Input protection This instrument complies with
IEC61010-1 to protect the user
in the event of connection to
live systems. TDR2050 is rated
at 600 V CAT IV whilst all other
models are rated at 150 V CAT IV.
TDR2050 is specifically designed
to allow use on energised systems
up to the rated voltage. All other
models are designed for use on
de-energised systems and fused
leads must be used if the potential
voltage between terminals could
exceed 300 V
Output pulse Up to 20 volts peak to peak
into open circuit. Pulse widths
determined by range, cable and
model used.
Gain Set for each range with user
selectable steps (in Manual
operating mode)
Velocity factor Variable from 0.2 to 0.99 in steps
of 0.01
