12) Zero
Revs
- When AUTO ZERO is pressed, the WP20 will zero the scale. For this
Parameter enter the number of belt revolutions to be used for an Auto Zero cycle. In general, the
more time (more belt revolutions) allowed for an AUTO ZERO cycle, the more accurate it will
be. While the Auto Zero cycle is being performed, the WP20 spends time “learning” about the
belt splices and other inconsistencies in the system. Enter a value that allows at least two minutes
of run time. AUTO ZERO is discussed further in the Calibration Section 7.04.
13) Span
Revs
- When AUTO SPAN is pressed, the WP20 will re-span the scale using the
calibration weight(s) or a calibration chain. Enter the number of belt revolutions to be used for an
AUTO SPAN cycle. In general, the more time (more belt revolutions) allowed for an AUTO
SPAN cycle, the more accurate it will be. Enter a value that allows at least 2 minutes of run time.
AUTO SPAN is discussed further in section 7.04.
14) Rate
DP
- Enter the desired decimal point position for the RATE window. Set to Ones
when the maximum RATE will be greater than 100, set to Tens when the maximum RATE will
be less than 100, and set to Hunds when the maximum operating RATE will be less than 10. The
decimal point positioning for various positions will appear as:
Ones
0000
Tens
000.0
Hunds
00.00
If the RATE exceeds what will fit in the display, a series of dashes will appear in the RATE
window and looks like ---- .
15) Rate
Damp
- Enter the damping factor for the RATE display. Damping makes the RATE
display more stable so the numbers do not change faster than they can be read. The higher the
Damping Factor the more stable the reading. RATE damping does not affect the TOTAL or the
accuracy of the system. Note that the higher the damping, the slower the RATE display will
update after changes occur in the actual RATE. A typical value for Rate Damp is 30. Set to zero
to turn off damping.
16) Speed
DP
- Enter the decimal point position for the belt SPEED display. Set to Ones
when the maximum belt SPEED will be greater than 100, set to Tens when the maximum belt
SPEED will be less than 100, and set to Hunds when the maximum belt SPEED will be less than
10. The decimal point positioning for various positions will appear as:
Ones
0000
Tens
00.0
Hunds
0.00
If the SPEED exceeds what fits in the display, a series of dashes will appear in the SPEED
window and looks like ------.
17) Speed
Damp
- Enter the Damping Factor for the belt SPEED display. Damping makes
the SPEED display more stable so the numbers do not change faster than they can be read. The
higher the Damping Factor the more stable the reading. SPEED damping does not affect the
RATE, TOTAL, or the accuracy of the system. Note that the higher the damping, the slower the
SPEED display will update after changes occur in the actual SPEED. A typical value for Rate
Damp is 30. Set to zero to turn off damping.
