[To all users]

  • Reconnecting cables between terminals of meter is no longer needed unlike traditional analog meters.
  • Unlikely to be damaged from wrong connection.
  • Avoid any human error that may occur when selecting measurement range.
  • Allows trial and errors freely in making various types of electric circuits.

[To teachers]

  • Battery change is automatically noticed on the display, so battery exhaustion before/during experiment became avoidable.
  • Automatic power-off function minimizing consumption of battery power.
  • Overload protection function.

[To students]

  • Better illustrate the similarity in the image of the meters written in circuit diagrams contained in textbooks.
  • Easily connect with electric circuit in accordance with the circuit diagrams thanks to the in-line type shape of the product.
  • No longer required to spend time for the troublesome measurement range selection as happens with multi-meters.
  • Easy to notice that an voltmeter displays results with plus (+) and minus (-) signs reaffirming the direction of electric current that flows in the circuit.
  • With two built-in cables extended from the corners on the meter’s main body, the shape of the meter better illustrates the image of detecting voltage values at any two points in a circuit.
  • Measurement range: ±25V
  • Automatically switchable display: 0.01V (0~±5.00V), 0.1V (±5.1V~±25.0V)
  • Size (body): 53 × 21 × 15mm, Whole length: ca 280mm
  • Battery: CR1220 x 1pcs

  • [EXPERIMENTS] Ohm’s Law Experiments: It is the purpose of this experiment guide to help learners study Ohm’s law through their experiments. As of the learning outcomes, they will induce the Ohm’s law out by themselves through the experiments in which they draw graphs of the relationship between voltage, current, and resistance.
