Setting Min/Max Display Value J1, J2, J3 (see Figure 2 & 3):
If:
The minimum display is ≤0 or minimum display is > 0 and the (maximum
display minimum display) ≥ 5;
Then:
J1, J2 & J3 should be all set to the top jumper (see Figure 2).
Figure 2
If:
The minimum display is > 0 and the (maximum display minimum
display) <5;
Then:
J1, J2 & J3 should all be set to the bottom jumper (see Figure 3).
