Fault identification
Megger’s own built-in AutoFind mode allows for speedy
identification of faults. One press of the AutoFind key automatically
adjusts the range and gain, and positions the cursor to the first
major event on the cable. Press the AutoFind key again and the
cursor will jump to the next detected disturbance.
FindEnd function
TDR2050 also incorporates a FindEnd function, which allows the
user to automatically search the trace to identify the end of the
cable under test. This is useful in situations where a fast cable
length measurement is required.
For those who wish to maintain manual control, manual operation
allows full override access to refine the response for easy fault
identification.
Colour schemes
The very different light conditions that could be present when using
the TDR2050, combined with the limitations of eye conditions such
as colour blindness, makes the addition of set colour schemes in the
instrument extremely important.
TDR2010 and TDR2050 have 6 additional set colour schemes on
top of the Default and Outdoor schemes included on other Megger
TDRs. There are also 2 custom slots where the user can specify their
own scheme by setting up to 7 screen elements to their own choice
of colour.
Trace Tagging
TDR2010 and TDR2050 also incorporate a Trace Tagging feature
which allows the user to add a name to saved traces. This could be
the circuit ID, building name or any other identifying text the user
wishes to save with the trace.
A text string of up to 32 alphanumeric characters can be stored
against each trace and this can consist of upper case letters
including accents.
TraceXpert PC software
The TDR2000/3, TDR2010 and TDR2050 come complete with
the Megger TraceXpert software which gives full control over
downloading, reporting and uploading of saved trace results.
Designed around a database and programmed for ease of use and
simplicity, TraceXpert offers the ideal application for all your data
processing requirements.
Models
The TDR2000 series is available in 4 models.
TDR2000/3
A fully featured high resolution TDR with backlit colour display and
powered by Li-ion rechargeable battery batteries. This model comes
complete with 2 pairs of mini-clip Test Leads.
TDR2000/3P
The same as the TDR2000/3 but with Dual fused test leads replacing
the mini-clip leads
TDR2010
The same as the TDR2000/3 but with Trace Tagging and additional
Colour Scheme selection.
TDR2050
The same as TDR2010 but with the addition of 600 V CAT IV rating,
Step, DDG and FindEnd functions.
