Abstract: A meter is mounted on the wrist of the user with a suitable strap while the active or positive probe from the meter extends through a probe holder on the finger of the user. The probe lead is fairly short extending from the meter, through the probe holder to project beyond the index or pointing finger. Two forms of holding the probe to the finger are illustrated. The other probe to ground or neutral is longer and provided with a contact clip. The invention frees both hands of the user or at least all of the fingers except the one used to point the probe. With the invention the meter is more effectively and economically used.
