Joulemeter, Student Digital

The Student Joulemeter is designed specifically for student use. The unit can measure energy from 1 joule to 999,999 joules, with accuracy of 3%, but 1% accuracy is typical. Power is by means of a 9V DC mains adaptor included.

Specification :

• Input voltage: 0 V to 15 V AC, or 0 V to 21 V DC (maximum).
• Maximum load current : 10 A AC/DC
• The stop button stops the timer and joulemeter, and disconnects the input power from the load.
• Circuitry : Microprocessor, combined with precision voltage multiplier.
• Built-in timing function, the start button starts timer and joulemeter together and at the same time starts powering up the load.
