Notes for DC voltage specifications:
1 The accuracy of the 600 mV range is specified after the Null function is used to subtract the thermal effect (by shorting the
test leads).
2 For VZ
LOW
(low input impedance) measurements, autoranging is disabled and the multimeter’s range is set to 600 V in the
manual ranging mode.
