The output of a sensor device may deviate from the correct value due to loading effect. We can categorize two types of loading effect:Inter element loading- A given element in the system may modify the characteristics of the previous element.Process loading- The introduction of the sensing element into the process or system being measured causes the value of the measured variable to change.
Type youVOM has the higher loading effectr answer here...
please i need the answer

'Loading effect' applies to voltmeters, or to multimeters when set to measure voltage. It describes the change in a circuit's resistance when the resistance of the voltmeter is taken into account. It's effect is to cause the resulting measuredvoltage to be different from the actual voltage which would appear without the voltmeter connected. The loading effect is minimised by ensuring that the internal resistance of the voltmeter is significantly higher than the resistance of that part of the circuit to which it is connected. For general voltage measurement, this is usually the case anyway, but when measuring circuits which, themselves, have very high resistance care must be taken over the choice of voltmeter to be used.
loading of an ammeter in a circuit decreases the flow of current,so it has to be calculated to reduce expected errors in the operations
Kindle help me to answer What is valve point loading effect and its applcation
Type youVOM has the higher loading effectr answer here...
The higher the mismatch between the load impedance and source impedance, the higher the loading effect.
please i need the answer
Yes, you have to use an op-amp buffer to prevent the loading effect.

It does effect the measurement, but on an extremely low level. You could as well say it doesn't effect it.
