Test Procedure
- Pre-Test: Verify the X6PRO unit is fully charged and in normal operating condition. Zero or confirm calibration of the reference tank gauge. Record ambient conditions.
- Setup: Connect the X6PRO to the reference pressure tank. Set the device preset value to the first test point (20.0 psi).
- Inflation: Activate the X6PRO and allow it to inflate to the preset cutoff value. The device will stop automatically at the preset pressure.
- Reading: Record the X6PRO onboard display value (产品显示值) and the reference tank gauge value (气罐显示值) simultaneously at cutoff.
- Repeat: Depressurize the system, advance to the next preset value (40.0, 60.0, 80.0, 100.0, 120.0, 140.0, 160.0 psi), and repeat steps 3–4 for each point.
- Second Sample: Repeat the full sequence for sample 2# under identical conditions.
- Post-Test: Depressurize all connections. Record any anomalies or deviations observed during the test.
- Acceptance Criteria: The X6PRO display reading should closely track the reference tank gauge value at each preset point; deviations are evaluated against the product’s stated accuracy specification.

Observations:
- Sample 1# showed the largest single deviation at the 20.0 psi preset: the display read 24.0 psi against a tank reference of 23.97 psi, a display-over-preset offset of +4.0 psi. This may indicate a slow-to-respond cutoff at low pressures.
- At 140.0 psi, both samples underread relative to preset: Sample 1# displayed 137.7 (tank: 138.59) and Sample 2# displayed 137.9 (tank: 138.45), suggesting a consistent slight under-pressure at this point.
- At 160.0 psi, both samples overread: Sample 1# displayed 161.5 (tank: 162.44) and Sample 2# displayed 161.0 (tank: 161.84).
- Across mid-range points (40–120 psi), both samples tracked the reference gauge closely, with display-to-tank deviations generally within 1 psi.
- Sample 2# demonstrated more consistent tracking than Sample 1# across the full pressure range.
Conclusion
| Parameter | Details |
|---|---|
| Result | Static pressure accuracy measured at 8 preset points from 20–160 psi for 2 samples |
| Standard | Internal ETENWOLF QC Protocol for Air Pump Products |
| Conditions | Static indoor measurement; pressure held at cutoff; reference tank gauge used |
| Samples Tested | 2 units (1# and 2#) |
| Notable Deviation | Sample 1# at 20 psi: display 24.0 vs preset 20.0 (+4.0 psi); both samples slightly low at 140 psi |
| Mid-Range Performance | Both units within ~1 psi of reference gauge from 40–120 psi |
| Verdict | Acceptable mid-range accuracy; low-end (20 psi) and high-end (140–160 psi) calibration warranting review before final release |

Frequently Asked Questions
What does the static pressure accuracy test measure for the X6PRO?
The static accuracy test evaluates how closely the X6PRO’s onboard display matches a calibrated reference tank gauge when the device is set to inflate to a specific preset pressure and then held static at cutoff. It reveals systematic over- or under-reading tendencies across the device’s full operating pressure range.
Why does Sample 1# show a larger deviation at 20 psi compared to higher preset values?
Low-pressure accuracy in motorized inflation tools is often harder to control precisely because the pressure differential driving the cutoff switch is smaller and sensor sensitivity can vary near the bottom of the range. The 24.0 psi display versus the 20.0 psi preset for Sample 1# suggests the cutoff trigger may be slightly slow to engage at low pressures, a characteristic that typically improves with calibration adjustment.
How is the X6PRO display reading different from the tank gauge reading?
The X6PRO display reading (产品显示值) is what the device’s own internal sensor reports on its screen at the moment of cutoff. The tank gauge reading (气罐显示值) is the simultaneous pressure reading from an independent calibrated reference gauge attached to the same chamber. Comparing these two values reveals how accurate the device’s sensor and display are relative to a traceable reference.
What pressure range is the X6PRO rated for, and how does this test data relate to real-world use?
Based on the test data, the X6PRO was evaluated across 20–160 psi, covering common use cases such as car tires (typically 30–40 psi), bike tires (60–130 psi), and sports equipment. The mid-range performance (40–120 psi) was strong, with both samples staying within approximately 1 psi of the reference gauge — well within practical tolerance for most inflation tasks.
