Product Description
Voltage sensor is used to measure the electric potential difference at both ends of the electrical equipment or circuits. Voltage sensor divides the voltage it collects to measure the electrical potential difference in DC circuit and low-voltage, low-frequency AC circuit.
Specification
Range: -30~30V
Accuracy: ±1%
Resolution: 0.02V
Input impedance: 2MΩ
Usage
Connect Voltage Sensor to any port in SenseDisc.
Connect red and black alligator clips to positive and negative poles in current sensor.
Parallel connect Voltage Sensor into circuit.
Voltage Sensor should be calibrated before using. Refer to calibration.
Typical experiment
- Series and parallel connection of resistor
- Solar power generation
- Measure the VA characteristic curve of small bulb
- LC oscillation
- Ohm's Law
Notes
- Voltage sensor should be parallel connected to the circuit during using
- Voltage sensor needs to be calibrated before using.
- The maximum voltage can be applied to sensor is 250V.
