Multi 3500i Operation

Note

For single-point calibration, the instrument uses the Nernst slope

(-59.16 mV/pH at 25 °C) and determines the asymmetry of the elec-

trode.

8 Wait for the end of the AutoRead measurement or Terminate

AutoRead and accept the calibration value with

<MENU/ENTER>.

The calibration display for the next buffer appears.

9 For single-point calibration, select Exit with one point calibra-

tion with <▲><▼> and confirm with <MENU/ENTER>.

The calibration is completed as a single-point calibration.

The new calibration values are displayed as a message (

i).

You have the following options:

z Accept the new calibration values with <MENU/ENTER>.

Subsequently, the calibration record is displayed and output

to the interface at the same time.

z To switch to the measured value display without

accepting

the new calibration values, press <M> or <ESC>.
