Sealing of NMS5

NMS5 can be sealed, and data can be made unchangeable for custody transfer purposes as follows.
Sealing of NMS5 procedure
1. Set OPE. DENSITY at GVH278 as the liquid density (if the density is expected to change during
operation, set the average value.).
2. Turn off the power supply, open NMS5.
3. Turn the micro switch to the "on position" on the printed circuit board TCB (see figure below).
NMS5 will then enter "write-protect" mode and not accept any further level, weight, or density
data changes.
This completes the sealing of NMS5 procedure.
