1.4.2
Test port
To attach the device under test, the test port uses “Quick fit”
pressure adaptors; see Section 1.5 (Accessories). These are
easy to remove, change and install; see Section 4.4
(Attach/Remove the device under test).
1.4.3
Hydraulic pressure release valve/reservoir access
This valve lets you release the pressure or seal the system.
Note:
To release all the pressure in the system, you must open
the refill valve (Section 1.4.4) one turn and then open the
pressure release valve one turn.
If you remove the valve (counterclockwise), you can also do
these operations:
•
add hydraulic fluid to the reservoir; see Section 4.2
•
drain all the hydraulic fluid from the instrument; see
Section 4.7
1.4.4
Hydraulic refill valve
When the refill valve is open, you have full control to increase
or decrease the pressure with the volume adjuster
(Section 1.4.5).
If you increase pressure and the volume adjuster gets to the
limit of travel, close the refill valve. This seals off all the
pressure in the test port and the pressure module connection.
You can then use the volume adjuster to refill the pressure
mechanism (Section 1.4.5).
Note:
To release all the pressure in the system, you must open
the refill valve one turn and then open the pressure release
valve (Section 1.4.3) one turn.
