PC Interface
The meter is equipped with an RS-232 serial data port (located at the top of the meter next to the
probe input jack). This interface was designed to operate with the 407001 Extech software package
which includes two programs and the required meter to pc cable.

and view readings in real-time as they are taken (this software does not download the contents
of the meter’s memory to the PC)

contents of the meter’s memory to the PC
For streaming of data to a PC via the RS232 Output jack, the optional 407001-USB kit (RS232 to
USB cable and driver CD) along with the 407001 software (available free at www.extech.com) are
required.
