Notes for capacitance specifications:
1 Overload protection: 600 Vrms for short circuits with <0.3 A current.
2 The accuracy of for all ranges is specified based on a film capacitor or better, and after the Null function is used to
subtract the residual values (by opening the test leads).
3 The maximum display is 1200 counts.
