Features :
 Small Size
 Low Cost
 RS232
 Easy to configure via ascii
 Onboard help (?)
 ML1 – 3.6V AA lithium battery
ML420 – 3.6V ½ AA lithium battery
ML1-420 - 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 :

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 :
?

RvHR River Height Ref (Offset) eg. 0.000 (4mA level)
TxR Transducer Range eg. 30.000
TxI Transducer Interval eg. 015/05 (15min log 5 sec warmup)
WL Water Level now
