[1]. Reading rate for 60 Hz and 50 Hz operating conditions, auto zero off, using a fixed range.
[2]. Digit mask set to Auto. If a fixed number of digits are selected, the number of displayed digits does
not change due to the test speed.
[3]. The average speed at which the ADC continuously samples data to the display.
[4]. Add 20 μV for DCV; add 20 mΩ for resistance. Add 0.2 uA + 10 times the above noise error range
for the 100 uA and 10 mA ranges for DC current.
