Introduction:
This Quick Installation Guide is
for the installation
of the Tobi Wi-Z only.
See the Tobi Wi-Z Software
User Guide for instructions on programming and
calibrating the Tobi Wi-Z.
The installation of the Tobi will require a means to
calibrate the current on site. This requires a
computer located within 100 feet of the Tobi PI Wi-
Z with the TOBi™ Wi-Z software installed and the
Tobi Wi-Z USB coordinator.
Additionally, a means to verify charger amperage
output is needed to complete current calibration.
This can be accomplished by using an accurate
digital ammeter on the charger or a handheld amp
probe.

Installing the TOBi™ PI Wi-Z will require the following
tools:
Portable drill
5/32” drill bit- titanium coated preferred
1/2” drill bit
