OPERATING INSTRUCTIONS
Place the
B8572
instrument on table top or
flat surface, test button a if low battery
symbol appears , replace batteries.
Take 5lbs weights from case (use care)
Plug red/black test leads into test weights
Plug other end of leads into
B8572
Accessories:
B8565/20
(one 20’ test lead)
(For testing surface to ground on floors)
TESTING:
Types of testing as specified in ESD-S4.1
1.
Periodic testing on installed static safe
workstations.
2.
Qualification of workstation materials
3.
Performance of materials
4.
PERIODIC TESTING OF INSTALLED
PRODUCTS
Measure RTG (Resistance to Ground)
Remove items from surface to be tested
Remove ESD sensitive devices
Clip one end of test lead from B8572 to
grounded point (see fig 2.1)
Use one 5lb electrode on other test lead to
surface to be tested and push green button
TESTING FLOORS
Place one 5lb electrode of floor surface and with
B8565/20
20’
lead connect to known ground point.
(check with your facility staff)
.
Note:
ESD 7.1 is designed to measure floor materials
with resistance of 2.5 x 10
4
to 1.0 x 10
11
ohms.
Note:
ESD-S4.1 suggests that a static control surface
in the test range of 1 x 10
6
to 1.0 x 10
10
ohms is
acceptable.
QUALIFICATION OF INSTALLED
STATIC SAFE SURFACE RT
T
Measurements of resistance of Top to Top
and resistance point to point are the same.
Place both 5lb electrodes on surface to be tested.
Place no closer than 2” from edge of surface to be
tested.
Place no closer than 3” from any groundable point.
(snaps are a groundable point).
Place in the center of mat area it would be area
most worn. (about 10” apart)
For
RTG
Fig 2.1 place one lead with insulated plug
to groundable point.
REPORTING AND USING TEST RESULTS
Different standards have different requirements please
review the standards that you are testing too.
Per ESD 4.1
(work surfaces)
RTG maximum and minimum values
measured for resistance-to ground
RTG maximum and minimum values measured for
point-to-point resistance in ohms.
Per ESD 7.1
(floors)
RTG all values in ohms for resistance to ground
RTT all values in ohms for point-to-point resistance.
