Instrument Description - Orbit Merret OM 502 User Manual

2. INSTRUMENT DESCRIPTION

2.1 DESCRIPTION
The OM 502 model series are 5 digit panel programmable instruments.
The instrument is based on 8-bit microcontroller with hight-rate 24-bit sigma-delta converter, which secures high accuracy,
stability and easy operation of the instrument.
