better the temperature correction, the lower the error. The only way to eliminate this error is not to use the 

correction factor, acting directly on the sample temperature. 

 

Select 0.00% / °C as the temperature coefficient to deactivate the compensation. The displayed Conductivity 

value refers to the temperature value measured by the probe and not related to a reference temperature.

VIEW:

 The following screens will scroll automatically on the display: 

•

 

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

•

 

Second and possibly third, fourth and fifth screens: value of the actual cell constant in the 

measurement range indicated by the beaker. 

Note

: The instrument accepts calibrations with a maximum tolerance of 40% on the nominal 

value of the cell constant only.

IMPORTANT:

 Make sure that the printer is connected and turned on and that the paper roll and cartridge are 

correctly positioned. For more information, refer to the printer user manual. 

 

NOTE:

 Use the original printer specified by the manufacturer only. For information, contact your local distributor. 

 

P3.7 COND Calibration expiration 

 

Access this menu to set a calibration deadline; this option is fundamental in GLP protocols. 

•

 

By default, no calibration deadline is set. Use the directional keys to select HOURS or DAYS and access 

with

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

. 

•

 

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

The string “

MAKE A NEW CAL

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

able to work again.
