Using Compass LV
When using Compass LV, it should always be mounted under the brim of a hard hat in the center of the user’s face.
Positioning is very important:
- Off-center placement can cause errors in direction and proximity detecton.
- Direct contact with the human body will decrease the unit’s sensitivity.
- If the unit’s lights do not stay within the user’s field of vision, they could miss potentially lifesaving alerts.
When detecting low voltage (below 600V), Compass LV can be detached from the user’s hard hat and held between thumb and forefinger (refer to illustrations). Holding Compass LV differently than illustrated may reduce accuracy of directional notifications and proximity alerts.
Detection Distance and Sensitivity
Compass LV provides audio and visual alerts when you approach a source of live voltage. You can adjust the distance that will first trigger an alert by changing the unit’s sensitivity settings (see “Master Sensitivity Settings” in the Compass LV User Guide)
The following illustrations represent the initial detection distance for each pre-set sensitivity (Low, Medium, and High) when approaching a 120V or 480V energized source. The voltage source was a 3″ copper wire protruding out of a standard outlet box 16″ off the ground.
COMPASS LV WILL DETECT VOLTAGES OVER 2.4 KV, BUT SENSOR SATURATION MAY CAUSE REDUCED ACCURACY OF DIRECTIONAL AND PROXIMITY NOTIFICATIONS.
DETECTION DISTANCES WERE CALCULATED WITH A HANDHELD COMPASS LV AND MAY BE SLIGHTLY REDUCED BY HARD HAT USE.
DO NOT RELY ON USING COMPASS AS A HANDHELD DEVICE WHEN DETECTING THREATS OVER 2.4 KV.
