EL6010-Uras14: Measure Calibration Cell

Definition
When should the

measured?

Measuring the calibration cell determines what calibration cell "deflection" is
equivalent to the test gas calibration reading. This "deflection" is stored as the
calibration cell "set point".
We recommend measuring the calibration cell once a year. Measurement of the
calibration cell is also recommended after a user-set measuring range (see page
29) is calibrated for the first time with test gases and subsequently whenever the
test gas is changed.
Prior to measuring the calibration cell, the zero and span point of the applicable
sample components must be calibrated with test gases.
During calibration cell measurement the zero gas supply must be turned on.
Step Action
1 Select the Calibrate
menu.
2 Select Measure
calibration cell.
3 Turn on the zero gas
supply.
4 Start measurement if the
measured value reading
is stable.
5 Measurement in
progress.
6 Accept the set point.
7 Press the Back key to
return to displaying
measured values.
