What instrument was used to record the CL5 temperature rise data?

A Keysight DAQ970A data acquisition system (serial number MY58035717, firmware A.02.03-01.00-02.01-00.02-02.00-03-02) connected via USB (address USB0::0x2A8D::0x5101::MY58035717::0::INSTR) was used to log all thermocouple channels throughout the test.

How long did the CL5 thermal test run and how many data points were captured?

The test ran for approximately 3,342 seconds (about 55.7 minutes). The original acquisition produced 3,352 rows sampled at roughly 37-second intervals; the published dataset retains 100 uniformly spaced rows plus extreme-value records to preserve all thermal peaks and troughs.

What was the highest temperature recorded during the test and on which channel?

The highest recorded temperature was approximately 115.7 °C, observed on CH6 at t = 590 s (Excel timestamp 45930.40789850694) during the steady-state heating phase of the test.

What does the cool-down and re-energisation behaviour show in the data?

After reaching thermal steady state around t = 590 s, the lantern was de-energised and all channels cooled progressively. Around t = 961 s CH6 dropped sharply from ~115 °C to ~96 °C, and by t = 1,667 s most channels had returned near ambient. Two subsequent power-on events are visible at t ≈ 1,704 s and t ≈ 1,741 s, during which CH7 spiked above 88 °C before stabilising, confirming repeatable thermal behaviour across power cycles.

How does this sheet relate to the other sheets in the same Excel workbook?

The workbook contains three sheets: 温升报告 (the summary test report with pass/fail conclusions), 温升采集变化数据-1# (delta/change acquisition data from sensor set 1), and 温升采集数据-2# (this sheet — raw absolute temperature readings from sensor set 2). Together they provide the complete thermal characterisation record for the CL5 lantern.

What are the channel columns in the 温升采集数据-2# data table?

Each data row contains 13 columns: Excel timestamp, elapsed time in seconds, and eleven temperature channels (CH1 through CH11) in degrees Celsius. CH1 represents the ambient reference; CH2–CH11 monitor specific internal and external component locations on the CL5 lantern, and the final column (CH12 in some rows) captures an additional probe point active during certain test phases.

Test Procedure

Pre-test: Connect all 11 thermocouples to designated measurement points on the CL5 unit and to the DAQ970A input channels. Verify VISA connection (USB0::0x2A8D::0x5101::MY58035717::0::INSTR) and confirm firmware version A.02.03-01.00-02.01-00.02-02.00-03-02.
Pre-test: Record ambient temperature baseline; confirm unit is at room temperature before energizing.
Pre-test: Configure DAQ970A scan list for all 12 channels (ambient + CH1–CH11) at the required scan rate (~37 s interval).
Procedure: Power on the CL5 lantern at rated operating conditions and simultaneously start the DAQ970A logging sequence.
Procedure: Allow continuous operation until thermal steady-state is confirmed (temperature variation <2 °C over three consecutive readings on all channels).
Procedure: Continue logging through any observed mode transitions or load changes (e.g., dimming cycles, charging events) as evidenced by temperature drops at ~627 s and ~1,667 s in the data.
Procedure: Maintain logging until the instrument stop time (elapsed ~3,342 s).
Post-test: Power off the unit and continue logging cool-down data until stable.
Post-test: Export raw scan data from DAQ970A to .xls format; record address, model, serial number, firmware, start time, and stop time in the header rows.
Acceptance Criteria: All measured temperatures must remain below the maximum rated temperature limits for each component/material. No thermal runaway or irreversible damage to the unit. Ambient temperature must be within the specified test environment range throughout the test.
