This meausures is mrem/hr and has the alarm set point on the gauge. There are multiple outputs of LOG out, Neutron, Gamma, Neutron + Gamma, and Beam Gate. There are Lamps, channel test, rate test, Averaging Time, and cal mode switches. I did not see anything happen when these were switched. The following is information I found on a newer model: "ALBATROSS" PULSE NEUTRON MONITOR The model 2080 Pulse Neutron Survey Meter is designed to measure either pulsed or steady state neutrons. The instrument may be operated as a fixed monitor or as a portable monitor using internal batteries. The microprocessor based instrument displays the dose rate on a digital alphanumeric display. The model 2080 uses the principal of nuclear capture to detect neutrons. The pulsed or steady state neutrons activate silver foil. The resultant beta is measured with a GM counter. A second GM counter subtracts the gamma background. This method of detection allows it to be used to measure very quick pulsed neutron fields. In addition the model 2080 has an alarm capability along with a failsafe relay contact closure for use as an area monitor. A built in horn and light are activated with the radiation level is exceeded. The front panel also has a green, yellow, and red lamp to signify the radiation level at a glance. Also included are a self test capability, front panel lockout, RS232 link and a digital calibration routine. The model 2080 offers all the capability, precision, and reliability that is expected from modern microprocessor based instruments. Self Test: Displays “FAIL†if no counts from either GM tube in presetable time. Usually set to 1 minute PSS: Personal Safety System: Relay opens on alarm, operated on watchdog principal (Albatross 4 pulse neutron and gamma detector was posted and is owned by: Kurt Christian) |
