An instructional infographic for WarmlyYours snow melting mats and cables detailing the four-step megaohm meter testing process with technical diagrams of cable wiring and meter connections. Text overlay reads: "WarmlyYours: Be Connected. Be Warm. Be Radiant. Megaohm Reading Guide: Snow Melting Mats & Cables: You will need: Mega-Ohm: Snow Melting Mat/Cable: Before begining, verify circuit breaker is off and verify no power is present at relay supply line.: Megaohm Readings: Why? We do a Megaohms test to make sure no breaks or shorts have occurred that could affect the system's performance.: How? By following the four simple steps clearly indicated, to completve the readings that are required.: Step 1 - Setting the Megaohm Meter: Connect the black test lead to the measurement terminal labeled EARTH.: Connect the red test lead to the measurement terminal labeled LINE.: Set the function selector to 500V. Make sure that “B” indicator does not appear. If the indicator appears, please replace the batteries.: Step 2 - Taking the Readings: Working with electricity always presents a risk of electrical shock which can result in personal injury. Caution should be taken against such risk when operating the Megaohm Tester. Only a qualified electrician should operate the Megaohm Tester.: When taking the readings please ensure the following: • Your fingers are not touching any wires • The probes are firmly attached to the selected wires • There is no power in the circuit • The heating system is rolled out flat • The wires are not connected to the thermostat: Step 3 - Ground to Core Readings: Connect the probes to both the Core wire and the Ground wire at the START of the lead.: Take the reading as described in Step 3, then repeat this reading at the other core wire.: Ground: Black: Yellow or Red: RED/YELLOW-GROUND VALUE: BLACK-GROUND VALUE: Step 4 - Discharging the Element: When measuring an insulation resistance that contains a capacitance element, a charge proportional to the measurement voltage accumulates, and if undischarged, could lead to an electric shock accident.: End measurement without disconnecting the test leads from the object. Built-in discharge circuit automatically discharges the item. During discharging, the high-voltage warning lamp and high-voltage indicator will flash. They will go out when the voltage falls below approximately 30V.: IMPORTANT!: It is very important that for both CORE to GROUND readings you get a reading greater than 10 megaohms. IF NOT, you may have a short and should call for technical assistance at (800) 875-5285.: 24/7 Installation Support • (800) 875-5285 • www.WarmlyYours.com"
