574 POCKET TESTER WITH 45 RANGES

Small sized instrument for measuremed of AC and DC tension and current, resistance, capacitance. Moving coil meter with 40A sensitive.2500 om.gif (127 byte) internal resistance, class 1.5. Dial with four colour scales and anti-parallax mirror.

 

Ranges:

Tension in DC: from 0.1 V a 1500 V full scale in 8 ranges

Tension in AC: from 7.5 V full scale to 2500 V full scale in 6 ranges

Current in DC: from 50 A full scale to 2.5 A full scale in 6 ranges

Current AC: from 2.5 mA full scale to 12.5 A full scale in 5 ranges

Resistance: 2kom.gif (127 byte)  - 20 kom.gif (127 byte)  - 200 kom.gif (127 byte)  - 2 Mom.gif (127 byte) .

 

Immersion heather - Joule's Law (from Experiment instruction)

.....Pour 300 ml petroleum into each of the 2 vessels and place a coil in each, connecting them in series.

Note the initial temperature of each versel, and allow current to flow for approximately 5 minutes.

Stir and read the final temperature of the liquid in each of the vessels.Observe that the temperature of the liquid in the vessel with the 10 om.gif (127 byte) resistance has increased by twice that of the vessel with the 5 om.gif (127 byte)  resistance.......
