TECHNICAL BULLETIN TB-7560 Monitor Calibration Unit Made in the Installation, Operation and Maintenance United States of America Calibration Test Procedures The Monitor Calibration Unit was specifically designed for use in calibration of Vermason brand equipment. The following procedures will not cover adjustment of the test equipment. For detailed information regarding adjustment of specific Vermason brand testers, contact our Customer Service Department at 0044 (0) 1462 672005. 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, we recommend that calibration be performed annually. Figure 1.

Connect the Calibration Units GROUND test lead to a ground point. 2. Insert a wrist cord into the satellites operator jack and snap it to the parking station. This will enable the audible alarm circuit needed for calbration verfication. 3. Connect the included stacking snap to the Calibration Units MAT test lead. Disconnect the satellite from its mat connection and re-install it to the Calibration Units stacking snap. NOTE: The stacking snap must be isolated from the grounded mat. Figure 4.
