3.1.18 Vertical Stop Adjustment for Monoblock in Precision Top Loader Balance
NoteNote
NoteNote
Note:
If the Position Sensor Assembly is changed, it may be
necessary to readjust the vertical stop.
Adjusting Vertical Stop
1.Attach voltmeter to 2 pin connector located at
the top left corner of the Load Cell Board.
Apply power and turn on. Note voltage value.
2.Push down on overload protection until Lever
is at the top of the vertical stop and then
release overload protection. Voltage value
should be equal and opposite.
3.If the two voltage values either side of zero
are not of the same magnitude but, e.g. +2
Volts and -1.6 Volts, the vertical stop must be
adjusted until the values are symmetrical.
Voltage range: ±1.8 ... 2.5 Volts.
Asymmetry: max. 0.2 Volts.
4.To adjust vertical stop, turn vertical adjust-
ment screw ( Figure 3-15, item 3) and repeat
step 2 until readings are symetrical.
