I already own this unit. Are there any plans to upgrade the firmware to support higher capacitance measurement ranges? Currently it's limited to approximately a 10uF top-end range. We're doing measurements of electrolytic capacitors (e.g. 1,000 uF and larger) and were surprised to realize the limit on the high-end of this range. I don't know whether a circuitry modification would be required, but I'm hoping that the Agilent DMM product management team could look into this and see if there's any way to extend the measurement range with a firmware update. In comparing to the TEK DMM4050 or Fluke 8846A, for example, those units, which are comparably priced, have a very wide capacitance measurement range (up to 0.1F range in case of Fluke) which is more in line with what I would expect for a top of the line bench top DMM from Agilent. I am happy with this unit otherwise, but would love to see the capacitance range extended with a firmware update if possible. Thank you!
However, before the U1733c purchase, we realized that we could do "rough" testing of very high valued capacitors using the Agilent 34410A ohms scales (probably similar or identical to the 34411A ohms scales).
We outlined the procedure, based on the ohms scale constant current source, in a brief tech. note Link: http://www.gellerlabs.com/HiValCMsrmnts.htm | Using an Ohm Meter to Measure High Capacitance Values.
