What physical size is the original? I’d recently to source a small starter for a paint mixing machine; try RS 323-038 and associated trip.
Any overload trip needed? Remote control etc? Aux contacts?
I’d go to RS for any stuff like that. Not the cheapest, but good availability and support…
It’s the 1FBxxx number you want, Lawrence, and the procedure is in section 6.9 of document 599352430 on the TDS. Do you need a copy?
Whilst actual figures differ for each variety of bug, we can generalise by saying that sterility is created by
time x temperature
You pass a critical temperature for a hold time and… job done. Cycle time is the variable, in my experience.
Plenty ways to skin a cat tho:
60c + modern detergents, probably ? 30 mins at temp, maybe a three hour cycle.
121c/ 15psi in an autoclave? 15 mins at temp, again, 2-3 hrs cycle time (unless you’ve got some pretty fancy stuff going on heating and cooling- wise)
180c in a hot-air sterilising oven for a 1hr holding time. Oven can be preheated, so maybe 1 1/2hr cycle…
Or look at dairy, pasteurisation can be 71.7c for 15secs or 62.8c/ 30mins, sterilisation 104c/40min or 113c/15min, UHT 132.2c/ 1sec!…
You *sure* you’re on the uf range?
What does it read on the resistance range?
/nips out to car, brings in two different meters…On both of mine, 000= shortcircuit
?
Martin, you simply plug the cap into the socket on the meter (or apply the probes to it) and wait for the meter to work it’s magic. IIRC, the cap under test is put into an R-C or L-C circuit.
We’re talking about an actual capacitance range on the selector, not just watching it charge on the Ohms setting…
