Input Instantaneous value range: -9999~9999 radix point position could be set Cumulation value range: 0~99999999 radix point position could be set Resolution: 1/20000 Instantaneous valueInput signal type: pulse Pulse: 0.1~150 KHzBasic error: Less than±0.2%F.SControlling period of measuring: 0.2 second RecordRecord capacity:4MBRecord interval:1second~59 minutes59seconds could beselected.Cycle record or full record suspends could be chose. Record time:The computational formula between the record time and record interval:Record days=record capacity×record interval/24×360072 hours is the shortest time record; 29 years is the longest time record.Record content: instantaneous valueAlarm Alarm output: instantaneous flow Hi-lo limited alarm mode and cumulative volume preset output.OC door output,voltage less than 30V,current less than 50mA TransmitIsolated output4mA~20mA,0mA~10mA,0mA~20mA DC current output, could be selected by setting . The resistivity load is more than 600Ω. DC current output, select through setting. Load capacity should larger than 600ΩOutput resolution:1/4000,error less than±0.5% F.SCommunication connection IsolatedRS485 domain communicationInstrument address: 0~99 ,which could be set Communication rate: 24004800960019200 could be selected by setting. It is should be note when book the meter<2400 There is a put-off when the meter reply the commend from the computer. The instrument will send the relevant delay reply of the data when it received the order from the computer:Be based on the "#" as the order of the rule, the delay reply <500μs ;other delay reply 100ms . Auxiliary test software, and supply the Technical Support Power supply of the transmitterNormal power supplypower supply  for the transmitter.  The error of Output value is±5% than the standard value. The load is > 50mAPower supply24V DC± power consumption:less than 10VADimensionOutline dimension: 96×96×103mm( height×width×depth)Slot dimension for Installation :91×91 mm(height×width)InstallationInstallation : Jam-in
