1. Relative to calibration standards.
2. Within one hour of dc zero, using offset control.
3. When offset control is not used the number of counts are 50, 70, 90 and 90 for 24 hours, 90 day, 1
year, and 2 year respectively.
4. When offset control is not used the number of counts are 5, 7, 9 for 24 hours, 90 day, 1 year, and 2
year respectively.
MEDIUM AND FAST RATES: ................In medium rate, add 3 counts (20 counts on 20 mV Range) to
number of counts. In fast rate, use 2 (4½ digit mode) counts
(30 counts on 20 mV range) for the number of counts
(30 counts on 20 mV range) for the number of counts
