Hi! I Used the RS232 output from my DMM (Voltkraft, true RMS autorange) it's a nice feature, specially because this model has an Optocoupler, so the measured source is isolated from the computer, I use this one with a computer program in visual basic to plot the curve discharge/charge of a battery, very useful when you design a battery charge :-) But keep in mind that the readout speed is SLOOOOOW, about 1 read every 2 seconds, but for my requirements are far enough!. thisone sends a decimal value ever 2 seconds in 2400 baud N81 Oh another thing: Thinking about buy an Oscilloscope???, My humble opinion is that if you are a Pic programmer (or any processor) there is nothing more usefull that a DSO (Digital storage oscilloscope) I have the Tektronik TDS-220 dual trace 100 mhz 1 Gigasample, great machine, It's a little expensive but it worth every cent. Sometimes when I can't get a pic program works, and I have no idea of what is going on, just program one pin in the PIC so that in a given moment a UP or DOWN signal ocurrs and connect this to the TRIGGER input, and set the Scope for single shot. After that event, the oscilloscope will record all the information from the triger moment to ahead (depends on the timebase) later you can simply navigate the signals to see what hapened in this moment, this is an amazing capability that is impossible in any analog scope!. hope be helpfull with my comments. see you. byby Some hours ago you wrote: >Date: Mon, 4 Feb 2002 13:05:04 -0800 >From: Colin Constant >Subject: Re: [EE]:Oscilloscope >MIME-Version: 1.0 >Content-Type: text/plain; charset=us-ascii > >Has anyone tried one of those multimeters that have a PC interface?
