Specifications
INTRODUCTION
This Section contains the specifications of the Dual Display Multimeter. These specifications assume:

A 1-year calibration cycle

An operating temperature of 18℃ to 28℃ (64.4℉~82.4℉)

One-hour warmup

Slow reading rate

Relative humidity not exceeding 70% (non_condensing)
Accuracy is expressed as ± (percentage of reading + digits).
