Specifications
Introduction
Appendix A contains the specifications of the Fluke 45 Dual Display Multimeter.
These specifications assume:
• A 1-year calibration cycle
• An operating temperature of 18 °C to 28 °C (64.4 °F to 82.4 °F)
• Relative humidity not exceeding 90 % (non-condensing) (70 % for 1,000 kΩ
range
Accuracy is expressed as +(percentage of reading + digits).
