Introduction
he Ludlum Model 16 Analyzer supplies the complete electronic
requirements for scintillation, proportional, or GM monitoring with
the added feature of a window discriminator circuit.
A two-position switch, marked
WIN IN
/
OUT
allows the instrument to
operate as a gross count ratemeter or as a single-channel analyzer. With the
WIN
switch in the
OUT
position, the discriminator level is controlled by the
THR
potentiometer, which is adjustable from 2 to 60 mV. In this mode, the
instrument performs as a gross count ratemeter. With the
WIN
switch in the
IN
position, the
WIN
potentiometer controls the high discriminator level. The
high discriminator level may be adjusted between the
THR
level and two
times the threshold level (not to exceed 60 mV). Other features include
AUD
ON
/
OFF
and fast/slow (
F
/
S
) meter response switches, meter
RESET
and high
voltage (
HV
) test buttons.
