Installation / Setup
The installation and setup of the differential probe for oscilloscopes include the following highlights:
1. Safety Precautions: The probe must be used by qualified personnel, and it is essential to earth the probe by connecting it to the oscilloscope using the BNC output socket and auxiliary grounding terminal. The oscilloscope must also be connected to earth. Do not disconnect the probe from the oscilloscope until the test leads are disconnected. Use only high-quality accessories that conform to safety standards.
2. Battery Installation: Before first use, insert the supplied AA batteries into the battery compartment, ensuring proper polarity. Do not connect input leads to the item being tested during battery insertion or replacement.
3. External Power Supply: The probe can be connected to an external 6 V DC power supply, which disconnects the internal batteries. The power supply must conform to safety standards.
4. Connecting the Probe: Connect the probe’s output to the oscilloscope’s input using the coaxial lead. The oscilloscope’s input impedance should be 1 MΩ. Avoid extending the cable significantly in high impedance connections.
5. Attenuation Choice: The probe offers x10 and x100 attenuation factors, selectable via a switch.
6. Usage Procedure: Ensure the oscilloscope is properly earthed, connect the probe, adjust the oscilloscope’s vertical sensitivity, select the attenuation factor, switch the probe on, and connect the test leads to the item being tested.
7. Maintenance: Clean the case with a damp cloth if necessary, ensuring no moisture enters the device. Do not attempt repairs; send the device to the distributor if needed.
Operation
The basic usage steps for operating the differential probe include:
1. Before using the probe, read the safety precautions thoroughly.
2. Insert or replace the batteries by removing the protective rubber boot and sliding back the battery cover. Ensure proper polarity when inserting new batteries.
3. Alternatively, connect the probe to an external 6 V DC power supply using the socket on the side. Ensure the power supply conforms to safety standards.
4. Connect the probe to the oscilloscope using the coaxial lead inserted into the BNC socket. The oscilloscope’s input impedance should be 1 MΩ.
5. Switch the probe on by sliding the power switch to the “1” position, indicated by the LED lamp lighting up. Switch off by sliding to the “0” position.
6. Choose the attenuation factor (x10 or x100) using the selector switch. For x10, the input voltage is equal to the oscilloscope voltage x10; for x100, it is x100.
7. Ensure the oscilloscope is properly earthed, connect the probe, adjust vertical sensitivity, select attenuation, and connect test leads to the item to be tested.

Safety & Warnings
The probe must only be used by qualified personnel. It should be earthed by connecting it to the oscilloscope, ensuring the oscilloscope is also earthed. The probe should not be disconnected from the oscilloscope until after the test leads are disconnected. Only use high-quality accessories that conform to safety standards. Never open the probe while input leads are connected and do not exceed the maximum input voltage. The probe should not be exposed to humidity, steam, or aggressive/explosive environments. Keep the probe and its components clean and dry. Do not use the probe if it is suspected to be faulty. The mains power supply must conform to current standards. If not in use for a long period, remove the batteries to prevent damage.
