Subject: 4276A LCZ analyzer needs cal/adjustment,paper manual, standards.
Gentlemen (and Ladies),
I have a newly acquired 4276A LCZ analyzer in excellent mechanical shape and
a well-worn but functional 16047A test fixture.
I tried to do some serious capacitor measurements today of some 470uF
electrolytic caps, and after multiple open/short compensations, I am still
getting wrong values. I have a hand held C-meter and a Genrad bridge that
agree quite closely. An electrolytic that measures about 440uF on those two
units is measuring about 400 on the HP. I believe the HP is lying to me,
which makes it useless for what I need to do.
I have the download manual from the Agilent website, but the very long
fold-out troubleshooting charts and schematics are hopelessly chopped up in
the scan. I am hoping to locate a paper manual. Best price so far is $119
+ shipping :>(. Anybody have one for less?
I also need to buy/borrow/rent some 4-terminal pair calibration standards.
The manual calls for the following standard capacitors:
HP 16382A 10pF
HP 16383A 100pF
HP 16384A 1000pF
And the SHORT and OPEN from the HP 16074A standard resistor set.
Resistors from the 16074A standard resistor set are from 0.1 Ohm, 1 Ohm, 10
Ohm, 100 Ohm, 1kOhm, 10kOhm, 100 kOhm.
The resistors only have to be good to 20 kHz, so I believe that I can use
carefully measured metal film resistors for most of these values.
Anybody who can help with any of this, please let me know.
