But anyway... >From the similar GPS 58503B manual: :DIAGnostic:LIFetime:COUNt? RESPONSE Returns the lifetime count, indicating the total powered-on time. Range of the integer is 0 to 4,294,967,296 with a resolution of 1. Each count represents three hours of operation. If I did the math right, that allows for about 490,000 years. Probably a bit more than necessary. The OP said, "started at life time 13917 and after 145Hrs it shows 13965" So that would be 13965 - 13917 = 48 x3 = 144 hrs 13965 x 3 = 41860 or about 4 3/4 years of on time.
