To fine tune the amount of sample uptake press the key
below the
plus or minus icon to increase or decrease the
amount of sample taken up. The recorded time will be
adjusted accordingly. Once the fine tuning is complete, or
if none is required, press the key adjacent to the
tick icon
to move to the next stage of the calibration sequence.
This stage allows an air gap to be added to the calibration
sequence. If an air gap is not required press the key below
the
000 icon to set the air gap to zero. If a previously
programmed air gap is to be used press the key adjacent
to the
double greater than icon to skip this stage and
retain the current air gap time.
To program an air gap remove the inlet tubing from the sample container and press the key adjacent to
the
single greater than icon. The sipper pump will start and air will be pumped through the tubing to
the flow through cell.
Once the required amount of air has been taken up press
the key adjacent to the
stop icon. The time taken for air
uptake is recorded.
To fine tune the amount of air uptake press the keys
below the
plus or minus icons to increase or decrease
the amount of air taken in. The recorded time will be
adjusted accordingly. Once the fine tuning is complete, or
if none is required, press the key adjacent to the
tick icon
to move to the next stage of the calibration sequence.
Once the sample uptake and air gap have been
programmed the preferred disposal of the sample can
be set. There are two options, the sample can either
be sent back to the sample container or it can be sent
to the waste pipe. Press the key below the
forward or
backward arrows to select what happens to the sample
after measurement.
If the original pump direction selected was forwards, selecting the forwards direction at this stage will
send the sample to waste and selecting the backwards direction will send the sample back to the sample
container. Once the required direction has been selected press the key adjacent to the
tick icon to save
the calibration sequence and return to the expanded operating menu. To exit the sipper calibration
sequence without saving any changes press the
back key at any point during the calibration sequence.
