Access this menu to get information about the last calibration performed. The following screens will

automatically scroll on the display:

•

First screen: CALIBRATION DATE and TIME and beakers indicating the buffers used.

•

Second screen: OFFSET value of the electrode expressed in mV.

•

Third and possibly fourth screen: Slope% in the measuring range (one Slope% only if two calibration

points are performed, two Slope% if three points are performed).

Note

: The instrument accepts calibrations with pH electrodes with Slope% between 80 - 120% only.

Outside this range of acceptability, the instrument does not allow to end the calibration and displays the

error message

SLOPE OUT OF RANGE

P1.7 pH calibration deadline

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 to select HOURS or DAYS and access

with button

. Use the directional keys to change the number that appears in the center of the

display, entering the hours or days that must elapse between two settings, and confirm with

•

If a calibration deadline is set, the icon

is present on the display in measure mode.

•

When the calibration deadline is activated, the instrument prevents further measurements.

The error icon

and the icon representing the calibration deadline

flash on the display.

The string “

MAKE A NEW CAL

” invites the user to perform a new calibration of the pH sensor to be

able to work again.

Press the key

to start the calibration.

P1.8 Reset of the pH parameter

If the instrument does not work perfectly or incorrect calibrations have been carried out, confirm

YES

with

the button

to take all the parameters of the pH menu back to the default settings.

IMPORTANT:

The factory reset of the parameters

DOES NOT

erase the stored data.

P1.9 Temperature calibration

All the instruments of this series are pre-calibrated for a correct temperature reading. However, if there is a

difference between the measured and the real temperature (usually due to a probe malfunction), it is

possible to perform an offset adjustment of + 5°C.

Use the keys

and

to correct the temperature offset value and confirm with

•

Automatic pH calibration

Example: three-point calibration with USA type buffers (7.00 / 4.01 / 10.01).

•

measure mode

press the key

to enter calibration mode.
