Measuring Tips
•
Turn the meter on and off with the
I/O/EXIT
key.
•
To review a calibration, press the
REVIEW
key.
•
When using the dissolved oxygen probe, polarize the probe by
plugging it into the meter before attempting a calibration or
measurement. The length of time required for polarization depends
on how long the electrode has been unplugged. It can vary from 60
minutes (for a new probe) to a few seconds (if you momentarily
disconnect the probe). If the
CAL
and
?
icons flash after calibrating
the DO probe, the probe is not polarized.
•
Connect the pH electrode to the black connector, and the DO or
conductivity electrodes to the blue connector.
•
If the meter is not in reading mode, it may take a few key presses to
turn the meter off.
•
If the readings do not change when you move an electrode to a new
sample, the meter probably has the Display Lock set to
ON
for the
parameter you are reading. If the
Lock Icon
appears in the lower left
portion of the display, the setting is on. To change the setting, use
setup number 5. Or, press
READ
to initiate a new reading.
•
When calibrating pH or dissolved oxygen, make sure that the
instrument is displaying readings to the correct number of decimal
places for your needs. This will assure that your calibration is
sufficiently precise. To change the setting, use setup number 6.
