:::::::: My idea was something more like the 7904 (sorry for messing up the table). Then the sorting by year would make more sense: which was the most expensive device in that year. You could see how prices develop. Problem: I used the prices "2022 Dollar". this will be no use in a few years. AND its a lot of work. So, any guess how the table can be kept up to date with litle work? Greetings --[[User:Rubasch|Rubasch]] ([[User talk:Rubasch|talk]]) 07:37, 25 October 2023 (PDT)

== P6015 refill with oil ==
== AFG3021 ==


R114 has an absolute permittivity/dielectric constant of ≈2 as a liquid and near 1 as a gas.


As a substitude for the [[Media:R114 dielectric constant.pdf| R114]] I used [[Media:Shell-diala-s4-zx-i english.pdf| Shell-diala-s4-zx-i]] with a dielectric constant of 2.

The diala oil has a high break down voltage of 70 kV, is enviroment friendly, not corrosive and cheap.<br>
Drinking the oil is deadly, because it will creap into the lung!


Disasembling the probe body:
== TM500 Muli-Meter ==
* The resistor should never be touched
{| class="wikitable" style="text-align:center;"
* the resistor is plugged in and can be pulled out
|- style="font-weight:bold; background-color:#dae8fc;"
* The "golden cap" (resistor end cap) is screwed in. Use a big phillips screwdriver, put some cloth around it so no edges poke out, press it gently into the cap and turn. Be carefull!
! rowspan="2" | Name
 
! rowspan="2" | Digits
The Probe body is modified as follow:
! rowspan="2" style="text-align:left;" | True <br />RMS
* cleaned in ultrasonic bath (every printing on the device will disapear!)
! colspan="12" | Voltage Ranges [V]
* cleaned with isopropanol
! colspan="10" | Current Ranges [mA]
* airfree filled with oil
! rowspan="2" colspan="7" | Resistance ranges [k?]
 
! rowspan="2" | Temperature
Asembling the probe body:
! rowspan="2" | diode
* put everything together (gold cap, resistor)
! rowspan="2" | Rear <br />input
* hold the probe body upright
! rowspan="2" | Auto <br />Range
* put the sealing ring on top of the probe body
! rowspan="2" | Rear <br />Interface
* fill the probe body until the oil spills over the sealing ring
|- style="font-weight:bold;"
* put the probe togehter
| colspan="5" style="background-color:#dae8fc;" | DC
* clean up the mess
| colspan="5" style="background-color:#dae8fc;" | AC
 
| colspan="2" style="background-color:#dae8fc;" | dB
The compensation box is modified as follow:
| colspan="5" style="background-color:#dae8fc;" | DC
* C1: 47 pF ceramic/polystyrene capacitor parallel
| colspan="5" style="background-color:#dae8fc;" | AC
* C2: 220 pF ceramic/polystyrene capacitor parallel
|-
* C3: 100 pF polystyrene capacitor parallel
| style="text-align:left;" | DM501
 
| 4.5
Compensation:
| -
* follow the rules in the manual
| -
* the probe cable should be stretched out, because it has an importend influence on the first 100 ns
| 2
 
| 20
As a rule:
| 200
* if you can't tight C1/C2/C3 not as hard as you need for compensation: you need more capacity.
| 1,000
* if you can't loose C1/C2/C3 not as much as you need for compensation: you have too much capacity.

Using only ceramic capacitor seems to increase the ringing.
| 20
 
| 200
For soldering the capacitors into the compensation box, a hi-power soldering iron is needed as some pins have to be soldered directly to the chassis.

Test are done with a natronic [[Media:KHT 1000.pdf| KHT1000D]] probe calibrator.
: This is great, thanks!  I had a quick look and only found 20 liter cans as the smallest order unit, do you have a source for less (group purchase - Europe?)

::: It took me some time to figure out the right solution. At my company we bought 50 l. I use that. For someone living next to Berlin I can give a refill ;-) sending it to the US will be to expensive, I think. Giving away 1-2 l should be OK, so if some people get together, I can help. On the other hand, many other oils should be usefull, I just haven't tested them. Greetings, --[[User:Rubasch|Rubasch]] ([[User talk:Rubasch|talk]]) 05:26, 19 October 2023 (PDT)
