Accuracy – The accuracy of the meter at full scale is the accuracy of the setting of the reference voltage. Zero is
recalculated during each conversion cycle. The meaningful specification is linearity. In other words, the deviation from
correct reading for all inputs other than positive full scale and zero is defined as the linearity specification.
The LSD stability for 200 mV scale is defined as the range that the LSD will occupy 95% of the time.
Pin numbers refer to 24-pin PDIP.
