How do you calculate continuity test workload in hours?

Divide the circuits to check by your continuity check rate for the base time, then multiply by one plus the allowance. With 120 units at 12 per minute and a 10% allowance, base time is 10 hours and required workload is 11 hours.

What does a continuity test actually verify on a harness?

It confirms every conductor runs to the correct pins with acceptable resistance — catching opens, shorts, and miswires before the harness ships. The workload here is the time to run those point-to-point checks across the lot.

Why include a probing and setup allowance?

Pure check rate ignores docking the harness on the fixture, seating probes, and reacting to a flagged net. The 10% allowance lifts a 10-hour theoretical block to a staffable 11 hours.

What is a good continuity check rate?

Automated bed-of-nails testers verify hundreds of nets in seconds, so the effective units-per-minute is high; manual probing on a complex harness is far slower. Enter the rate your actual method delivers rather than a mixed guess.

Continuity test workload vs harness test time — which do I use?

They use identical time math. Use continuity test workload when you are planning the point-to-point verification specifically; use harness test time when you are sizing the whole electrical-test station including hipot and functional checks.

How do I handle harnesses that fail and get retested?

Bump the allowance up or add a second run for the failed subset. The base rate assumes a clean single pass, so a low-yield harness family will overrun the 11-hour estimate without that adjustment.

Wire Harness, Cable & Electromechanical Assembly calculator

Continuity Test Workload Calculator

Continuity Test Workload converts the number of circuits you must verify and your probing rate into the hours of continuity testing a harness lot demands. Quality engineers and test-cell planners in wire harness assembly use it to plan point-to-point verification — the check that every conductor connects the right pins with no opens, shorts, or miswires. On dense multi-branch harnesses, continuity checking can rival build time, so estimating it protects the schedule and the ship date. Adding a setup and probing allowance turns raw check rate into hours you can actually staff.

What this calculator does

Estimate continuity test workload for wire harness, cable and electromechanical assembly using production-ready inputs so teams can plan labor hours, schedule the work, or check whether the job fits the available shift time.
Use it when continuity test workload in wire harness, cable and electromechanical assembly needs a defensible run time before a quote goes out.
It computes continuity-testing hours for a harness lot: circuits to verify divided by your check rate, scaled by a setup, probing, and delay allowance.

Formula used

Base continuity test workload time = continuity test workload workload ÷ continuity test workload completion rate
Required continuity test workload time = base continuity test workload time × allowance factor

How to use the result

Use it when planning point-to-point continuity verification capacity or quoting the test portion of a harness program's lead time.
It models a steady manual or fixture-based check rate; it does not distinguish quick automated bed-of-nails passes from slow manual probing, so mixed methods need separate runs.

Current U.S. benchmarks

The producer price index for copper and brass mill shapes stands at 559.593 (BLS, May 2026), up 76.8% from a year earlier. Quotes priced off last quarter's material cost miss this move. Global copper trades at $13,484 per tonne (IMF via FRED, May 2026).
Manufacturing hourly earnings average $30.27 (BLS, Jun 2026), up 4.4% from a year earlier. Median machinist pay is $28.24/hr (OEWS 2025), with state medians on each state page. Manufacturers have 529k open positions nationally (BLS JOLTS).
The U.S. has 5,397 electrical equipment and appliances establishments employing about 369,437 workers (Census County Business Patterns, 2023).
