Multichannel analyzer for parallel counting AMP-12 "Pulse-1A" (the analyzer) is a major structural element of the automated radiation monitoring system (ARMS) of NPPs. The analyzer is designed to create a new system or upgrade existing AKRB-03, 06,08 and their analogues.

The analyzer is intended for simultaneous reception of multiple channels of pulsesignals from the detection blocks and devices of ionizing radiation in the form of a sequence of statistically distributed pulses and measuring the counting rate of pulses; the simultaneous reception of multiple channels of analog signals the DC and voltagefrom the sensor with standardized output signals and convert them to physical quantities for each measuring channel.

• The analyzer is used in measuring information systems of radiation control for normal operating conditions  on NPPs.
• The analyzer is a means of measuring equipment in accordance with GOST 27452-87 and refers to the technical means of measuring information systems of radiation control for normal operating conditions  on NPPs.
• The analyzer refers to the technical means of automation of normal operation information systems.
• To influence the NPP safety analyzer is classified as normal operation.

Analyzer AMP-12 "Pulse-1A" passed state acceptance tests on DSTU 3400-2000, has a certificate of type approval № UA-MI/1-1437-2004 issued by the State Committee of Ukraine for technical regulation and consumer policy and submitted to the State Register of measuring instruments under the number U1807-03. TU U 33.2-19130157-009-203 consistent with the State Nuclear Regulatory Committee of Ukraine.
