blink signalling an error. The calibration process will take a few
seconds. If the procedure completed successfully the CAL led
will turn off, otherwise it will blink and remain in that state. In this
case, check the batteries in the probe head and rerun calibration.
WARNING REGARDING ISOLATION
Due to their non-conductive nature, the fiber optic cables
provide excellent isolation between probe head and receiver.
However the probe head is floating at the same potential of the
measured conductor. Thus the whole body of the XFVP probe
head including the metallic bayonet connectors can be at
hazardous potentials.
It is advisable to install a voltage detector/indicator on the measured line that provides visual
and clear indication about the presence of potentially dangerous voltages. SAKER offers the
MVD and MVDZ series of medium voltage presence detectors.
LOW BATTERY CONDITION
The probe head will measure the voltage of the batteries to warn the user in case of a low
battery condition. The signalling threshold has been adjusted for typical alkaline AA batteries.,
for other chemistries it may not work properly. A single red led is used at the receiver to display
this condition.
In case of a battery low event the BATT LOW led will quickly blink one time followed by a 4
second pause in the following way:
