NOTE: At 1 Gigohm high limit resistance, a dirty foot
plate could result in a false pass. Be sure to keep the

INSTALLING THE 19276 COMBO TESTER X3
1. Mount the tester at the desired location using the
four mounting holes located in the corners of the
yellow mounting plate.
2. Set the Dual Foot Plate below the tester.
3. Insert one end of the foot plate cord into the stereo
jack located at the bottom of the tester. Insert the
opposite end of the cord into the stereo jack located
at the back of the foot plate.
4. Use the guide located on the bottom of the foot
plate to route the cord out of the side. This will
prevent the foot plate cord from being accidentally
tripped and unplugged.

jack located at the bottom of the tester. Connect
ground cord’s ring terminal to equipment ground.
This connection will remove any static charge from
