ELECTRICAL SPECIFICATIONS 
Accuracy is given as ± (% of reading + least significant digit) at 23 °C ±5 °C with relative humidity
lower than 80%. Accuracy is specified for a period of one year after calibration.
1. Temperature Coefficient is 0.1 x specified accuracy /  °C, < 18 °C (64.5 °F), > 28 °C (82.4 °F) 
2. AC Functionality: ACV and ACA specifications are AC coupled, True RMS; the accuracy for
