These are the instructions RCBS sent to adjust the PID.

Instructions from Rcbs for Pro Melt 2

 

[Dimner]

Nice instructions! Did you get that from RCBS?

I tried to backtrack to the mfg of the PID and it looks like they no longer make the exact same model, or at least updated it since RCBS started using it.

Here is my guess at the closest thing they make now:

CHB102 Digital Display PID Intelligent Temperature Controller

General description : CHB series intelligent (temperature) display regulator adopts 8-bit single-chip high reliability, a variety of sensors freely input, and it adopts a wide range of switching power supply. The product’s performance indicators, input style, control function and the insta...

so now, I'm off looking for the CHB102 manual.

Yes, rcbs emailed them to me.

I decided on a route to take. Not sure why it had not occured to me sooner.

Picked up a long probe thermocouple on amazon for $18 bucks. I'm just going to disconnect the OEM thermocouple from the back of the PID and connect this one and attach it to the top of the pot. This will give me a temperature measurement deep in the alloy. The OEM thermocouple can just sit there where it was installed until if/when there is a work around from RCBS.

Which one did you get from Amazon?

Went with this one...

800 degrees Centigrade! Is that overkill or what?
With that external thermocouple you could use that PID to operate other devices, e.g. a toaster oven etc.

Well . . . That's only 1472 degrees Fahrenheit. However I highly recommend NOT using your aluminum molds since aluminum melts at 1221 Fahrenheit and you may run into lengthy waits between pours. You may also run into problems melting the mold halves together and never opening them again making it quite difficult to drop bullets.

I only bought the 800 because it had a long probe to fit in the alloy and the probe is threaded so you can mount it on a bracket.

The 700c version has a 1mm probe

The 500c version has a thin probe with no threading for a bracket mount

I need one of those for my pottery kiln so I can case harden and heat treat steel.

You aren't likely to burn it up with your relatively mild lead casting temps either.

Have you installed it yet?

 

[Dimner]

Not yet. Its sitting here on my desk.. Have not been down to cast in a while. On a PC baking and test shooting binge. Probably won't get to it for a couple weeks.
