MODEL 09-0101: 1-POINT PEN PROBE
Resistance to Ground Measurement for Equipment
Introduction:
Resistance to ground measurements for equipment
determines if the material installed in the production
equipment has the ability to dissipate electrostatic to the
equipment ground. This test will measure resistance from
machine parts to the equipment chassis ground. It is
recommended to measure all machine p
arts within 12”
ESD sensitive product handling path per ANSI/ESDA
10.1, Automated Handlers.
For metal machine parts, an ohmmeter or the ohmmeter
function of a DVM can be used.
For coated or non-metallic machine parts, a megohm
meter with applied voltage of 10 volts or 100 volts as
appropriate can be used.
Procedures:
1. Connect the negative (-) terminal of your meter
(ohmmeter or megohmmeter) to the equipment
chassis ground.
2. Connect the negative (-) terminal of your meter
(ohmmeter or megohmmeter) to the one-point Pen
Probe.
Note
: When using the megohmmeter, the probe tip
may be energized up to 100 volts. Make sure that
sensitive products are not placed nearby the probe tip.
