Assembly
Refer to figure 1 - Assembled Balance
1.
Withdraw the balance from the carrying case and place on flat and
level surface.
2.
Assemble the stand by screwing the support stem into the
mounting block on the corner of the stand.
3.
Level the balance using the adjustable feet, and check with the
built in level indicator.
4.
Carefully withdraw the target and container assembly from the
carrying case.
5.
Place the container on top of the stand, taking care to ensure that
the weighbridge spindle is engaged on top of the loadcell and that
the container is central between the location pegs of the stand.
6.
Select a suitable workpiece clamp and fit to the stand support stem
(the unit is supplied with quick release clamps for use with EMS
heads and an adjustable clamp for use with other styles and sizes
of heads).
7.
The target container can now be filled with suitably degassed
water. (To degas the water, it should be boiled and left to cool in a
suitable covered container - see IEC 150.) Sodium Sulphide (at a
ratio of 4g/litre) may be added to help degassing the water if
required.
8.
Once the container has been filled with degassed water, a suitable
centralising plate may be fitted. (There are five sizes of plates for
use with various EMS heads.)
9.
If the source being tested cannot be used with a suitable
centralising plate then ensure that the source is central to the target
otherwise inaccurate readings may be obtained.
10. Before use, the target frame should be checked to see that it is not
in contact with the head centralising plate.
11. Connect the output lead from the mains adaptor to the socket on
the rear of the balance. Connect the mains adaptor to a suitable
mains outlet.
The PRECISION ULTRASOUND BALANCE is now ready for use.
