Craig, Agilent has a User's manual for the counter, including options 010, 011, 020, 030 and 040. I have it downloaded. I also have a 93 page Installation &...
Hi Chaps, Apologies for the off topic post (though I'm still an avid user of hp stuff ;) Looking to clear out most of my workshop for reorganising for...
Hi Chuck, I recall hearing that some of the early 410C used the 2-01C as in the 410B and these run at 5v. Do you have any info on that? I also recall that...
Hello all, I've been following the thread. I have two 410B junkers on the shelf, if you are in the Long Island, NY area and have an interest, drop me a note. ...
Hello! Sorry for this off-topic but I need help with an eBay fraud. Seller is from Germany so a german person would be perfect. Please, contact me directly. ...
I know but the diodes themselves are not interchangeable in the 410C probe. So my question was how does one adjust the voltage in the 410C meter from 6v to 5v...
Hi Jerry, That presents a bit of a problem. In any mode other than AC, the probe has 6.3Vac on the filament. In AC, it has 6VDC on the filament. I think...

If you use a pair of diodes, back to back, then the drop in voltage will be less than you might think. Maximum volt drop across each diode will be at maximum...
Wait a second. Back to back means cathode to cathode or anode to anode, through which you would not get any ... But why not just a single resistor ? AW ... ...
a resistor would work fine just mount it securely ... From: Alexander Whiplash To: hp_agilent_equipment@yahoogroups.com Sent: Saturday, September 02,...
I have several manuals for sale for $5 each. I will mail them at anywhere at cost using UPS or USPS. All are original HP manuals, not copies or CDs. Contact me...
Excellent clean condition (possibly from lab environment or unused), with service manual. Has new memory NICAD, nice unit passes all selftests and functions...

Hi All, I have a HP 3336B that appears to hang after switch on. I have a gut feeling its a problem with the display/keyboard. I have a Signature analyzer and I...
Sorry John, If a device drops a voltage V and passes a current I, then the power dissipated, P = VI - no matter that it's a resistor or a diode. And...
Hello all. In my 410C, I have replaced the TO3 package power transistor with a TO3 three terminal variable voltage regulator chip. [ LM323K] This keeps things...
Hi Don, I do hope that you have some filtering upstream and downstream of the LM323. Otherwise you are asking the regulator to burst into oscillation at some...
73`s, Brian! I think I used 0.1uF multilayer ceramic capacitors as close as possible to the regulator itself. Had no trouble with any instability. It...

Several people have contacted me regarding these manuals. To minimize noise in this fine group I updated the list and put it on a web page with contact info:...
Hi John, I'ld like to see the physics text reference that says that the diode knee-point voltage times current flow can be considered a powerless loss. Brian. ...
It's a duty-cycle issue. He's referring to the fact that no current flows (hence no E*I loss) during a small portion of the waveform on either side of the...
Though the time that current is flowing through the diode is slightly shorter, it also has to be slightly higher than it would be in the resistor. This is ...
i think a properly mounted resistor is the solution ... From: Alexander Whiplash To: hp_agilent_equipment@yahoogroups.com Sent: Sunday, September 03,...
The filament is going to run cooler (lower RMS voltage/current) in both scenarios because in both cases you have added a series resistance. The heater is not...
Boy, We're really getting into wanker-based research, now. Can we go back to physics and electronics, please? Brian. [Non-text portions of this message have...
