Cal Points
Specify the number of pH calibration points you intend to
calibrate with. Select the number of calibration points
from 1 to 5 with preset buffer groups or from 2 to 5
points with custom buffer group.
For example, if you have selected the USA buffer group
which contains 5 standards, but you will only be using 3
standards (pH 4, 7, and 10), selecting 3 calibration
points here will speed up the calibration process—the 2700 will automatically
recognize calibration is finished after the 3
rd point has been completed.
Resolution
Select your desired pH resolution;
0.0, 0.00, or 0.000. Tip: Don’t choose more than you
really need—0.00 is the factory default setting since it is
most commonly used. Choosing 0.000 will lead to more
“unstable” conditions and cause a delay in obtaining the
final reading as the last digit (which is often not needed)
changes.
Alarm
The 2700 offers a visual and audible alarm to alert you
when the High or Low values that have been set from
this menu are exceeded.
“High Alarm” or “Low Alarm” will blink on the display if
the values are exceeded while simultaneously, a loud,
intermittent beeping sound is heard. The alarms will continue until the conditions
are no longer met, and will only be active during measurement mode.
Cal Due
When enabled, the “Cal Due” indicator blinks if the
number of days since the last calibration has been
exceeded. Set the number of days from 1 to 31.
