The net radiometer Q99258, which had been removed from site 2 on 13 Jun''02, was repaired and replaced in the spare sensor pool. The upper dome had been dimpled by heavy rain or hail. It was replaced with a new dome from the cache of net radiometer domes in the base.
Arrived at site 10 1/2mile west and 2 miles north of site #3, at 18:40 Obtained some dubious clods. Leveled the radiometer Departed at 19:10
Serializer and SlowAD were checked against a 'dial-a-volt' reference for consistency. Reference: 2.3995 (based on 4.5 digit dvm. output varied slightly between boards from about 2.3993 to 2.3998) A/D Values reported are nominal of what was observed. A/D Consistency: The 4 channels on each pmb-ad board were consistent within a few counts between the channels and between readings. Serializer Values: The measurement was that reported by EVE after scaling of the raw readings. These include the divide-by-2 cable used to scale the krypton voltage and represent mV. Note that for every unit, the nominal values shown had noise of about "1" mV total during the brief test. Serial Numbers: Dash numbers represent the residual reference voltage reading taken by Steve Oncley used in adjusting the output. For example"-07" represents 2.5007, "-93" represents 2.4993. PMB boards were tagged "A1" and "S1", etc. Sta s/nAD s/nSerial AD0 AD1 Serializer 1 A1-93 S1-07 23988 23987 2385 Note 1) 2 A2-95 S2-02 23976 23962 2390 3 A3- S3- 23987 23988 2390 4 A4-04 S4-96 23988 23987 2392 5 A5-88 S5-94 23985 23983 2391 6 A6-91 S6-09 23985 23981 2392 7 A7-06 S7-88 23984 23980 2392 8 A8-94 S8-99 23976 23976 2395 9 A9-97 S9-86 23985 23987 2391 Note 1) Station 1 was sitting in the cal-lab adjacent to the running co2 system. There was quite a bit of noise on the a/d counts while taking the readings inside to box there. The readings were roughly 23740/23770 and were changing by up to 100. The readings shown above were taken in a different box in a different location and the a/d counts were extremely consistent. I did not repeat the testing to determine whether the noise was endemic to station 1's box or not. Note that the readings for station 8 were taken in the same location.
