Installation
Check for a Good Ground
After installing the ground kits, use a multimeter to confirm that the seat and printer are both grounded
properly.
Follow these steps to verify a good ground connection:
1. Turn OFF all accessories, including the dome light, to prevent other currents from distorting the
reading.
2. Take a multimeter and measure the resistance between the brackets the two ground strap bolts are
fastened to. Find a clean spot on the brackets without paint to use as contact points. Other bolts
on the brackets are often suitable.
Turn Off Accessories
If the multimeter reads “MΩ” or “KΩ”, typically, one of the
accessories is still on
·
If the resistance is less than 3Ω, the system is grounded adequately.
· If the resistance is still greater than 3Ω, check for proper metal to metal contact on both ends of
the ground strap. Clean any paint, dirt, or oxidation that may block the grounding point. If the
resistance remains above 3Ω, attach the ground strap to a different ground point. Repeat the
process until the ground resistance is below 3Ω.
Verify good contact
If operator receives a ESD discharge when leaving the seat, the
ground strap is not installed correctly.
