Meter and Autosampler Operation
1 . Prepare the samples, beakers and tray . Make sure that the autosampler function
is set to On in the setup menu .
The first one to five beakers are used as rinse beakers, depending on the
number of rinse beakers selected in the setup menu . The next zero to three
beakers are used as pH, ORP or ISE calibration beakers, depending on the type
of calibration and number of beakers selected in the setup menu . The next zero
to three beakers are used as conductivity calibration beakers, depending on the
number of beakers selected in the setup menu .
2 . Press
to initialize the autosampler .
3 . The autosampler will move the electrodes to the rinse beaker(s) for the time
specified in the setup menu .
4 . The autosampler will move the electrodes to the sample beaker and the meter
will take a measurement .
5 . The actual measurements will be shown on the display . If a stirrer probe is in
use, the stirrer will automatically begin stirring when the measurement starts
and end stirring when all measurement parameters are stable . When a stable
reading is achieved, it will be saved in the datalog and/or sent to a printer or
computer, depending on what was selected in the setup menu .
6 . The autosampler will move the electrodes to the rinse beaker(s) for the time
specified in the setup menu, move the electrodes to the next sample beaker
and then the meter will take a new measurement . The autosampler and meter
will continue this process until all sample beakers have been measured .
7 . To repeat the same autosampler program, replace the tray and press
.
To omit the calibration beakers, change the number of rinse beakers or modify
another setup parameter for the autosampler, refer to the Meter Preparation
for Operating the Autosampler section .
