04/24/13 17:43 536 1400 -750 6.2 6.3 Kraken was removed from SL1 and placed on SL2 to test up to full operating voltage on a burned in SL. SL2 averaged 1.2 microamps after 24 hours of full voltage on with the Kraken. moved Kraken back to SL1. Able to get voltage up much higher now, and current spiking does not occur quite as readily to high levels (e.g., 140 microamps with an average reading of 3 or less microamps). Current trip level is set to 200 microamps on all wires.
