lead (MP3) or a grounding spanner (both
supplied accessories). Either accessory
provides reference for a ground point. To
avoid possible shorting of other circuitry, use
the barrel insulator (supplied accessory) in
conjunction with the ground lead or grounding
spanner. Figure 3 is the probe in use with the
barrel insulator and a grounding spanner.
To install the barrel insulator, press on with the
wider end of the insulator to the probe body.
Press the grounding spanner on and twist a
few times to ensure it is fully mounted. When
used with only the insulating barrel and a
grounding spanner, the probe is in its
submlniature mode of operation and a very
short ground lead is obtained.
