12.2 Weight calibration

Weight table calibration must be done after completing hall sensor adjustment. The calibration proce-
dures will vary depending on the measurement specifications. When NMS5 is only for level measure-
ment, use 12.2.1 Weight Calibration (Standard) procedure. When NMS5 is for level, density, and inter-
face measurement, use 12.2.2 Weight Calibration (Density) procedure.
12.2.1 Weight calibration (Standard)
CAUTION
Make sure that wind and vibration may affect weight table calibration.
It is not necessary to perform weight calibration for Startup "All-in-one" (displacer attached) shipments.
1. Enter Access Code 51 at GVH039.

2. Confirm the following status. GVH340 wire
drum circumferential (engraved on wire drum),
GVH341 wire weight standard SUS = 2.50
250.2g
PFA=4.55, and GVH342 displacer weight
(engraved on displacer)
3. Confirm each engraved data in the wire drum
and the displacer and values in Matrix are the
0 1 2
same.
4. If the matrix data is different from the engraved
xxx.xxx x.xx xxx.x
data, input the engraved value at Matrix.
5. Select STOP at GVH020.
6. Set the value of 0.0 at GVH379.
7. Select ON at GVH373.
• NMS5 automatically move the displacer up and
down and perform the calibration, and stops.
8. Enter No "-" at "Displacer Down? +/-" for calibra-
tion window.
• When inputing "-" displacer stop current position.
When inputting "+", displacer moves down to
300mm and stops.
