VEGA VEGAKON 66 with transistor output - Manual (Page 18)

The instrument is adapted to the medium, i.e. the transistor
blocks when max. level is reached. Only when decreasing the
min. probe, the transistor conducts again.
Example: A filling pump is switched on when the min. signal is
decreased, fills the vessels until max. signal is reached and is
then switched off.
The following settings apply to products with low conductivity
(<3 mS)
1 Empty the vessel until the min. measuring electrode is only
covered approx. 1 cm
2 Switch on voltage supply
3 Set the A/B switch to mode B
4 Set the rotary switch to position "TEST max."
5 Turn the rotary switch slowly anticlockwise until the red
LED lights
The instrument is adapted to the medium, i.e. the transistor
conducts at max. level. Only when decreasing the min. probe,
the transistor blocks again.
Example: An emptying pump is switched on when the max.
signal is reached, empties the vessels until min. signal is
reached and is then switched off.
In case of several measurement loops (same medium), the
adjustment of one instrument with medium is sufficient. The
determined switch position can be transferred to all other
instruments.
When the conductivity value is known, the switching point
adjustment can be carried out according to the setup in chart
"R
otary switch adjustment".
When exchanging the electronics module, it is sufficient to take
over the setting of the old electronics module.
