WARNING REGARDING ISOLATION
Due to their non-conductive nature, 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-L probe head 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, in which case the ON led blinks. The threshold is set to work with alkaline
batteries, with other chemistry types this indicator may not work.
BATTERY REPLACEMENT
The probe head unit uses standard 1.5V AA batteries. Either alkaline or NiMh (2500mAh) type
can be used. To replace the batteries open the back cover of the unit. Follow the polarity sign
to replace the batteries and close the cover afterwards.
CARE AND MAINTENANCE
Clean only the exterior surfaces of the device using a soft cloth moistened with an alcoholic/
water solution. Do not use harsh chemicals, solvents, or abrasive cleansers. To prevent damage
to the measurement system, do not expose it directly to sprays, liquids, or solvents. Avoid
getting moisture inside when cleaning the exterior. Dry the probe before making any voltage
measurements. The probe is not waterproof.
