sneezy

Hi Guy's, not sure if this is old hat information..

If anyone likes to fiddle I have stumbled on the calibration screens in my SJ Swallow (AKA Ripmax Prodigy).

Hold down the two outside buttons (Batt Type & Enter/Start/Stop keys) before you power up the charger. Keep holding for about 3 seconds and the cal screens come up.

BEFORE YOU DO ANYTHING. Toggle through the cal screens and write down the current cal numbers so you can back track to original.

So far I found I could trim the Input voltage reading, and the Discharge current settings. Input Volts was out a bit, current was VERY close to spot on anyway so I left it. I'd like to cal the Battery Voltage too but I'm buggered if I can figure that screen out, it seems to grab a battery voltage value (in A/D steps) as you enter the screen but will not adjust. I can't work out the Charge current calibration either but my unit is spot on anyway.

New cal values seem to store automatically when you get the 'finished' message.

If any other manic fiddlers out there find the answer to the last two adjustments please let me know.

PS> You need to know a little about whay your doing with this sort of thing or you'll end up burning your house down next time you charge a battery..... BE WARNED.

PSS> My Swallow works well as is and has been very good value for money, I'm just curious by nature.
