Botron B8572 - Megohm Meter Manual

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

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

fig 2.1

TESTING FLOORS

• Place one 5lb electrode of floor surface and with B8565/20 20' lead connect to known ground point.

fig 2.2

(check with your facility staff)

Always clean mat surface with approved cleaner

Note: ESD 7.1 is designed to measure floor materials with resistance of 2.5 x 10⁴ to 1.0 x 10¹¹ ohms.
Note: ESD-S4.1 suggests that a static control surface in the test range of 1 x 10⁶ to 1.0 x 10¹⁰ 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.
• Voltage levels tested
• <10⁶ @ 10 volts
• >10⁶ @ 100 volts
• Note: Temperature & Humidity
• Test dates (work surfaces) quantity see ESD handbook TR 20.20 phg/ 5.3.1.3

EXAMPLE:
Reading (115.)= 1.15 x 10⁸
Reading (.096.)= 9.6 x 10⁴
Reading (.96)=.96 x 10⁵
Reading ( 6.3)= 6.3 x 10⁶
Reading (16.3)= 1.63 x 10⁷
Reading (6.13 G)= 6.13 x 10⁹
Reading (>20G)= 2 x 10¹⁰
Reading (100G)= 1 x 10¹¹ analog

(TR 20.20 pgh. 5.3.3.4)
Floor: Per (TR 20.20 pgh. 5.34.13) Testing and monitoring are required for performance.
Seating: ESD STM 12.1 and (TR 20.20 pgh. 5.3.5.3) recommend testing should be preformed. With a reading of 1 x10⁹ ohms.
Garments: A process of testing garments per ESD STM 2.1, point-to point and sleeve-to-sleeve resistance should be done. see (TR 20.20 pgh. 5.3.3.4)
