Setting the Line Voltage Selector Switch

Figure l-2. Setting the line Voltage Selector Switch

Before connecting the cable TV analyzer to the power source, you must set the rear-panel voltage selector switch correctly to adapt the cable TV analyzer to the power source. An improper selector switch setting can damage the cable TV analyzer when it is turned on.

Set the instrument’s rear-panel voltage selector switch to the line voltage range (115 V or 230 V) corresponding to the available ac voltage. See Figure l-2. Insert a small screwdriver or similar tool in the slot and slide the switch up or down so that the proper voltage label is visible.
