Notes:
[1] Specifications apply for max resolution in each function, normal mode
[2] Assumes 4 hour warm-up period
[3] Input zero or offset null required whenever the temperature moves more than ±1 °C from the temperature at which the
previous null/zero was performed
[4] TCal = Ambient calibration temperature
[5] Integration time > 1 Power Line cycle
[6] Valid for signals >1 % Full Scale, Transfer Mode On. Signal must be DC coupled <40 Hz. Readings invalid with Transfer Mode
On and 1 Hz filter selected when using internal trigger mode
