USER GUIDE TB-9031 Workstation Monitor Checker Made in the Installation, Operation and Maintenance United States of America Features and Components Figure 1. SCS CTE701 Workstation Monitor Checker Description The SCS CTE701 Workstation Monitor Checker verifies the proper operation of the SCS WS Aware Workstation Monitor, SCS Ground Master Equipment Ground Monitor, SCS Iron Man Plus Workstation Monitor and SCS Ground Man Plus Ground Monitor. The Workstation Monitor Checker simulates resistance, impedance and voltage signals so that you can see whether the response of your monitors complies with your specifications. It meets the ANSI/ESD S20.20 requirements for compliance verification of continuous monitors. The Workstation Monitor Checker presents certain loads and signals to the monitor that simulate specic fi parameters of ground connections and wrist straps. The Workstation Monitor Checker is available in one model: Item Description Figure 2. Workstation Monitor Checker features and components CTE701 Workstation Monitor Checker, with 9V Alkaline Battery The Workstation Monitor Checker uses a 9V alkaline battery. Make sure that a fresh battery is installed prior Packaging to performing any test. If you are not planning to use 1 Workstation Monitor Checker your Workstation Monitor Checker for a long time, please 1 9V Alkaline Battery remove the battery from the device. 1 Ground Cable (banana to alligator clip) 1 3.5 mm Male to Male cable Basics For all tests make sure that: Monitor under test is properly grounded and is operational. Disconnect all wires from the monitor under test that go to the monitored grounds. Leave ground connection of the monitor connected to a known good ground.
