Controls & Indicators
The front-panel controls and indicators of the HZ 115 differential probe include an ON button, an OFF button, an attenuation switch with positions for x100 and x1000, and a low battery indication LED that flashes when the battery voltage is below 6V.
Installation / Setup
The installation and setup of the HZ 115 differential probe involve several key steps and precautions. Before using the probe, it is essential to read the safety precautions thoroughly. The probe must be used by qualified personnel and properly earthed by connecting it to an oscilloscope via the BNC output socket, ensuring the oscilloscope is also earthed. The maximum input voltage should not exceed 1500 V, and the probe should not be exposed to humidity or aggressive environments. The probe is supplied with a 9 V battery, which must be inserted before use. If the battery indicator LED flashes, the battery needs replacement. An external power supply can be used, disconnecting the internal battery. When connecting the probe, ensure the oscilloscope’s input impedance is 1 MΩ, and use safety leads for measurements up to 1500 V.
Operation
Before using the differential probe, ensure to read the precautionary measures thoroughly. Insert the supplied 9V battery into the battery compartment and connect it using the clip. If the battery indicator LED flashes, replace the battery as it indicates low voltage. To replace the battery, remove the screws on the rear face, open the probe, replace the battery, and reassemble the probe carefully without damaging components.
For external power supply, connect the probe to a suitable power source using the side socket, ensuring the power supply voltage is between 9 – 16 V DC. The internal battery will disconnect, and the automatic switch-off feature will not function.
When connecting the probe, ensure the oscilloscope input impedance is 1 MQ. Connect the probe output to the oscilloscope input using the coaxial lead and BNC socket. Avoid extending the cable significantly due to high impedance. For oscilloscopes with a 50Q input, note that the probe output voltage is halved, and consumption may increase. Use safety leads for reliable measurements up to +1500V DC + peak AC. Ensure any accessories used conform to safety standards.
