Autosampler Operation
Running the Autosampler
1. Set all of the autosampler parameters in the autosampler setup menu. Refer to the
Autosampler Setup Menu
section for detailed instructions.
2. Set the meter display so only the channel or channels that will be run on the autosampler
are displayed. Press the channel key to select a dual channel display for running both
channels on the autosampler, a single channel display for running channel 1 on the
autosampler or a single channel display for running channel 2 on the autosampler.
Note: The meter will log the data points for both channels during the autosampler run if the dual
channel display is selected. The meter will log the data points for only one channel if the single
channel display is selected.
3. Ensure that all of the electrodes are connected to the meter inputs that correspond with the
channel(s) that will be run on the autosampler. If the stirrer probe, Cat. No. 096019, will be
used with the autosampler, connect the stirrer probe to the stirrer input on the back of the
autosampler.
4. Set the method(s) for the channel(s) that will be run on the autosampler. Methods must be
assigned to the channel(s) that will be run on the autosampler before the autosampler can
be run. Make sure to assign the measurement mode and electrode ID for the channel(s)
that will be run on the autosampler.
The operator may select Current Settings as the method and the meter will use the current
meter settings to run on the autosampler. If Current Settings is selected as the method,
calibrations cannot be run on the autosampler and the samples will be measured using the
last saved calibration.
Note: A method can be selected when the autosampler setup parameters are entered, but any
method editing must be done from the method list. Calibration values from the last calibration
performed in the method are stored to the method, so calibrations can be performed on the
autosampler.
5. To begin an autosampler run, press the auto key, verify that all of the autosampler setup
parameters are correct and press the f3 (start) key.
a. During the autosampler run, press the f1 (pause) key to pause the run. Press the
f1 (resume) key to continue the autosampler run at the point where it was paused,
press the f2 (auto) key to access the autosampler setup parameters or press the
f3 (end) key to cancel and end the autosampler run.
b. Press the f3 (end) key to abort the autosampler run. The autosampler arm will return to
home position and the meter will return to the measurement mode.
6. Once the autosampler run is complete, another autosampler run can be started or the meter
can be used as normal. The method that was selected for the previous autosampler run will
be used for the next run, unless the operator changes the method in the autosampler setup
menu.
