Performing an R-Cal For the First Time During Initialization
If you are performing an R-Cal for the first time as part of the Micro-
Tech initialization process, make sure that the R-Cal error is less than
0.75%. (If the error is greater than 0.75%, there may be a problem. See
the manual's the troubleshooting section on page 4-1 for additional
help.)
(The numbering below is continued from the previous page.)
6. Press the Yes button to set the span.
7. Press the Run button (in the display not the keypad) to return the
Micro-Tech to the Run mode. Congratulations! You are now ready
to put your Micro-Tech into operation.
Performing Any Subsequent R-Cal
Once you have initialized your Micro-Tech and are doing an R-Cal as
part of your weekly, daily, or other routing testing, proceed as follows.
In the example screen above, the display shows that the established span
is just 0.01% different from the previous span, meaning that both spans
are essentially the same and the scale is performing consistently. This
error is below the critical threshold error of 0.5% (or 0.25% for a Model
9201 integrator). As a result, the span should not be changed. Record the
span results for future reference.
However, if the error is greater than 0.5% (0.25% for Model 9201
integrator), there may be a problem—see the manual's troubleshooting
section in the following chapter for additional help. Record the span
results for future reference.
