Tonghui TH2830 LRC meter serial port, HOW ? BRAKE THRU, ALIVE
oz2cpu:
little video to explain where we are:
https://youtu.be/pi1_lMlIY_Q
as far as i tell by this experiment
only pin 2 and 3 are used in the serial connector..
so no hardware handshaking is used at all

end of line must be 10 (also called LF)
use Tera Term to see it is working
NO HARDWARE HANDSHAKE USED.
talk only, dont work,
so far no luck figuring out how to read measurement values,
manual is very hard to understand.. will update if/when we solve that.

QUESTION :
can you show an example, how to read the measurement values of capacity and impedance?
or whatever the mode of measurement that is selected..
I do not understand:
the page command
the display command
the line command
the display:line command
none of it seems to work, all i get is a beep,
need examples in the manual that works..
also the listed page examples listed is not what the instrument reports
it seems like i need to select a screen page, and on that page, select the correct line,
and then read out that line, no luck..
what i have working :
the frequency command works
frequency?
reports the current frequency
frequency 100
sets the frequency to 100hz
and so on..
Martin72:
Tomorrow our ST2830 should arrive ( after over 5 weeks...) at last.
If I get the time I could try something on it.
How did you transfer the commands to your lcr, via the commandline from HKJs Testcontroller software?
