Measurement accuracy, temp. drifts, max and min indications
All accuracies and min/max indications are referred to an ambient temp. range of 25°C ±5°C, rel. humidity
≤60% and scale ratio (electri-
cal/displayed scale) equal to 1. The conversion into °F is obtained acting on the electrical/displayed scale ratio.
