I am collecting data for a salt bath temperature comparison.  There are three
readings from the salt bath (controller, high and low) and 3 readings from a
test sensor.  The test sensor readings are subtracted from the bath readings
and the results are listed in cells J4, K4 and L4.  I am allowed +/- 2
degrees difference for the test to be acceptable.  In cell M4, I want the
results to show Accept or Reject.  What formula would I use to show Accept
for -2 to +2 in all of cells J4 thru L4 and Reject for any value exceeding -2
to +2 in any one of the cells J4 thru L4?
