You want to use a digital. Faster reacting to fluctuations as with O2S and HO2s that constantly switch between hi and low readings ,and other millivolt circuits, and even the need to check resistance up to 40,000 ohms in some cases just to ensure components in a circuit are operating correctly to achieve the desired operation in the pcm, ecm, ecu or whatever terminology is applied.
An analog meter can test some electronic compartments, primarily by measuring voltage, current, or resistance. However, its effectiveness may be limited for complex electronic circuits, where digital multimeters or specialized testing equipment are often more suitable. Additionally, analog meters may not provide the precision needed for sensitive electronic components. Always ensure the meter is appropriately set for the specific type of measurement and circuit being tested.
Has hand instead of digital.
If your test meter is an analog type of meter there should be a zeroing screw on the meter face that is connected to the needle movement. Turn this screw to zero the meter. If the meter is a digital there should be a potentiometer, probably in the battery compartment that can be used to zero the display.

No, Pulse Code Modulation is a communication method used to carry digital data but is not part of any analog to digital conversion. PCM is often used to carry audio data as a digital stream and therefore is the encoding used as the signal is first converted to a digital format.

Pulse-code modulation (PCM) is a method used to digitally represent analog signals.
The main advantage of PCM (pulse code modulation) system is its robustness in transmitting and storing digital audio signals while maintaining high fidelity. PCM provides accurate representation of the original analog signal by sampling and quantizing it into binary code, making it less prone to distortion and noise compared to analog transmission methods.
in a digital meter you get a digital value of your measurement. but in analog meter you have to check the position of the pin along the scale and find out the value.

PCM is preferable because of better SNR characteristics.

An analog meter is a device which represents the value of a measurement by a point or similar indicator. A digital meter indicates the measure by actual displaying the number representing the value. For example, an analog thermometer shows a temperature.
