A professional who tests electrical circuitry and measures temperature and depth level of materials in aluminum reduction pots. Respnsibilities include:

• Places contact rods of voltmeter against anode of reduction pot and against lining (cathode) of next pot on line to obtain voltage reading of pot circuit.
• Records meter reading, repeats test on next pot, and deducts reading from previous reading to determine any power loss.
• Repeats test on each succeeding pot to obtain and record power loss at each point along potline.
• Removes concrete sections of floor, using overhead hoist, to expose electrical circuits.
• Places prongs of millivoltmeter on ground and electrical connections to measure amount of positive and negative charges entering pot.
• Inspects electrical connections, firebrick lining, and wiring to detect damaged, worn, or broken parts, and notifies pot-room supervisor of discrepancies.
• Breaks hole in pot crust with crowbar, and inserts thermocouple to measure temperature of contents.
• Measures depth of contents, using measuring rod, and records temperature and depth on control form.
• Dips ladle into pot to remove sample of aluminum for laboratory analysis, and pours sample into mold.
• Records test readings, voltage loss, temperatures, and depth levels on master control form, and submits it to pot-room supervisor.
