Rob,
On the voltage of your PS, you will find that it will read the correct voltage at the load mentioned on the unit. For example it will be 12V @ 1 Amp load or whatever. No load will give a higher reading (resistance, inductance etc), and has nothing to do with the power input to a large degree.
I just measure my loads by hand using a small electronic scale. Are people really that busy they can't take 1/2 hour load their ammo???? I personally like to know my ammo is correct, and worry less about saving a few minutes.
Used a Harrell's for a while, and although pretty good, it had at least a 1 grain total variation (with 2208 powder - with 2205 it is awesome, but that doesnt help us target shooters much). Used it to load my small scale so did not save me any time - went back to using a measuring spoon.
RCBS Chargemaster HELP
Moderator: Mod
I had 2 RCBS units that did not work properly last year. Contacted NIOA (importers) and they changed the first one over for another one. The second one had the same problem as the first and NIOA had received quite a few complaints.
The problem was power supply related in that NIOA had sourced a local plug pack to provide the 9V DC required. The Chargemaster would not trickle feed and the fine motor control for part turn dispensing was in consistent.
My background is electrical/electronic so I connected the Chargemaster to a Variable Regulated Power Supply and gradually increased the voltage and the unit worked reliably at around 9.7V DC.
I did a little checking and discovered the recommended plug was a 9V DC at 1A unregulated unit. NIOA had sourced a regulated unit that precisely regulated the output voltage to 9V DC. An unregulated unit is supplied by RCBS and as Wood Rod pointed out they produce in excess of 12V DC lightly loaded.
The RCBS has its own internal voltage regulators built in but needs in excess of 9V DC. I went out and bought a Dick Smith regulated 2A 12 V DC plug pack and it works perfectly as would a 9V DC unregulated unit. I explained all this to NIOA and even RCBS had suggested to them the fault is power supply related.
The point of all this is that you should check your plug pack and see what NIOA have included in the box. My Chargemaster now works perfectly being connected to a 12V regulated unit.
The key pad problem may well be unrelated to power supply but its worth a check. I know the Chargemaster in the USA had a batch come out with faulty key pads.
Hope this helps a little bit in your fault finding on the unit you have recieved as I was in a similar situation.
