3.4 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. Variations
may occur from unit to unit. As a general rule, in a clean environment, the
275HVD will trigger @ (45 to 65) % of the voltage range at 4 in/10 cm, and
detected the selected voltage setting at (8 to 12) in (20 to 30) cm.
The following data provides indicative distances at which the 275HVD will detect
a given voltage.
NOTE:
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).
