NLW-1000
The NLW-1000 wide-range logarithmic channel combines the functions of logarithmic counting and logarithmic current conversion to provide a continuous indication of reactor power from source level to full power. A remotely located pre-amplifier minimizes EMI and other sources of interference and adjustable discriminator and gain controls allow flexibility in channel calibration with existing detectors. A differentiator circuit provides continuous indication of rate of change of power, and self test functions can check count rate, current, period and high voltage. Provision is made for permissive operation by computer of all test functions.
