Fluke VPS421-G Voltage Probe
The Fluke VPS421-G is a probe set for measuring voltage in conjunction with an oscilloscope or a motor drive analyzer. It is used when measuring high-voltage circuits while still needing a probe that attenuates the signal so that the instrument can work with it. The attenuation here is 100:1, so the probe's signal is scaled down before it reaches the measuring equipment.
It features a safety-shielded 4 mm probe tip, which is an important detail in practice. This means there is less exposed metal at the front of the tip, reducing the risk of accidental contact when working on systems and test setups. The probe is also designed for use in environments with high operating voltages and is rated CAT III 1000 V / CAT IV 600 V on individual contacts.
The set is well-suited for troubleshooting electrical and automation tasks, especially where higher voltages are involved and a reliable connection to the measurement point is desired. The included hook clip, reference lead with 4 mm banana plug, two alligator clips, and a test probe provide multiple ways to connect, depending on the nature of the point. This makes it practical in the field, where access to the measurement point is not always consistent.
If you need to choose a probe for a Fluke ScopeMeter or an MDA series, this is the type of accessory typically used to obtain safe and stable voltage measurement in the high-voltage range.
