What are the negative fluctuations that we expect with preferably the 34410A (or the 34401A) when we are in an open circuit or when a device is turned off for DC&AC Voltage&Current measurements?   I want to avoid the -0 issues with automated measurements, however I need to have a valid reason to put a negative value as a low limit.   Measurement… (Show more)

Hello - I have an Agilent 3458A unit (Malaysian built) and want to extend memory with option -001. Normally one needs to replace PAL device U102 with a modified logic content ...   On the Keysight website - there is a spare parts list for the 3458A that lists: - 03458A-88810         Programmed PAL-1819-0239 for 001          cost.: 26,71 euros… (Show more)

I recently had a battery leak on my U1242B. I cleaned up the corroded contacts the best I could. I also had one of the contacts on the back of the PCB corrode slightly where the battery cradle contacts touches the main board. There wasnt any other battery damage I could see. It was working fine until today.   Now I constantly get an AErr with… (Show more)

Could you please tell me the power adapter specifications of U1252B multimeter? Is it just a regular 24 VDC power adapter or is it a special charger?

Hello   I had to drill a hole in the wall in potential line of the power line. So I thought of the VSense function of my Keysight - U1282A to check if there are wires hidden in the wall where I want to drill.   But the V-Sense function is that sensible that its beeping when I move the meter near the wall. And I think its not that likely that the… (Show more)

Hi, I am using 34401A for 4-wire resistance measurement at the point of contact between gold-plated copper contacts. These contacts are just physically touching under a normal force which varies between 1 to 100g. I am using the default sampling rate of 34401A, 51/2 resolution and using LabVIEW to record data. I get values between 18-22mOhms but… (Show more)

Hello   I have a couple of U1272A devices, that I want to communitcate with using C code. I can see them on my device manager as a com ports.   My question is, where I can find a list of commands to get readings from the device?

Hi at all,     does anyone have detailed information about the Selftest of the L4534A Digitizer? How does the self test works? The overvoltage protection test is sometmes failed, if the unit is in warm conditions (powerd for several hours), in cold case, the test is okay. Where is the internal calibration source laoceted? Is there one for each… (Show more)

I there. I have a 3458A multimeter that we have repaired, after some errors showing on the display caused by the Dallas NVRAMs and Multislope Rundown and ADC Errors and so on. We switched the 2 dalas NVrams and the one thats has stored the calibration references data. Now we are trying to store again the reference data, folowing the 3458A… (Show more)
