Easy, accurate, and time-saving ESD wrist strap and footwear tester with Digital Readout and proactive “Near-Fail” alert that tells you when your grounding devices are nearing failing levels.

What makes the PDT 800K unique is the proactive Near-Fail Indicator that alerts the user that the ESD grounding device under test (wrist strap or heel grounder) is nearing failure levels and should be changed soon if not right away. The results are visible with the digital screen on the tester's face. This helps prevents a worn device “passing” a test and failing in the field. This tester fully supports the “Compliance Verification Plan requirements as stated in the ANSI ESD S20.20. Simultaneously and independently test both feet and a wrist strap while filtering out human body noise.

The PDT series provides you a state-of-the-art fast, safe, and extremely simple tool to fully meet your daily ESD checking need. It further assists you to effectively enhance the performance of the EPA control and administration.

"Near-Fail" Proactive Testing
The "Near-Fail" indicator is a function to give a warning when the measured resistance is in the PASS range but is within 10% (default) safe range of the high or low limit. Besides the PASS LED, the corresponding LED of the high or low limit will be turned on to warn the user that the wrist-strap or the footwear is "Near-Fail". "Near-Fail" alert can be adjusted (increased or decreased) by Transforming Technologies - contact for more information.

Alarm Limit Adjustment:
The default upper and lower resistance limits fully meet the requirements of international standards such as ANSI/ESD S20.20-2007 or IEC61340-2007 – for wrist straps (35meg alarm) and for foot straps (100 Meg).  If you have an application that requires different test limits, the PDT series has dip switch controls.
