Function : This compact meter measures both Surface Resistivity and Resistance to Ground with a

test range from 10e3 to 10e12 ohms per square, with accuracy ± 10 %

Feature :The BHO-386 gives simple repeatable measurement of conductive, static dissipative and insulate surfaces by utilizing the ASTM standard D-257method of parallel bar sensing.

※ To measure surface resistivity, place the meter onto the surface that requires testing,

 press the red test button and hold. The LED that illuminates constantly is the decade measured.

    10e3Ω( 1K ohms)   ~ 10e5Ω (100K ohms)               Green LED [ conductive ]

  10e6Ω( 1Meg ohms) ~ 10e11Ω (100000 meg ohms)         Yellow LED [static dissipative]

  10e12Ω( 1000000 Meg ohms)                             Red LED [Insulation ]

   > 10e12Ω=INSULATIVE                                Red LED [ Insulation ]

   ※ Resistance to ground checking:

    Insert the ground cord into the ground socked. This isolates the test probe on the right side Of the meter ( the right side as the socket). Connect the alligator clip to your ground  Connection. Place the meter onto the surface to be tested, press and hold the test button

 The LED that remains illuminated is the decade measured. The measurement will be

Resistance to ground in ohms instead of ohms per square.
