Dear all,

The computer that's been used to control my 34970A has crashed.

How can I retrieve the settings from all my data lines also the ones that are currently not open. I' using a 34901A 20-channel armature multiplexer, where 20 channels have a Gain and Offset. Now I can only read 2 of these channels.

 

So basically I ask how can I open the OFF channel using the 34970A Data Acquisition/switch unit?

 

Thanks in advance.

Hi,

If you want to find the configuration of each channel manually from the front panel, it is necessary for each channel that was OFF to put the type of measurement that was assigned to it before it was OFF with the help of the button MEASURE, for example:
I make the following configuration for channel 102, measure DC VOLTS, range 10V, 5½ digits, gain 2, offset 0.5V and say label ABC. By pressing the MEASURE button on the front panel, I can set a channel to OFF, from this moment, the Mx + B button becomes inactive for this channel, and I do not know anything about the config of this channel. If I press the button MEASURE again and I give it to DC VOLTS, the configuration for the range, the number of digits, the gain, the offset and the label reappears ... we see then the configuration of this channel . If you make a mistake on the type of measurement to be made for this channel that was OFF, for example you put AC VOLT instead of DC VOLT as it was at the original before the crash of your PC, you will lose the last configuration of this channel.
I have done various tests on my 34970A and 34901A successfully, so it is possible to find the configuration for each channel, provided that in the OFF state, it is switched to the correct measurement mode (TEMPERATURE ,DC VOLTS, AC VOLTS , ... I do not know if it's very clear, hoping that it can help you.
The ideal would be to use another PC with the software Benchlink datalogger3, using NEW BY UPLOAD, you would have all your configuration , even if the channels are OFF.
Benchlink datalogger3 config upload
