Question 1
An analog multimeter is connected to measure a DC voltage, and the needle reads below zero. The most likely cause is:
◦
loss of potential.
◦
an incorrect meter setting.
◦
a damaged needle.
◦
reversed polarity.
Question 2
Auto ranging is a feature of a multimeter that:
◦
automatically indicates the polarity of DC measurements.
◦
automatically adjusts the meter's measuring circuits to the correct range.
◦
captures a reading and displays it from memory.
◦
responds to the effective heating valve of an AC waveform.
