Measurement Procedure
As needed, customize the information shown in the measurement mode using the
Instrument
Settings
setup menu. If two or more modules are connected to the meter, while in the
measurement mode press the channel key until the desired combination of meter channels are
shown. Select the read type for all meter channels shown in the measurement mode.
Prepare the electrodes according to the instructions in the electrode user manuals. Connect the
electrodes to the module inputs on the displayed channels. Make sure the electrodes are
properly calibrated and working correctly.
1.
Rinse the electrodes with distilled water or appropriate solution, blot dry with a lint-free
tissue and place into the sample.
2.
Start the measurement and wait for the reading to stabilize or reach the predefined time.
a.
Auto-Read: Press the measure (esc) key to start the measurement. If using a stirrer
probe, the stirrer probe will start stirring when the measure (esc) key is pressed and
stop stirring when the measurement stabilizes.
b.
Timed: Measurements will start immediately when in the measurement mode. If using a
stirrer probe, press the stirrer key to start and stop stirring.
c.
Single-Shot: Press the measure (esc) key to start the measurement. If using a stirrer
probe, the stirrer probe will start stirring when the measure (esc) key is pressed and
stop stirring when the predefined wait time has elapsed.
d.
Continuous: Measurements will start immediately when in the measurement mode. If
using a stirrer probe, press the stirrer key to start and stop stirring.
3.
Once the measurement is stable or reaches the set time, record all applicable parameters.
a.
Auto-Read: Once the measurement is stable, it will be locked and held on the display
and the AR icon will remain solid. If the data log function is enabled, the measurement
will be exported to the data log.
b.
Timed: Measurements will be recorded at the predefined time interval. If the data log
function is enabled, the
icon will be shown when each time interval has elapsed and
the measurement is exported to the data log.
c.
Single-Shot: Once the predefined wait time has elapsed, the measurement will be
locked and held on the display. If the data log function is enabled, the measurement will
be exported to the data log.
d.
Continuous: The flashing Stabilizing icon will update to the solid Ready icon when the
measurement is stable. If the data log function is enabled, press the log/print key to
export the measurement to the data log.
4.
Remove the electrodes from the sample, rinse with distilled water or appropriate solution,
blot dry with a lint-free tissue and place into the next sample.
5.
Repeat steps 2 through 4 for all samples. When all samples have been measured, store
the electrodes according to the instructions in the electrode user manuals.
