NOTES:
1. 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.
2. The LSD stability for 200mV scale is defined as the range that the LSD will occupy 95% of the time.
3. Pin numbers refer to 24-pin DIP.
