General
Gear ratio	1/2

The Probix adapter HX0095 from Metrix is a specific accessory for SCOPIX oscilloscopes of models OX 9000 and OX 7000. It is designed for safe and precise voltage measurement in applications involving high voltages, particularly in power engineering. The adapter enables the connection of measurement accessories with Ø 4 mm plugs to the oscilloscope via a Probix connector. It is specifically designed for measuring voltages up to 1000 V and features an integrated voltage divider with a ratio of 1/2, reducing the measured voltage by half. This allows for the safe capture of voltages exceeding the maximum input range of the oscilloscope without damaging the device. The bandwidth of the adapter is less than 200 kHz, which is sufficient for measurements in power supply technology, as only low-frequency voltages are typically analyzed in this field. The adapter complies with the safety standard 1000 V CAT IV, making it suitable for measurements near power installations with high voltages between phases, for example, during multimeter measurements on distribution networks.

Applications

The adapter is primarily designed for measuring AC and DC voltages in power engineering, especially in installations where voltages exceeding 600 V occur between phases. It is used to safely measure voltage on high-voltage lines, transformers, or distribution switchgear. The CAT IV safety class ensures that the adapter is suitable for measurements near high-risk power sources, as encountered in industrial electrical engineering or during maintenance of power supply networks. Use in power engineering requires a high safety margin, which is guaranteed by the 1000 V CAT IV certification.

Functions and Equipment in Detail

The adapter features a Probix connector that is directly inserted into the oscilloscope, and an Ø 4 mm banana plug connector at the input, used for connecting measurement probes or other accessories. The integrated voltage division of 1/2 reduces the measured voltage by half, enabling the oscilloscope to process the voltage safely. The PROBIX system supports plug-and-play functionality, where the oscilloscope automatically detects the connected accessory and queries technical data such as division ratio and bandwidth. This enables error-free and rapid measurement without requiring manual settings by the user. The documentation included in the delivery contains technical information and instructions for use.

Technology Explained Simply

The integrated voltage divider in the adapter operates on the principle of a voltage divider, where the input voltage is divided across two resistors. With a division ratio of 1/2, the voltage is reduced by half, so the oscilloscope receives a voltage within its measurement range. The bandwidth of < 200 kHz means the adapter is suitable for frequencies up to 200 kHz, which is sufficient for measuring mains voltages (50/60 Hz) and low-frequency disturbances. The CAT IV 1000 V safety class guarantees suitability for measurements near high-risk power sources, as encountered in industrial electrical engineering or during maintenance of power supply networks. The insulated banana plugs at the input prevent short circuits and increase safety during handling.

Compatibility and Accessories

The adapter is exclusively designed for SCOPIX oscilloscopes of models OX 9000 and OX 7000. It uses the PROBIX system, which enables direct power supply and calibration of measurement probes via the oscilloscope. The accessory can be connected with BNC or standard cable connectors, depending on the available connector on the measuring device. Compatibility is limited to the specified oscilloscopes; other devices are not supported.

Mounting and Installation

Installation is performed by simply inserting the adapter into the Probix connector of the oscilloscope. The adapter features an Ø 4 mm banana plug connector, to which the measurement probe or another accessory is connected. The connection is tool-free, and the oscilloscope automatically recognizes the accessory. The documentation included in the delivery contains instructions for correct use. It is important that the measurement probe is correctly connected and safety regulations are observed, especially during measurements near high-voltage installations.

Advantages in Operation

The adapter provides safe and precise voltage measurement up to 1000 V, with the integrated voltage division reducing the load on the oscilloscope. The CAT IV safety class enables use in demanding environments, as encountered in power engineering. The plug-and-play system of the PROBIX system ensures quick and error-free commissioning, as the oscilloscope automatically recognizes technical data. Direct power supply and calibration via the oscilloscope increase measurement accuracy and reduce the number of required external devices. The use of insulated banana plugs increases safety during handling and prevents short circuits.
