1.0 EXECUTIVE 
SUMMARY 
1.1 O
VERVIEW
 
The RT30™ is a medium-range wireless AC voltage detector system, designed to use either direct non-contact 
voltage (NCV) measurement of an AC line, using the built-in cable clamp or an external clamp probe; or to 
detect the light output of a lamp connected to the tested line through a light-detecting resistor (LDR), in cases 
where the wiring is inaccessible.  Although the wireless operating range of the product is significant, power-
saving methods are used both to improve battery life, and to allow the RT30 to be used without the need for 
licensing as a radio transmitter.  Provisions have been made for the addition of other sensors in the future, using 
the external probe input.  The RT30 is targeted towards residential and commercial electricians and building 
wiring installers.

2.0 SCOPE 
The scope of this document is to define the basic functions and system level specifications of the RT30, 
including some aspects of future expansion. 
 
This specification is intended for use by members of the development team, and any development partners or 
consultants required by Extech.  Outside development efforts and duplication of the product shall be covered by 
separate business agreements for development and duplication/manufacturing, as required. 
 
Extech shall be responsible for maintaining and controlling document revisions for this specification.

MPLEMENTATION
 
This specification defines the high-level requirements of the product, including a detailed description of the user 
interface.  The electrical design of the RT30, including the firmware shall be developed by Extech.  The low-level 
design implementation of the mechanical parts shall be determined by Extech’s PRC development partner, 
CEM.   
 
Additional versions beyond the initial model may be required in the future.  The basic design of the RT30 shall 
allow for additional digital and analog probes to be attached, with minimal internal design changes; preferably, 
firmware-based.
