Warnings and cautions
Avoid possible damage when suddenly apply pressure to low pressure and small
chamber gauges.
Do not exceed the safety pressure limit（18MPa）.
Compressed air may cause problem in explosive or corruptive environment.
Do not shift the selector to vacuum mode under pressure.
Do not over tighten connectors to avoid any damage.
The pump could store in the dry and non-corruptive environment.
Any safety problems or damages caused by incorrect operation, are beyond ConST
group's responsibility.
Specification
Pressure range: （-0.095 to 12）MPa
Temperature: （0~50）℃
Humidity: < 85%RH
Adjusting fineness: 10Pa

Troubleshooting
Problems
Hard to use pressure lever
Hard to pressurize
Hard to use fine adjust
Not easy to turn the fittings
Solutions
Causes
The isolating valve is not open.
Open the isolating valve.
A. Release valve is not closed.
Close the release valve.
B. The sealing ring is broken or loosen.
Replace sealing ring (PR#:ZL200620119357.2).
C. P/V selector is in wrong position.
Pressure: pull it out; Vacuum: push it in.
D. Pipeline jamed with impurity.
Open the Clean-out bolt and clean.
A. The isolating valve is not closed.
Close the isolating valve.
B. The gauges is not tightened.
Tighten the reference gauge or the gauge under test.
C. The sealing ring is aged or frayed.
Replace sealing ring.
D. The thread surface is not smooth.
Put in a Teflon seals and turn it tightly.
E. The connector type is unmatched.
Use the right and suitable adapter.
F. The impurity blocks the air routine.
Repeat pressurizing several times and then release it suddenly, make airflow to bring the impurity out.
A. Too tightly turned last time!
Do not apply much force to close the fittings and valves.
B. The new pump is not smooth.
The new pump needs time to abrade.
C. The threads have no lubrication.
Lubricate the thread.
