- 1CRO requires a special 'current mode' to measure current.
- 2CRO is inherently a voltage-measuring device responding to electrostatic deflection.✓
- 3CRO can measure current directly by changing internal connections.
- 4CRO has a built-in ammeter for direct current measurement.
Correct answer
CRO is inherently a voltage-measuring device responding to electrostatic deflection.
