3-10 Calibration
9.
Set Mode switch #3 for the display option you want, referring to Figure 3-5 and Table 3-2.
10.
Power down the AutoSet calibration kit, then power it back up to reset the unit and
activate your tonnage and decimal point settings.
11.
Move the lever on the three-position switch labelled “S3” on old-style boards (see
Figure 3-2) or “S2” on new-style boards (see Figure 3-3) to the “ZERO SET” position,
and check the channel Load LED displays on the AutoSet front panel.
If you are using one load cell for calibration, the value shown in the left Load display must
fall b50 and -50. If you are using two load cells, the number in both left and right
Load displays must fall in the ±50 range.
If the Load displays are not within this range, there is a problem with your calibration unit.
Call Wintriss Tech. Support for assistance.
12.
Move the lever on switch S3 or S2 to the “CALFACTOR” position.
13.
Locate the two load cell gain adjustment potentiometers labelled R17 and R25 to the left
of the strain link inputs at the bottom center of the enclosure. A tiny screw protrudes from
the upper left corner of each potentiometer, as shown in Figure 3-6.
14.
If you are using one load cell for calibration, turn the screw on gain adjustment
potentiometer R17 clockwise or counterclockwise until the left channel Load LED display
reads 157±2.
If you are using two load cells for calibration, turn the screws on both gain adjustment
potentiometers (R17 and R25) until both channel displays read 157±2.
To calibrate the press in metric tons, set the left channel to 173±2 for one load cell or both
left and right channels to 173±2 for two load cells.
