470 Method
I(pol)
-125.0 ... [ 5.0 ] ... 125.0 µA (Titrando, increment = 2.5 µ A)
-127 ... [ 5 ] ... 127 µA (Titrino, increment = 1 µ A)
The polarization current is the current applied to the polarized electrode
during a voltametric measurement.
Electrode test
on, [ off ]
Switch on/off the electrode test for polarized electrodes. This test is carried
out during the transition from an inactive condition to a measuring condi-
tion. It is checked that the electrode is properly connected and that no
short-circuit is present.
Temperature measurement
Type of temperature measurement (Titrando only):
continuous
A temperature sensor must be connected. The temperature is then meas-
ured continuously.
[ automatic ]
If a temperature sensor is connected, the temperature will be measured
continuously. Otherwise the temperature manually entered under
Tempera-
ture (see Measuring parameters) will be used.
off
The temperature will not be measured. The temperature manually entered
under
Temperature (see Measuring parameters) will be used.
Stirrer
Stirrer
[ 1 ] ... 4, off (Titrando only)
Selection of the stirrer. off means that no stirrer will be used.
Stirring rate
-15 ... [ 8 ] ... 15 (Titrando only)
Setting the stirrer speed. The direction in which stirring takes place changes
as the sign in front of the stirrer speed changes.
Switch off automatically
[ on ], off (Titrando only)
The stirrer is automatically switched off at the end of the command if this
option is activated.
