4. Get the load cells you are using (one or two). Screw the connector on each load
cell cable into the connector on the calibration module.
5. Plug in your AutoSet calibration unit if you have not done so. If your unit does
not have a plug, connect wiring to an AC outlet, then apply power. Make sure
power at outlet is off before connecting wires.
WARNING
PREVENT SHOCK
If your AutoSet does not have a plug and you wire it to a power
source, make sure power at that outlet is off before you connect the
wires.
6. Check the AutoSet displays. Once AutoSet has power, the displays will show
numbers, dashes, or letters (it does not matter what at this point). Recheck all
connections if displays do not light up.
7. Familiarize yourself with the location of the switches and dials inside the box. See
Figure 2-2 in Chapter 2 for a drawing of the components inside the box.
8. You must set the full scale tonnage on the AutoSet calibration unit to 2 times the
tonnage of one load cell.
Even if you are using two load cells, you still set this
number to 2 times the tonnage of 1 load cell.
Determine the number you will use for your setting. Here are two examples of
how to determine the correct number:
Example 1. You are using one 100 ton load cell for calibration. The full scale
tonnage must be set to 200.
Example 2. You are using two 100 ton load cells for calibration. The full
scale tonnage must be set to 200.
9. Set full scale tonnage as follows:
Find the three blocks in a column with white dials on them. See Figure 3-2. They
are at the right middle of the box.
