I'm not sure if this affects the OP, but it's worth considering that Tek AC/DC current probes like the P6042 don't do the DC measurement in the obvious open-loop way. Instead, the sense winding is

Maybe you can't afford another meter, but the old Simpson or Triplett units go for low prices at swap meets.? Occasionally an old timer will give you one.? They are very useful and even in this

application that the 80K-15 was made for<<<<< Obviously it's because the yellow one came in the box with the air cleaner.. hence the name *smile *. The red ones are called "High Voltage Probe for

I think we have discussed these before... they were not Polish... they were made by EMG in Hungary: http://www.radiomuseum.org/r/elektronik_oszcilloscope_tr_4658_155.html

Phil, I have a diode I believe to be a 152-0177-02 which has a bit tighter tolerance. The marking reads 140? It is used but unsoldered. They are precious. $10 plus postage from Texas. Jerry Massengale

Try the 152-0386-0x diode as well, it has 10mA.

If your 40A is at line frequency or SMPS frequencies like 20-100 kHz, it should be no problem - the linearity and accuracy will suffer, but there shouldn't be much power dissipation when occasionally

Hello-- It's possible that running a current probe over its rating would result in semipermanent magnetism of the core. You'd then need to demagnetize the core by running gradually-decreasing AC

I think we all know intuitively what happens if a voltage rating is exceeded on a probe or just in general: Bzzt and maybe poof! But what happens if you exceed the current rating of a P6042? It's

This scope model was in production for well over a decade. As mentioned several times in this forum, there is no direct way to determine production date from serial number. These records were never

Sorry yes its voltage. Its for testing the high voltage regulator in a 475. I cannot afford another meter or a $100 probe. The voltage divider idea may work.

ugly and wayyy overpriced - but interesting! english lettering.... Bernd _http://www.ebay.com/itm/OFFER-WIN-OSCILLOSCOPE-EMG-TYPE-TR-4658-works-like-

Looking for Tek 152-0177-01 tunnel diode (10mA and 4pf) for my 485. Also used in Tek products S53, 067-0587-01, 067-0580-00, 3T5, 3T6, 5S14N, 7D14, 7T11, 7T11A. Gold DO-17 top hat style. Including

It's the same size as the 80K-40, yellow instead of red, has the same 1 GOhm input impedance when used with a 10 MOhm input meter, but rated only for 15 KV instead of 40 KV. I don't really see why an

I'd never seen it called an Electronic Air Cleaner probe before. ;-) Mark

No surprise, electrostatics can go to some pretty high voltages. They can give you a nasty bite. settings online go to: http://groups.yahoo.com/group/TekScopes/join

I knew probes could be used for a lot of things, but this is a new one on me: <http://www.ebay.com/itm/FLUKE-80K-15-Electronic-Air-Cleaner-Probe-/310418595539> Mark

Hello RaymondI have a power supply for tds 420A.How much do you want to spend?If you send in your faulty I may be able to repair it or sell you one for parts.Thanks Jan Koria

Fluke 80K-6 high voltage probes are inexpensive used and good to 6 kilovolts. They are designed to be used with a 10 megohm input resistance multimeter which is standard. They only have 75 megohms of

Can you be more specific?? Are you measuring voltage? If so, an ordinary Simpson 260 or Triplett 630 will do, as long as it doesn't need to be very accurate. If you need precision you can cobble up a
