• Do not connect directly to mains electricity; the knob is a mechanical control component only.
• Do not touch terminals, internal circuits, or exposed electrical parts with wet hands.
• Fitting should be done by trained staff, lab technicians, or under qualified supervision.
• Do not force the knob if the shaft size or shape is not compatible.
• Do not overtighten set screws because this may damage the shaft or knob body.
• Keep the knob away from water, chemical spills, heat, flames, and damp storage areas.
• Do not use cracked, loose, broken, or poorly fitting knobs on laboratory power supplies.
• Keep small set screws and detachable parts away from very young children.
• Inspect equipment output carefully after replacement before student use.
• Store spare parts safely in a clean, dry, and organized location.

FAQ

1. What is the Power Supply Knob used for?

It is used as a replacement or control knob for compatible power supply units, allowing manual adjustment of voltage, current, range, or output settings depending on the instrument.

2. Is this knob suitable for all power supplies?

No, compatibility depends on shaft size, shaft shape, knob diameter, fitting style, and the power supply model. Confirm compatibility before use.

3. Does the Power Supply Knob require electricity?

No, the knob itself does not require electricity. It is a mechanical control part used on compatible powered equipment.

4. Can students replace the knob themselves?

Students should not replace the knob independently. Replacement should be performed by trained staff, lab technicians, or under qualified adult supervision.

5. Can this knob control voltage and current?

The knob can control voltage, current, or other settings only when it is fitted to the correct control shaft of a compatible power supply.

6. What should be checked before fitting the knob?

Check shaft diameter, shaft shape, control alignment, set screw type, knob size, indicator marking, and compatibility with the power supply model.

7. What should I do if the knob does not fit properly?

Do not force it. Use a correctly matched replacement knob to avoid damage to the control shaft, potentiometer, rotary switch, or equipment housing.

8. How should Power Supply Knobs be stored?

Store spare knobs and set screws in a clean, dry, labelled container away from moisture, dust, heat, chemicals, impact, and very young children.
