the digital display. It is through this port that the meter is
connected to a PC.
Connecting to a PC
The TDR meter software comes with a gray PC interface
cable. This cable connects to the 9-pin serial port of your
computer and to the meter’s serial port. The meter’s con-
figuration can be modified by clicking on the Meter Set-
tings button (see Meter Settings, p. 12). The Com Port,
Meter Type, and Clear Meter Settings buttons are ex-
plained in the Main Toolbar section (p. 11).
Changing the batteries
The battery compartment is accessed by removing the me-
ter’s face plate. The meter runs on 4 AAA batteries.
When installing new batteries, note whether the bat-
teries immediately feel hot to the touch. The battery
has been short-circuited and should be replaced.
