Dear Paul, Thank you for sharing your comments with me. I am back from a business trip and found lots of answers to my concerns. The instrument continues in the "green" with voltage indication within limits. You are right. After valuing the 5065a, I rather play with the cheap Rbs.
Take care and enjoy the weekend.
