Safety operation standards (ensuring the safety of personnel and equipment)

1. Core security principles

Prohibited live operation: Do not plug or unplug the probe/test line when connected to a voltage source to avoid electric shock or equipment damage;

Terminal rating: The voltage/current rating of each terminal of the probe must be followed (such as the maximum input voltage CAT II 300V RMS), and cannot exceed; The common terminal is at ground potential and is prohibited from connecting high voltage;

Personnel qualifications: Only qualified technicians can perform maintenance procedures, and ordinary users are prohibited from disassembling probes;

Environmental restrictions: Do not use in damp, condensing, or explosive environments; Do not operate in environments with conductive pollutants (pollution level 2).

2. Safety terms and symbols

Application scenarios of terminology/symbol meanings

Warning signs may cause personal injury or death. "Touching the metal part of the probe may result in electric shock

CAUTION labeling may result in equipment/property damage, as "cleaning with benzene solvents may damage the casing"

DANGER identification of immediately accessible injury risks (such as high voltage) probe high voltage terminal labeling

Grounding symbol protection grounding terminal probe grounding terminal identification

Refer to Manual for detailed information on probe body labeling

3. Cleaning and maintaining safety

Cleaning method: Only use a soft cloth dipped in "mild cleaner+water" or "isopropanol" to wipe the probe housing and remove dirt;

Prohibited solvents: Benzene, toluene, xylene, acetone and other solvents should not be used to avoid corrosion of the shell;

Component protection: Avoid liquid infiltration into the probe during cleaning to prevent circuit short circuits.

Product features and operating points

1. Core product features

Characteristic Description Application Value

Attenuation ratio of 10X (± 0.5% DC) expands the measurement range of the oscilloscope and adapts to high voltage signals

The cable length of 1.3 meters provides sufficient measurement distance to reduce interference with the tested circuit

Input impedance 10M Ω (± 0.5%)+8.0pF (± 0.8pF) High impedance reduces signal load effect, low capacitance adapts to high-frequency signals

Accessory compatibility compatible with Tektronix 3.5mm probe accessories that can be paired with hooks, grounding leads, etc., to meet various measurement scenarios

2. Key operation: Probe compensation

Due to differences in input capacitance among different oscilloscopes, probe compensation must be performed when replacing the oscilloscope to avoid distortion of low-frequency signals. The compensation steps are as follows:

Connect the probe to the calibration signal output terminal on the front panel of the oscilloscope (usually a 1kHz square wave);

Press the "AutoSet" button on the oscilloscope, or manually adjust to make the screen display clear square waves (1ms/division mode);

Rotate the micro adjuster using the included adjustment tool (003-1433-02) through the probe "compensation box opening" until the screen displays a completely flat square wave (without overcompensation/undercompensation, as shown in Figure 1).

! [Probe compensation waveform] (schematic diagram of "Undercompensated/Overcompensated/Relatively compensated" in the document)

Undercompensated: The square wave front rises and then falls;

Overcompensated: the square wave front falls and then rises;

Proper compensated: The front edge of the square wave is vertical and the top is flat.

Detailed specification parameters

1. Electrical characteristics (core performance indicators)

Characteristic specification description remarks

The attenuation ratio is 10X ± 0.5% (under DC conditions) and the system characteristics require the use of an adaptive oscilloscope

Input resistance 10 M Ω± 0.5% high impedance design to reduce signal attenuation

Input capacitance of 8.0 pF ± 0.8 pF, low capacitance suitable for high-frequency signals, reducing phase distortion

Compensation range of 8 pF~18 pF covers the input capacitance range of most oscilloscopes

System bandwidth (-3dB) TDS3054:500 MHz; TDS3012:100 MHz strongly correlated with oscilloscope model

Maximum input voltage CAT I: 400V RMS/DC; CAT II：300V RMS/DC； CAT III: The peak voltage of 150V RMS/DC needs to refer to the duty cycle (e.g. 590V peak when<50% DF)
