3-2 85058B/EUse, Maintenance, and Care of the DevicesElectrostatic DischargeElectrostatic DischargeProtection against ESD (electrostatic discharge) is essential while connecting, inspecting, orcleaning connectors attached to a static-sensitive circuit (such as those found in test sets).Static electricity can build up on your body and can easily damage sensitive internal circuitelements when discharged. Static discharges too small to be felt can cause permanentdamage. Devices such as calibration components and devices under test (DUTs), can alsocarry an electrostatic charge. To prevent damage to the test set, components, and devices:• always wear a grounded wrist strap having a 1 M resistor in series with it when handlingcomponents and devices or when making connections to the test set.• always use a grounded, conductive table mat while making connections.• always wear a heel strap when working in an area with a conductive floor. If you areuncertain about the conductivity of your floor, wear a heel strap.• always ground yourself before you clean, inspect, or make a connection to a static-sensitivedevice or test port. You can, for example, grasp the grounded outer shell of the test port orcable connector briefly.• always ground the center conductor of a test cable before making a connection to theanalyzer test port or other static-sensitive device. This can be done as follows:1. Connect a short (from your calibration kit) to one end of the cable to short the centerconductor to the outer conductor.2. While wearing a grounded wrist strap, grasp the outer shell of the cable connector.3. Connect the other end of the cable to the test port.4. Remove the short from the cable.Refer to Chapter 6 for part numbers and instructions for ordering ESD protection devices.Figure 3-1 ESD Protection Setup
