Most installations on a flat, stable floor don't require it.\u003c\/p\u003e \u003ch3\u003eDoes the 110 V circuit need anything special?\u003c\/h3\u003e \u003cp\u003eThe machine ships with a preinstalled North American 110 V plug. Triumph specifies that it should plug into a standard outlet, not be hard-wired, and recommends a surge protector — the unit has no internal surge protection, and unplugging it clears the calibration memory.\u003c\/p\u003e \u003ch3\u003eHow fast is a routine balance?\u003c\/h3\u003e \u003cp\u003eThe spin itself takes 6 to 9 seconds. Add the time to read the position indicator, place the weight, and re-spin once to verify, and a routine passenger-car balance is well under a minute.\u003c\/p\u003e \u003ch3\u003eWhat's the residual accuracy on a clean balance?\u003c\/h3\u003e \u003cp\u003e±1 gram with the FINE button revealing the exact residual value. You can also raise the least-unbalance threshold (up to 40 g \/ 1.5 oz) so the display ignores small residuals on wheels where chasing the last fraction isn't worth the cycle time.\u003c\/p\u003e \u003ch3\u003eDoes it need calibration when it arrives?\u003c\/h3\u003e \u003cp\u003eYes. Calibration uses a 14-inch or 15-inch steel rim with tyre plus the 100 g \/ 3.5 oz weight that ships with the machine — one outside-rim spin and one inside-rim spin. Triumph notes that unplugging the unit clears calibration memory, so plug into a surge-protected outlet you don't intend to switch off.\u003c\/p\u003e \u003ch3\u003eWhat ships with the machine?\u003c\/h3\u003e \u003cp\u003eThe balancer cabinet, plastic safety hood, threaded shaft and hex bolt, cone-and-cup mounting set, quick-release wing nut, 100 g \/ 3.5 oz calibration weight, plastic caliper, wheel hammer, and product manual.
