dvanced measurement mainly refers to the type of 
measurement which uses the result obtained by one of  
the basic measurements: ACV, DCV, ACI, DCI, 2/4W, 
Diode/Continuity, Frequency/Period, and Temperature.

Refresh Rate 
 
Background 
Refresh rate defines how frequently the GDM-8261 
captures and updates measurement data. A faster refresh 
rate yields a lower accuracy and resolution. A slower 
refresh rate yields a higher accuracy and resolution. 
Consider these tradeoffs when selecting the refresh rate. 
For DC measurements, the frequency of  the refresh rate 
depends on the rate settings (S, M, F) and the ADC speed 
settings (Accurate, Quick) (page 86 ). 
For AC measurements, the refresh rate (S, M, F) is 
directly tied to the AC bandwidth settings (page 80).
