The switching status of the electronics can be checked with closed housing (only plastic housing), see "function chart". Note: when placing the housing cover, make sure that the inspection glass is above the signal lamp (led) of the oscillator. To adjust vegacap 27, loosen first of all the four screw...

In exceptions, e.G. In pipelines or if the probe is mounted very close to the vessel wall, it can happen ath the probe signals already overfilling (covering) in uncovered condition. In this case, the switching point must be re-adjusted. For adjustment, the vessel must not be filled and the switching p...

Contact 4 against middle pin (1) the resistor must be 1 mohm. If the resistor is lower, this means moisture in the housing or a fault in the electrode insulation. A possible reason could be also a non-insulated electrode which is used in a conductive (humid) medium. If the resistor is higher or if t...

If the fault is eliminated after inserting the new oscillator, then you have to carry out a fresh adjustment with the new oscillator because oscillators have certain manufacturing tolerances. If the fault still exists or if no replacement oscillator is available, then you have to return the probe fo...
