2.3 Connecting the CLAMP ON AC/DC SEN-
SOR
• To prevent damage to the meter, never connect or disconnect a
sensor while the power is on, or while the sensor is clamped
around a conductor.
• When disconnecting the output connector of the clamp-on sen-
sor from the 3290-10 sensor jack, be sure to hold it by the metal
part and pull it upward. Because the connectors lock, pulling or
twisting the cable can damage the cable.
