1. Minilog Series of Data Loggers ML1Digital Input (Rainfall and Flow) ML4204-20mA Input (Water Level) ML1-420Digital Input + 4-20mA Input + Temp + BV By : Steve Laurence Hydrological Services P/L

2. 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

3. 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 : ?Help STDisplay the status INCBucket Increment 0.2/01 (0.2mm bucket 01 event) DURDump Record (+ Dump Search) TTime DDate

4. 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 : ?Help RvHR River Height Ref (Offset) eg. 0.000 (4mA level) TxRTransducer Range eg. 30.000 TxITransducer Interval eg. 015/05 (15min log 5 sec warmup) WLWater Level now DURV Dump River Data (+ Dump search) TTime DDate

5. ML1-420 Minilog Internal 3.6V lithium OR 1.5V Alkaline Event logging of Rainfall + schedule logging of 4-20mA + TempC + Internal battery + External battery 400,000 Events / Measurements can be logged Requires an external 12V to power 4-20mA sensor Basic Commands : ? Help DUR Dump Rain DURV Dump River DUBVI Dump BattV Internal DUBVE Dump BattV External DUTMP Dump Temperature DUALL Dump All

6. WinComLog : More than a terminal program (Can also be an SDI-12 terminal to HS products) Can custom configure / program 72 buttons Setup scheduling / collection of data via dialup Plot / view collected data Download new firmware into products
