Current Shift Resistor

The CSR is an inline 10 Ω test resistor that matches the internal impedance of the Trimax Direct Current Meter (DCM). To confirm current sharing, introduce the CSR on a suspect wire and watch for the “current shift” on the alternative wire using the DCM or another multimeter — the change appears as you add and remove the CSR.

Why teams choose this tool

• Clear yes/no on shared current: insert CSR, observe the current shift when added/removed.
• Ready for the DCM: 10 Ω value is matched to the Trimax Direct Current Meter for consistent results.
• Works with other meters: usable with alternative multimeters if the DCM isn’t on hand.
• Low‑complexity, high‑confidence: minimal steps, repeatable method technicians can trust.

What’s in the kit

• CSR inline test resistor (10 Ω).
• Use with: Trimax Direct Current Meter (recommended).

Frequently asked questions

What does the CSR do?
It confirms whether current is present on shared wires and helps prove when two conductors are sharing current.

How do I use it?
Introduce the CSR onto the suspect wire, then measure the alternative wire with a DCM or multimeter; a visible current shift appears as you add and remove the CSR.

Why 10 Ω?
The 10 Ω value matches the internal impedance of the Trimax Direct Current Meter (DCM), making results consistent and easy to interpret.

Do I need the DCM?
The CSR is designed to pair with the DCM, but it can also be used with an alternative multimeter.
