USER GUIDE TB-9105 724 Plus Monitor Verification Tester Operation Instructions Made in the United States of America Features and Components A B C D Figure 1. SCS 770734 724 Plus Monitor Verification Tester E F Description G H The SCS 770734 724 Plus Monitor Verification Tester is used to perform periodic test limit verification of the SCS 770724 724 Plus Workstation Monitor. Verification may be accomplished without removing the monitor from its workstation. The Verification Tester is National Institute of Standards and Technology (NIST) traceable. Frequency of verification is based on the critical nature of the ESD susceptible items handled. SCS recommends annual calibration of workstation monitors Figure 2. 724 Plus Monitor Verification Tester features and the 724 Plus Monitor Verification Tester. The SCS and components 724 Plus Monitor Verification Tester meets ANSI/ESD S20.20 and Compliance Verification ESD TR53. A.

Rotary Switch: Selects the various pass and fail load values needed to verify the monitor s operator test circuit. E. Body Voltage Pushbutton: Loads the selected body voltage stimulus onto the Operator Test Lead when pressed. F. Body Voltage LED: Illuminates blue when the Body Voltage Pushbutton is pressed and voltage stimulus is applied onto the Operator Test Lead. G. Mat Fail Pushbutton: Simulates a MAT FAIL condition on the 724 Plus Workstation Monitor when pressed. H. Low Battery LED: Illuminates yellow when the battery power for the body voltage test circuit is low and needs to be replaced. Operation Verifying the Operator Resistance Circuit 1. Connect the 724 Plus Monitor Verification Tester s green ground lead to equipment ground. This may be done using the included Ground Plug Adapter or alligator clip. Figure 4.
