7-3 Calibration Procedures
After having started a calibration watch the
screen for information about the status:
The first lines shows the gas (channel) to be
calibrated and the currently measured con-
centration (at the end of zero calibration this
value should be set to about "0").
The line PROCEDURE shows what's currently
happening (Zero 1 = calibration for channel 1
ongoing; None= calibration finished), while the
last line shows the remaining time till end of
calibration (countdown starting from 2 times
"t
90
for calibration", which is 15 seconds).
CO2.1 0.000 ppm
Procedure Zero 1
Time 10 s
Dual channel instrument:
Optional gas component selection menu -
Select the component to be calibrated.
CANCEL calibration!
START calibration!
SpanGas 20.000 ppm
CO2.1 16.200 ppm
Before selecting any further line
make sure the required calibra-
tion gas is applied and flowing!
The first line gives you the choice to cancel the
procedure now.
Select the second line to start the calibration.
Line 3 shows the calibration gas setup (here:
required span gas concentration is 20 ppm),
while line 4 shows the currently measured gas
concentration.
When finished press the LEFT key two times
to return to either
the component selection menu (dual channel
analyzer only), if required select the second
channel and perform the steps above to zero
calibrate this channel, too,
or
to return to the controls menu, which allows
you to start a span calibration. The procedure
and screens look similiar to those of a zero
calibration: Select SPAN CALIBRATION.
