DMM MAS345 via RS232 communication


Recommended Posts

Can someone help me to create a .VI to aquire data from a DMM MAS345 through a RS232 connection(i'm a beginer in labview)?Here are some initial data where to start:

RS232C Interface protocol

3-1. MAS34X series

Mode : 600,n,7,2

Format : Ascii Code

Total : 14 bytes

Whenever any one byte received from P/C, output 14 bytes.

BYTE 1-2 : MEASURING MODE (ex;DC,AC,OH,CA,TE...)

BYTE 4 : SIGN(-)

BYTE 5-9 : Decimal point and value

Current measurement value(ex;10.00, OL.,3.999)

BYTE 10-13 : Unit (ex; mV,A,KOHM,nF...)

BYTE 14 : Carriage Return

Note : Interval time over 1 second is required for stable

measuring data from the meter.

I also know that ASCII code for data is D
