  Used for diagnostics on electric rail and traction systems
  Can be used for current logging in data centres and industrial panels
  Suitable for inrush and frequency checks on motors and drives

What power source does it use and how long will it operate in the field?

It is powered by two AA alkaline batteries and features an automatic power‑off after 20 minutes to conserve battery life.

How does the flexible probe affect position sensitivity and measurement range?

The flexible probe allows access in confined spaces and measures up to 2500A with specified position‑dependent accuracy
distance from the conductor alters error according to probe length.

What environmental conditions can it tolerate during outdoor use?

The unit is rated IP54 for dust and water ingress and operates between -10°C and 50°C with specified humidity limits across the temperature range.

Which resistance and capacitance ranges are available for component checks?

Resistance measurement covers up to 60kΩ with 10Ω resolution in higher ranges, and capacitance ranges reach 1000μF with 1μF resolution for larger values.

How are recorded measurements managed and transferred?

Measurements can be logged and shared using wireless connectivity to compatible software, enabling storage to a smartphone and Cloud for reporting and traceability.
