Features :Small SizeLow CostRS232Easy to configure via asciiOnboard help (?)ML1 – 3.6V AA lithium battery

ML420 – 3.6V ½ AA lithium batteryML1-420 - 1.5V AA alkaline OR 3.6V AA lithium

ML1 Minilog• Event logging – each bucket tip creates an event in the data

memory• 100,000 events can be logged• Operates on internal lithium battery only• Basic Commands :

? HelpST Display the statusINC Bucket Increment 0.2/01 (0.2mm bucket 01 event)DUR Dump Record (+ Dump Search)T TimeD Date

ML420 Minilog• Timed logging – set a schedule of when you require

measurements to be taken – eg. Every 15 mins• 50,000 measurements can be logged• Requires external 12V battery to power 4-20mA Sensor• Basic Commands :

? HelpRvHR River Height Ref (Offset) eg. 0.000 (4mA level)TxR Transducer Range eg. 30.000TxI Transducer Interval eg. 015/05 (15min log 5 sec warmup)WL Water Level nowDURV Dump River Data (+ Dump search)T TimeD Date
