Description The TM1700 series circuit breaker analyzers utilizes some of the ground breaking technology from the top of the line version TM1800. There are four models starting from PC-remote controlled to fully stand-alone. All models can be controlled from a computer using the well proven data management and analyzing software CABA Win. The robust design offers powerful technology that assists the user to achieve efficient and reliable circuit breaker testing. All inputs and outputs on the instrument are designed to withstand the challenging environment in high-voltage substations and industrial environments. Galvanically isolated inputs and outputs makes it possible to perform all relevant measurements in one test, eliminating the need for new setup and re-connections. The patented DualGround™ method makes the testing safe and time saving by keeping the circuit breaker grounded on both sides throughout the test. The timing measurement inputs are using a patented Active Interference Suppression algorithm to ensure correct timing and accurate PIR (Pre-Insertion Resistor) values even at high capacitively coupled interference currents

19. Brightness setting
▪ Indicates the position of the circuit breaker main contacts if the coil circuit is connected to the control section.
▪ Indicates the next operation of the circuit breaker. If Auto-detect breaker state is enabled in CABA Local or CABA Win, only possible sequences for the circuit breaker are selectable.
▪ Initiates the selected operation sequence and makes the measurement. Green “READY” LED must be lit before turning the rotary switch. The yellow “OPERATING” LED is lit as long as the sequence is performed.
