I successfully operated an electrical services business for 6 years as a self employed electrician to landlord clients. Offering step wise power operating capability of standard, power cabling at the lower power cable price tariff of installed circuits. In exchange for the safe guidance and instruction of surface cable runs within protective and affixed, conduit and trunking by the client, prior to my termination, test evaluation and commissioning of each circuit. Saving my time, increase in labor costs to the client and freeing up my time to take on multiple jobs in different stages of completion.
I guessed correctly, but I assume the equipment is subject to change. They are looking for a willingness to participate and have a go, even if you have no idea what you're doing, so don't worry if you're not an engineer! Be confident and look for clues, like units or gauges, to determine the type of sensor or tool.
