Test Equipment & Setup

Item Detail
Test Equipment Tire / Basketball
Room Temperature 23 °C
Relative Humidity 60%
Power Source 12 V
Pressure Tolerance ±1 PSI

Test Procedure

  1. Pre-Test: Confirm ambient conditions — room temperature 23 °C, relative humidity 60%, power source 12 V.
  2. Sample Preparation: Prepare 2 units of the S7 tire inflator. Verify software version reflects the updated firmware.
  3. Car Tire Inflation (Sample #1): Connect the S7 to a car tire valve. Set target pressure and inflate. Record the displayed pressure versus measured reference pressure.
  4. Bicycle Tire Inflation (Sample #2): Connect the S7 to a bicycle tire valve using the appropriate adapter. Set target pressure and inflate. Record displayed versus reference pressure.
  5. Basketball Inflation: Attach the needle adapter. Inflate a standard basketball. Record displayed pressure versus reference.
  6. Post-Test Inspection: Inspect each sample for physical abnormalities. Verify battery charge/discharge function operates normally.
  7. Acceptance Check: Confirm all pressure readings fall within ±1 PSI of the reference value. Document pass/fail observations.

Frequently Asked Questions

What accuracy tolerance does the ETENWOLF S7 tire inflator meet?

The S7 meets an internal control standard of ±1 PSI across all inflation modes, including car tires, bicycle tires, and basketballs. Both test samples confirmed readings within this tolerance after the software update.

What inflation modes were tested in the S7 accuracy report?

Three modes were evaluated: car tire inflation (Sample #1), bicycle tire inflation (Sample #2), and basketball inflation. All modes were tested under the same conditions — 23 °C ambient temperature, 60% relative humidity, and a 12 V power source.

Did the software update affect the S7 inflator’s accuracy performance?

Yes, this test was conducted specifically after a software update. The results confirmed that the updated firmware maintains pressure accuracy within ±1 PSI, with no functional failures or appearance abnormalities observed on either sample.

What does the “For Reference Only” verdict mean in this report?

“For Reference Only” (供参考) indicates that the test data is provided as an informational benchmark rather than a formal pass/fail certification. Both samples performed within spec, and the accuracy test result is documented as OK.
