TDR2000/2 (CFL535F)
Cable Fault Locator
Interactive Help Screen
A full graphical help screen is available with keyboard
layout and individual key operation. At the press of a
button.
Trace Storage
15 internal trace memories provide for the storage and
recall of test results. The traces can be recalled to the
display for analysis or compared with an active display to
aid in fault location.
Alternatively the stored results can be downloaded to a
computer, over the RS232 port, using the TraceMaster
software and RS232 lead provided.
Trace Master PC Software
Trace Master provides download and upload facilities
between the TDR and a computer. Traces can be
individually selected, saved to a PC and annotated by the
user. Historical information can be reviewed on the PC or
recalled to the TDR for comparison with current
measurements. Trace-Master is the ideal tool for cable
documentation. Results can be printed from the computer
for inclusion in documents.
Power source
The TDR2000/2 can be supplied as a standard battery
powered unit or in a rechargeable version, as the
TDR2000/2RM or TDR2000/R. Fitted with a NiMH
rechargeable battery pack the TDR2000/2R and
TDR2000/RM are supplied with the charger as standard.
