Ranges & Accuracies:
AC Converter: 61-772, 61-774 models are true rms sensing.
Accuracy: Accuracy is specified as +/-(a percentage of the reading + a fixed amount) at
23°C±5°C (73.4°F ± 9°F), less than 75% relative humidity.
Temperature Coefficient: 0.1 times the applicable accuracy specification per degree C
from 0°C to 18°C and 28°C to 50°C (32°F to 64°F and 82°F to 122°F)
*Accuracy stated for crest factor ≤ 3 at full scale and ≤ 6 at half scale
Input impedance: 400mV: >50MΩ; 4V: 10MΩ; 40V~ 1000V: 9.1MΩ
