Detection Levels - AEMC 275HVD Manual De Instrucciones

Detection Levels

The 275HVD is used by moving it closer to the live conductor until the
buzzer and light warnings are triggered. It is designed to detect at a lower
voltage than the range setting.
The following data is considered as typical response for the 275HVD. Vari-
ations may occur from unit to unit. As a general rule, in a "clean" environ-
ment, the 275HVD will trigger @ 45 to 65% of the voltage range at 4"/10cm,
and detected the selected voltage setting at 8 to 12" (20 to 30cm).
The following data provides indicative distances at which the 275HVD will
detect a given voltage. Note that these tests were conducted in ideal test
conditions (unshielded single conductor, lab environment, sensor head
perpendicular to conductor) and are not fully representative of the work
site, which may have other voltages present (and which may influence the
overall results).
The distances should only be taken as indicative and not as electrical
specifications. Care should be taken when in presence of other conductors
which may also be detected by the 275HVD (see § 4.2). Measurements
are based upon a 90° angle (sensor head perpendicular to conductor).
