USER GUIDE TB-9012 724VK2 Verification Tester Operation Instructions Made in the United States of America The SCS 724VK2 Verification Tester can be used with the following items: Item Description 724 Workstation Monitor 724 W/O-PS Workstation Monitor, without Power Adapter 724K-WM10 Workstation Monitor Kit 724K-WM11 Workstation Monitor Kit Packaging 1 Verification Tester 1 Certificate of Calibration Operation Test Voltage 9 Volts and Resistance Selection 10 Megohms Set the 724 Workstation Monitor's test voltage to 9 volts and its resistance limit to 10 Megohms. Figure 1. SCS 724VK2 Verification Tester Description The SCS 724VK2 Verification Tester is used to perform periodic testing of the SCS 724 Workstation Monitor. The Verification Tester allows the customer to perform NIST traceable calibration verifying that the 724 Workstation Monitor is operating within tolerances. Using the 724VK2 takes only a few minutes and is designed to be used on the shop floor at the workstation to virtually eliminate downtime. Frequency of recalibration should be based on the critical nature of those ESD sensitive items handled and the risk of failure for the ESD protective equipment and materials. In general, SCS recommends that calibration be performed annually. 1. Insert the Verification Tester's stereo plug into the monitor's remote jack #1. 2. Select "1.5M LOW" with the Verification Tester's rotary switch. The monitor's green OK 1 LED should illuminate, and the yellow L LED should flash. The audible alarm should not sound. 3. Select "1.5M PASS" with the Verification Tester's rotary switch. The monitor's green OK 1 LED should illuminate. The audible alarm should not sound. 4. Select "10M PASS" with the Verification Tester's rotary switch. The monitor's green OK 1 LED should illuminate. The audible alarm should not sound. 5. Select "10M HIGH" with the Verification Tester's rotary switch. The monitor's red H LED should illuminate, and the audible alarm should sound continuously. 6. Repeat steps 1-5 for jack #2 on the remote. The audible alarm will chirp when jack #2 fails high.
