Notes:
a)In case of probe hanging in the air, the voltage inducted by the testing line may cause unstable readings
on the display screen, but that will not affect the accuracy of measurement.
b)The meter is a true rms responding meter. When the input leads are shorted together in the ac
functions, the Meter may display a residual reading between 1 and 30 counts. It will not attect stated
accuracy, but if using REL to offset this reading may produce a much larger constant error in later
measurements.
Notes: above accuracies can be guaranteed within 10%-100% of the full range.
