Can a multi meter measure a potential static discharge like between hands and laptop before I open cover and replace a battery? Like if I touch laptop and my hands with the each two probes of a multi meter, is it possible to read a DC potential voltage and determine if it is enough to cause a static discharge? Then we know that if we have to touch ground before touching laptop in the scenario of no static bracelet or failure of it.

    \$\begingroup\$ No the impedance is a few orders of magnitude too low at 1M . ESD protected FET buffers are needed in the GOhm range \$\endgroup\$ Feb 5, 2021 at 0:56

    \$\begingroup\$ But if you touch a 1M DMM between you and the case, any charge difference will decay to zero , just as touching the case will \$\endgroup\$ Feb 5, 2021 at 1:05

    \$\begingroup\$ Then we know that if we have to touch ground before touching laptop ... it makes no sense to be measuring anything ... it is easier to just ground yourself each time \$\endgroup\$
