1. Every measuring point within measuring range can be shifted to zero with the AUTO ZERO
function.
2. Incandescent/fluorescent lamps
The LB-1000 series controller and sensor head are calibrated as a pair. Therefore, to satisfy
specifications, combine units having the same serial number.
Option
Extension cable
The sensor head cable can be extended up to 40 m.
