[1]. Reading rate at 60-Hz and 50-Hz operating conditions, turning off auto zero, within a fixed range.
[2]. The number of display digits in the case of automatically displaying the number of digits. 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 sampling to the data transmission and display.
[4]. Read data by instructions.
[5]. Add 20μV to DCV; increase resistance by 20 mΩ. When DCA increases by 0.2μA, 100uA, 10mA range, the
range error is increased by 10 times.
[6]. Read stable data. The actual ADC sampling speed is faster than the stable speed.
[7]. External trigger or remote operation, using the default stable delay (automatic delay).
[8]. Use the default maximum value, set the delay to expire.
