About This Product
Experiments range from simple investigations into specific heat capacity to measuring the energy stored in LCR circuits. When measuring energy, an audible bleep, which can be switched off, marks each increment of the least significant digit, and a TTL pulse goes to the 4 mm sockets for external counters. When measuring power, a voltage sensor across the 0-10 V output can be used for data-logging. An instruction manual of experiments is included. The Joulemeter and Wattmeter is available for supply within India and for export to Mozambique, Jordan, Oman, Malaysia, Bahamas and Paraguay.
Frequently Asked Questions
Q1. Can the readings be data-logged?
Yes. When measuring power, a voltage sensor across the 0-10 V 4 mm socket output can be used for data-logging, and energy counts are output as TTL pulses for external counters.
