Note
Calibration is automatically completed after the last buffer of a buffer
set has been measured. Then the calibration record is displayed.
The calibration line is determined by linear regression.

Carrying out a manual calibration (VariCal)
Make sure that in the sensor menu,
Buffer
menu, the
VariCal
buffer set
is correctly selected (see page 28).
Use any one to five buffer solutions in ascending or descending order.
Note
If single-point calibration was set in the menu, the calibration procedure
is automatically finished with the measurement of buffer solution 1 and
the calibration record is displayed.

When measuring without temperature sensor:
Measure the temperature of the buffer manually and enter it
with
<

.
18
Start the measurement with
<ENTER>
.
The measured value is checked for stability (stability control).
The [AR] status indicator is displayed. The measured parame-
ter flashes.
19
Wait for the measurement with stability control to be completed
or terminate the stability control and take over the calibration
value with
<ENTER>
.
The calibration display for the next buffer appears (voltage dis-
play).

If necessary, use
<M>
to finish calibration or
switch to calibration with the next buffer with
