EMIT Limit Comparator for Verifying Combo Tester X3 and SmartLog Pro 2 Test Limits - Desco 50424

A personnel tester is only as reliable as its test limits. With the EMIT 50424 limit comparator the ESD coordinator checks every 6 to 12 months that the Combo Tester X3 and SmartLog Pro 2 decide correctly at their set limits. The testers stay mounted on the factory floor, so there is no removal and no shipping.

Key benefits

• On-site verification: no downtime at the EPA entrance, the tester stays in place.
• Both test circuits: wrist strap via banana plug test leads, footwear via the foot plate cable.
• Targeted limit checks: rotary switch with settings just below and above 750 kilohms, 10 megohms and 35 megohms.
• Clear procedure: each setting must produce FAIL LOW, PASS or FAIL HIGH, so any drift shows up at once.
• Documented results: suitable as evidence in a compliance verification plan.

Applications

Periodic verification of wrist strap and footwear testers as part of compliance verification. The manufacturer advises basing the frequency on the sensitivity of the parts handled and calibrating the testers annually in general.
