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.
