A span calibration should be performed after a successful zero calibration.
From the
Manual Calibration menu press
to access the Manual Span Calibration screen.
Make sure the highlighted span gas value (see above) matches the value on the certificate
for the span calibration gas being supplied to the analyzer. If the span gas concentration
does not agree with the value on the certificate, press
and change the concentration
to match it. Press
again to close the span gas concentration field.
Make sure the analyzer is in the range you wish to calibrate. Use the Up/Down arrows
to go to the desired range. The illustration shows the range (R2) next to the
maximum range limit (30.00 ppm).
Introduce span gas into the rear of the analyzer. Press
to go to the
Diagnostic
Values
screen to view the current Diagnostic values. Check the temperatures and
pressures to be sure they are within their limits. If all diagnostic values are within their
limits, press the
button to return to the Manual Span Calibration screen.
