Application
The list of the instrument applications includes:
 Timing measurement of up to 3 main contacts (1 break per phase) including pre-insertion resistors (if present in the circuit breaker) and auxiliary contact.
 Resistance measurement of the pre-insertion resistors (if present in the circuit breaker).
 Main contacts bounce time measurement.
 Evaluation of synchronization between the circuit breaker poles.
 A measurement and graphical display of the coil currents.
 Coil control (built-in) for actuation of circuit breaker’s OPEN and CLOSE coil.
 Evaluating the state of the substation’s battery (or other types of analog signals that may be relevant)
by presenting the voltage value numerically and graphically.

DV-Win software
DV-Win software provides acquisition and analysis of the test results. Graphical presentation of a variety of measurements and timing test results uses cursors and powerful zoom functions for detailed analysis. Colors,
grids, scales and positioning of the test data are all controlled by the user.
DV-Win supports an automatic unit conversion (e.g. cycles to seconds or mm to inches). The test records can be exported in .cath file format for further analysis.

 Downloading the test results from the CAT-H to PC
 Acquisition and analysis of the test results
 The test results can be viewed, edited, saved, printed and exported
 Viewing and overlaying several graphs, for an easy test result comparison
 Selecting the measurement points and intervals using the two cursors
 Zoom and pan graph feature
 Customized configuration of the test result graphs
