Safety Information

Prevent personal injury, fire and product damage.
To avoid personal injury and to prevent fire or damage to this product or products connected to it, review and comply with the following safety precautions. Be aware that if you use this probe assembly in a manner not specified the protection this product provides may be impaired. Only qualified personnel should use this probe assembly.
Use only grounded instruments.
Do not connect the probe ground lead to a potential other than earth ground. Always make sure the probe and the measurement instrument are grounded properly.
Connect and disconnect properly.
Connect the probe output to the measurement instrument and connect the ground lead to earth ground before connecting the probe to the circuit under test. Disconnect the probe input and the probe ground lead from the circuit under test before disconnecting the probe from the measurement instrument.

Do not operate the product in an explosive atmosphere.

IEC Measurement Categories

Definitions and Examples

No Measurement  Category not in CAT II, III or IV| Definition:| Many types of test and measuring circuits are not intended not in CAT II, III or IV to be directly connected to the mains supply. Some of these measuring circuits are intended for very low energy applications, but others of these measuring circuits may experience very high amounts of available energy because of high short-circuit currents or high open-circuit voltages. There are no standard transient levels defined for these circuits. An analysis of the WORKING VOLTAGES, loop impedances, temporary overvoltage’s, and transient overvoltage’s in these circuits is necessary to determine the insulation requirements and short-circuit current requirements.
---|---|---
Examples:| Thermocouple measuring circuits, high-frequency measuring circuits, automotive testers, and testers used to characterize the mains installation before the installation is connected to the mains supply.
Measurement Category II| Definition:| MEASUREMENT CATEGORY II is applicable to test and measuring circuits connected directly to utilization points (socket outlets and similar points) of the low-voltage mains installation.
Examples:| Measurements on MAINS CIRCUITS of household appliances, portable tools and similar equipment, and on the consumer side only of socket-outlets in the fixed installation.
Measurement Category III CAT III| Definition:| MEASUREMENT CATEGORY III is applicable to test and measuring circuits connected to the distribution part of the building’s low-voltage mains installation. To avoid risks caused by the HAZARDS arising from these higher short-circuit currents, additional insulation and other provisions are required.
Examples:| Measurements on distribution boards (including secondary meters), photovoltaic panels, circuit breakers, wiring, including cables, busbars, junction boxes, switches, socket-outlets in the fixed installation, and equipment for industrial
use and some other equipment such as stationary motors with permanent connection to the fixed installation.
Measurement Category IV CAT IV| Definition:| MEASUREMENT CATEGORY IV is applicable to test and measuring circuits connected at the source of the building’s low-voltage mains installation. Due to these high short-circuit currents which can be followed by a high energy level, measurements made within these locations are extremely dangerous. Great precautions shall be made to avoid any chance of a short circuit.
Examples:| Measurements on devices installed before the main fuse or circuit breaker in the building installation.

The charts given here are valid for no measurement category, not in CAT II, III, IV (¹).

Typical Input Impedance
Note that the input impedance of the probe decreases as the frequency of the applied signal increases.
The charts given here are valid for no measurement category, not in CAT II, III, IV (¹).

Environmental Specifications

temperatures up to +31 °C, decreasing linearly to 40 % at +50 °C
non-operating| 95 % relative humidity for temperatures up to +40 °C

(1) As defined in IEC 61010-031. See definitions explained on page 18 and 19.
Handling
Handle with care especially when fitted with the extra thin and sharp spring contact tip to avoid any injury. Note that the probe cable is a sensitive part of the probe. Do not damage through excessive bending or pulling. Avoid mechanical shock to this product in general to guarantee accurate performance and protection.
Use ground lead only for connections to earth ground.
The accessories provided with the probe have been safety tested. Do not use any other accessories than those “originally” provided.
When using Keysight oscilloscopes, use the special read out for detection of correct divying factor, if this option was purchased.

Maintenance

• Cleaning
  To clean the exterior of the probe use a soft cloth moistened with either distillated water or isopropyl alcohol. Before use allow the probe to dry completely.

• Changing the Probe Tip
  To change the probe tip use pliers to grip and pull it carefully straight out of its contact socket, along the axis of the probe. Do not grip the white plastic insulator or the housing with pliers, because the tip could be squeezed and cannot be removed and respectively the probe could be damaged. If the probe tip is removed, the new tip can be inserted with pliers into the contact socket, along the axis of the probe. In order to insert the probe tip completely into the housing, press the probe tip against a hard surface carefully.
  Most oscilloscopes provide a build-in function generator to verify the passive probe is compensated correctly. After changing the probe tip always use the build-in function generator or other stand-alone instrument to make sure the probe is safe to operate.

  Use pliers to grip and pull the probe tip carefully out of its contact socket.| Do not grip the white plastic insulator or the probe housing with pliers.

Adjustment Procedures

The probe can be adjusted for low frequency (LF) compensation and for high frequency (HF) compensation.
A factory calibration is possible at any time on request.
The trimmers are sensitive components. Too much mechanical pressure during adjustment might damage the trimmers.

• LF Compensation When the probe is connected to the oscilloscope input the first time probes cable capacitance needs to be matched to the oscilloscope input capacitance. This matching assures good amplitude accuracy from DC to the probes bandwidth.
  A poorly compensated probe clearly influences the overall system performance (probe + scope) and causes measurement errors resulting in inaccurate readings and distorted waveforms.
  LF compensation is performed by connecting the probe to the CAL – output on the oscilloscope front panel and adjusting the LF compensation trimmer to optimum square wave response. For clarification see below figures.

• HF Compensation
  Overshoot doesn´t necessarily need to be adjusted when connecting the probe to your oscilloscope for the first time.
  We recommend to use the following equipment for proper HF compensation:
  Rectangular waveform generator with a rise time faster than 700 ps, 50 Ω feed through and probe BNC adapter. If you do not have the appropriate equipment we are pleased to help you. Simply send a message to our service department.
  HF adjustment is performed by connecting the probe to the rectangular wave generator.

• DC Adjustment
  DC compensation is executed while connected to the oscilloscope. Use a precision input resistance of 1 MΩ ±0.01 %.

The accessories provided with the probe have been safety tested. Do not use any other accessories than those “originally” provided.
