INSTRUCTIONS FOR USE
Situations To Avoid
Within certain situations and because of various system configurations, electrical field
interference capable of affecting the operation of the FireFly Voltage Detector may
occur. Within these areas it is imperative that you be aware of and identify all such
conditions which may exist. Some examples of these situations are discussed here.
1) 90° CORNER CONFIGURATIONS:
Using the FireFly Detector on the inside of 90°
corners may cause reduced voltage sensitivity or a failure to indicate voltage.
2) SAME PHASE INTERFERENCE:
When two conductors of the same phase are
in close proximity to one another, the field generated could shield the FireFly
Detector, causing it not to operate.
3) OPPOSITE PHASE INTERFERENCE:
This condition may occur when testing
a grounded and de-energized conductor which is in close proximity to
a live, ungrounded conductor. In this situation the FireFly Detector may indicate live
voltage when the conductor being contacted is at ground potential.
NOTE:
Only use the FireFly Detector within the voltage range specified on the product
label. Do not use the FireFly Detector above or below the product label rating.
DANGER:
Never allow the body of the FireFly Detector to bridge across, or come
in contact with, another conductor or grounded point.
