30 Capacitive electrodes EK with signal conditioning instrument
Set-up
Signal conditioning instrument
VEGAMET series 300
When the electrode is not already pread-
justed by VEGA, you have to choose the
measuring range.
• Set the changeover switch on the capaci-
tive electrode EK according to the table on
the previous page.
• Turn the potentiometer for the full adjust-
ment approx. 22 turns clockwise.
• Empty the vessel to the requested min.
level.
• Turn the potentiometer for the empty ad-
justment anticlockwise until the pointer of
the indicating instrument is at 0.
• Fill the vessel to the requested max. level.
The indication shows more than 100 %.
• Turn the potentiometer for the full adjust-
ment anticlockwise until the pointer is at
100 %. When the indication cannot be set
to 100 %, proceed as follows:
- when the indication does not reach
100 %, you have to set the changeover
switch on the electrode one stage lower.
- when the indication exceeds 100 % and
cannot be reset, you have to set the
changeover switch to the next higher
stage.
In both cases you have to repeat the ad-
justment.
Signal conditioning instrument
VEGAMET 614, VEGAMET series 500
When the electrode is not already pread-
justed by VEGA, you have to choose the
measuring range.
• Set the changeover switch on the capaci-
tive electrode EK according to the table on
the previous page.
• Carry out the adjustment on the signal
conditioning instrument (see operating
instruction of the signal conditioning instru-
ment: "Adjustment with medium“).
- when the signal conditioning instrument
displays the fault signal E014, this mes-
sage is explained in the operating in-
struction of the signal conditioning
instrument under "Error code“. When
sensor and connection line work without
problems, probably a wrong range of
the capacitive electrode was chosen. Set
the changeover switch to the next higher
stage.
- When the signal conditioning instrument
displays the fault signal E017, set the
changeover switch on the electrode to
the next lower stage.
Signal conditioning instrument
VEGAMET series 600
(except VEGAMET 614)
When the electrode is not already pread-
justed by VEGA, you have to choose the
measuring range.
• Set the changeover switch on the capaci-
tive electrode EK according to the table on
the previous page.
• Carry out the adjustment according to the
operating instruction of the signal condi-
tioning instrument (see operating instruc-
tion of the signal conditioning instrument
"Adjustment“).
When the indication cannot be set to 100 %
(10,0 V), proceed as follows:
- when the indication does not reach
100 % (10,0 V), you have to set the
changeover switch on the electrode to
the next lower stage.
- When the indication exceeds 100 %
(10,0 V) and cannot be reset, you have
to set the changeover switch of the elec-
trode to the next higher stage.
In both cases you have to repeat the
adjustment.
