Common attribute: refresh rate
Background
Refresh rate defines how frequently GDM-8200 series
captures and updates the measurement data. Faster
refresh rate yields better accuracy but lower resolution.
Slower refresh rate yields lower accuracy but higher
resolution. Consider these trade-offs when selecting the
refresh rate.
Range S
5 ½ digits
M
4 ½ digits
F
3 ½ digits
Selection step
1.
Press the Shift key followed by
