Last calibration data
Access this menu to get information on the last calibration performed.
Selecting "View", a report appears on the display with the following
information regarding the calibration currently in use:
CALIBRATION DATE / CALIBRATION TIME / TEMPERATURE / DHS MODEL
IF PRESENT / OFFSET / SLOPE % for each range.

innovative graphic representation regarding the calibration conditions,
which allows you to intuitively understand the status of the sensor.
Due calibration
Access this menu to set a calibration deadline; this option is very important in GLP protocols.
By default, no calibration deadline is set; use the directional keys
which must pass between the two calibrations e confirm with button
When a calibration deadline for a parameter is set, the icon
measure mode.
When the calibration deadline is activated, the instrument prevents further measurements, until the
calibration is renewed, or the deadline deactivated.
The error icon
calibration of the pH sensor to be able to work again.
Set stability criteria
To consider the reading of a value truthful, we recommend waiting for the measurement stability, indicated
by the icon
.
Access this menu to change the measurement stability criterion:
"Medium" (default value): readings included within 0.6 mV.
"High": choose this option to display the stability icon only in conditions of high measurement stability,
readings included within 0.3 mV.
"Tit" (titolation) no stability criterion is activated; the reading will therefore be "continuous".
With this active option, the icon
however the response time of the device is reduced to the minimum, as it is a simultaneous measurement.
Set pH alarm
Access to set threshold alarm for measuring the minimum and/or maximum pH value.
This option is indicated by the appearance of the icon on the display
When the set threshold is exceeded, the instrument will report the alarm to the user in the following ways:
The measured pH-value turns into red.

The calibration report has been designed to provide the user
with an immediate view of the calibration conditions, in fact,
the closer the blue rectangle (actual calibration data) is to the
outside of the graph, the closer to ideality is the calibration and
electrode conditions; vice versa, the condition worsens if the red
rectangle is closer, which represents the limit of acceptability
recommended by the supplier.
The graph shows the data relating to the offset, the average
slope, the sensor settling time and how many hours have
passed since the last calibration.
