Re: 2019 DMM4050 Newest Firmware verification

It depends of whom is holding the soldering iron (experience).
It depends of getting at hand the exact component.
it depends if your soldering tools are made for such a job.

The software it is still there, the circuit does not boot up.

Re: 2019 DMM4050 Newest Firmware verification

InGuard IC memory corruption this translates: incoming measuring electrical parameter was greater than what input protection was capable to handle. This is the opposite condition of some else in the USA, he is trying to sell on eBay several used DMM4050 all electrocuted ones, due their LAN ports. He...

Re: 2019 DMM4050 Newest Firmware verification

I am all ears if you did discover any Bug.

And no, Tektronix has removed product support for this series, they do not deliver at user hands even a screw.

Re: 4-Wire Measurement Issues

4-Wire measurement of very low resistance this is prone to room temperature. DMM calibration for Zero Ohms (at input) this is made at 23C, In a cold room, zero Ohms CAL this gets negative Ohm values that Zero-Ohm math setting (offset compensation) cannot remove. For best results DUT temperature shou...

Re: Strange readings when measuring current.

For calibration comparisons if you do not own a proper manufactured short plug, any comparisons using DIY toys they are not considered as valid. This is a great way to protect yourself from questions. According my views, they are answers which I own nowadays, and they did not come from Google searc...

Hi David, The true hint and answer this is not noticeable or almost hidden at fine print of page 1-26 DMM4050 User manual.

I came also across this error and this tip above helped me to properly configure RS-232 to Bluetooth adapter 100m range. By permitting Flow control at paired modules the dmm stopped reporting such error. Everything now seems good at 9600 / Flow control RTS / 8 Bit , but when I am trying to use LabVI...

Re: DMM4050 remotely power control

This is a very interesting question , enabling Power Save mode remotely, extending display life-cycle. I think that if SignalExpress does not support such function, then possibly now one bothered to implement such a command into it firmware.

Re: keithly 2700 wrong voltage measurment

I would try to eliminate first all known issues.
a) Voltage spikes recorded due active auto-ranging.
b) Use of lower scan timing
c) Double check application bandwidth with measuring system specifications.
e) Health condition of individual scan card channel.
