GW Instek GDM-8245 - Frequency Measurement at Aca Range; Resistance; Capacitance

Introduction
15
refrain from using the 20A terminal for more than 15
seconds when measuring high current.
Crest Factor Range
3.0 at full scale.
The burden voltage is the same as the DC current.
When the input exceeds the full scale of the selected range, the display will
indicate over-range: ―—OL—―.
