E-32 Blank Error. The meter is unable to calculate a
Orion 710Aplus, blank value. This error occurs
720Aplus, during a three or more point
and 920Aplus calibration, when one solution has
been defined as zero concentration
and the actual concentration of the
blank is substantially greater than the
least concentrated standard. This can
also occur during a one or two point
calibration if one of the standards
is defined as zero.
1. Check to make sure electrode(s)
were placed in the proper
standards and blank solution
and recalibrate.
2. Repeat calibration using fresh
blank and standards.
3. Recalibrate using two standards
of known concentration other
than zero.
