Chapter 7 Specifications
A-1 Introduction
Chapter 7 describes the complete specifications of the multimeter.
A-2 Technical Specifications
Specifications are based on the following conditions:
 One year calibration cycle.
 Operating temperature at 18 °C to 28 °C
 Accuracy is expressed as: ± (% of reading + % of range) after 30 minutes warm-up.
 Temperature Coefficient: add ± [0.1% × (the applicable accuracy)/°C] for 0 °C to 18 °C and
28 °C to 40 °C
 Relative Humidity: Up to 80% RH for 0 °C to 28 °C (75% RH for 10 M Ω and above ranges
for resistance measurement). Up to 70% RH for 28 °C to 40 °C
