Re: [volt-nuts] 3457A battery replacement at Keysight - not

You can buy litium batteries at conrad. They have axial wires and fit into allmost all hp , philips equipment. The length is half an aa cel. As the current is so low, only the leakage counts. I never understand why they charge so much for calibration. It is for equipment with a stability of 30 p

offset looking at the schematics on page 11.2-3 the bias should be adjusted by shorting the inputs of the amplifier and then a zero output. biasshorting the external input and measure the output of the amplifier i could not find the internal adjustments in the manual.  Met vriendelijke groeten Reg

It is stated that the ac calibration of a 3458 is so difficult. at least the equipment mentioned is so difficult to obtain. but look what you need. a hp signal generator 3325 where i have a pile of (any other good generator will do to), an other hp 3458 and 3 different thermocouples. very expens

[volt-nuts] 3458A resistance calibration

my 3458 was getting troubles with the calibration of the zero. As volts where no problem and ohm were pretty accurate, my conclusion was that there is basicly nothing wrong. the calibration stopped at the ohm-10. so it must be in the sense lines somewhere. on de dc print there where 2 big resist

[volt-nuts] How accurate is a fluke after 9 years

My Fluke 5700A calibrator was calibrated today after 9 years. It displays how much it deviated from the last calibration. For the both voltage references i got 0.0 ppm and for the internal 10k resistor -1.7 ppm. Only the amplifier for the 11-22 volt range drifted 1700 ppm for it depends on a vol
