure:
To release pressure, turn A, pressure wheel, counterclockwise until
the pressure gets close to to the target pressure.
●Vacuum pressure:
To release pressure, turn A, pressure wheel, clockwise until the
pressure gets close to to the target pressure.
4. To get to the target pressure, turn D, fine adjustment wheel, to
increase or decrease pressure as needed.
5. Record the pressure from the DUT.
6. Repeat for each target pressure point down to zero.
Troubleshoot the Product
If the Product does not function as expected, try the steps in Table 3.
Table 3. Troubleshoot the Product
Problem SolutionCause
Difficult to maintain
pressure (leakage)
The pressure release valve is open. Close the pressure release valve.
The reference gauge is loose. Tighten the reference gauge.
The DUT is loose. Tighten the DUT.
An O ring is worn. Replace the O ring.
The threads on the Product, the reference gauge, or the
DUT are not smooth.
Apply thread seal tape to the threads of the reference gauge and the
threads of the DUT.
An impurity blocks the circulation of air. Repeatedly apply pressure and suddenly release the pressure until the
impurity comes out.
The DUT connector is too small for the output port of
the Product. Use an adaptor to connect the DUT to the Product.
Difficult to generate
pressure
The pressure release valve is open. Close the pressure release valve.
The reference gauge is loose. Tighten the reference gauge.
The DUT is loose. Tighten the DUT.
An O ring is worn. Replace the O ring.
There is a leak in the DUT. Test another DUT.
Valves or wheels do
not turn freely.
The valve or wheel is turned too tightly. Firmly grasp the valve or wheel and turn it gently.
The threads on the valves or wheels are dry. Apply grease to the threads on the valves and wheels.
