Simulate 0°C at the instrument input with a suitable simulator; using the
1
and
2
keys, set on the display the correct value which corresponds to the
first calibration point.
Next simulate the second calibration point and set the correct value on the
display using the
1
and
2
keys. Press the CAL key to store the calibration
performed.
PROCEDURE FOR CALIBRATING THE INSTRUMENT
WITH ITS TEMPERATURE PROBE AND FOR STORING
THE DATA
To calibrate the instrument with its temperature probe, code C8, proceed
as follows: switch on the instrument with the ON/OFF key, holding down
the
key and the CAL key until all the symbols disappear. The message
CAL then appears, followed by 00; using the
1
and
2
keys, set the code
C8.
Connect the desired temperature probe to the instrument; insert it in the
calibration furnace at 0°C corresponding to the first calibration point, then
set the correct value on the display using the
1
and
2
keys.
Insert the temperature probe in the calibration furnace for the second cali-
bration point, then set the correct value corresponding to the second cali-
bration point on the display, using the
1
and
2
keys.
Press the CAL key to store the calibration performed.
CALIBRATING THE CONDUCTIVITY SECTION OF THE
INSTRUMENT
The instrument is able to recognize two standard calibration solutions: a
0.1 - mole solution of KCl and a 0.01 - mole solution of KCl. These solu-
tions are on sale in specialized shops or they may be prepared by fol-
lowing the procedures given below. Calibration is automatic when using
one of these two solutions.
Manual calibration is possible using a standard solution with a diffe-
rent conductivity from the solution used in automatic calibration.
