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 MΩ and above ranges

for resistance measurement). Up to 70% RH for 28 °C to 40 °C
