Multimeter 0.0.5 Jul 02 2002
______________________________________________________________________________
Multimeter
Multimeter is a simple command line application that reads values from
digital multimeter like Metex 4650CR or ME-11 using the serial interface.
It may work for similar DMMs too.
Feel free to download the current version multimeter-0.0.6.tar.gz

Changes:
0.0.1:
First attempt :)
0.0.2:
Thanks to Steve Atwell who added "-6" to make it work for Metex ME-11 DMM
(also sold by RadioShack as the model 22-805 DMM) too.
0.0.3:
Now works with 3-1/2 digit multimeters that are using the same line
protocol like Micronta 22-182. Thanks to Denny Fox for testing.
Arbitrary scaling of the output added.
0.0.4:
Compile problems with RH6.1 fixed.
0.0.5: Nov 17 2000
Thanks to Martin Kneppe who added "-9" for 9600 bps.
Now it works with the M4660A too.
0.0.6: Jun 16 2002
Thanks to Shane Bearham who added "-C" for CSV output format.
So far it has been reported to work with several DMMs.
maybe it works for you too. :)
./multimeter -h
Multimeter Version 0.0.6
Usage: ./multimeter [-N <samples>] [-n <print every Nth sample>]
[-T <sample_time>] [-t <print every t secs>] [-o <outfile>] [-v]
[-i <interface>] [-s {p|n|u|m|k|M|G|T|<N>}] [-6] [-m] [-c] [-l] [-h]
-N X: X values are to be read. (default 1)
-n X: print every Xth value. (default 1)
-T X: read values for X seconds.
-t X: print a value every X seconds.
-o X: output in file X instead of stdout.
-C X: output values in CSV format.
-i X: read from serial interface X (default /dev/ttyS1).
-s X: displays values scaled X={p|n|u|m|k|M|G|T|<Number>}
p .. 10^-12, n .. 10^-9, u .. 10^-6, m .. 10^-3
k .. 10^3, M .. 10^6, G .. 10^9, T .. 10^12
if X is a Number the unit will be marked with a '*'
-6 : use bit rate of 600bps (default 1200bps)
-9 : use bit rate of 9600bps (default 1200bps)
-m : mean value is calculated if there are more values.
-c : no send command will be sent before reading a
value from the multimeter (COMM button pressed).
-l : not time limit or sample limit (loop forever)
-v : display version number
-h : display this screen
Bugreports, patches, comments welcome ...
