Calibration
The Constant Monitors are calibrated to standards
traceable to NIST. Frequency of recalibratrion 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.
Use the SCS TMTOOL Verification Tester to perform
periodic testing (once every 6-12 months) of the
Constant Monitors. The Verification Tester can be
used on the shop floor within a few minutes virtually
eliminating downtime, verifying that the monitor is
operating within tolerances.
