3-4 Calibration
9.
Tighten the screws evenly around the perimeter of the strain link to a specification of 150
in./lbs.
10.
Check the strain link’s offset value on the Load LED display on the AutoSet front panel.
11.
Using the potentiometer adjustment screw (refer to Table 3-1), adjust the strain link offset
until it falls b50 and -50. Try to adjust the offset as close to zero as possible.
12.
If you cannot adjust the strain link’s offset reading to within the ±50 window, loosen the
mounting screws and repeat steps 9 through 11.
13.
Replace the strain link cover, if necessary, when you have finished zeroing the strain link.
14.
Zero the remaining strain links, repeating steps 4 through 13. Start with any strain link
that is generating a blinking “HI” or “LO” message on a Load LED display and an “Err”
message on the corresponding Setpoints LED display. When no strain link is generating a
flashing “HI” or “LO” message, proceed with zeroing the strain links that remain.
15.
When all the strain links have been zeroed, turn the S102 switch on the AutoSet processor
board to the “OPERATE” position (see step 3).
Using a Voltmeter to Zero Strain Links
Perform the following procedure if the AutoSet LED displays cannot be used to zero strain
links (i.e., displays are too far away or are obstructed).
1.
On the AutoSet processor board, place the leads of a voltage meter on the pins holding the
white and green wires (i.e., pins 2 and 3) in the cable from the strain link you are zeroing.
2.
Adjust the potentiometer screw on that strain link until the reading shown on the voltmeter
is close to 0 Vdc.
If after several attempts you cannot get the Load display to read in the ±50 range, the
strain link mounting holes may not have been drilled at right angles to the mounting
surface, or the strain link may not be working properly. Contact Wintriss Tech. Support for
assistance.
When multiple strain links have zero adjustment readings outside the ±99 window, the
Load and Setpoints displays for only one strain link will show the “HI”/“LO” and “Err”
messages, the LED displays for the other strain links remaining blank. When that strain
link has been adjusted to a value within ±99, the Load and Setpoints displays for one of
the remaining out-of-range strain links will show the “HI”/“LO” and “Err” readings.
The displayed voltage does not have to be exactly 0 Vdc. If the reading on the voltmeter is
b 0.70 and - 0.70 Vdc, the strain link can be considered zeroed.
