Operating Instructions for Precision Oven

    Precision ovens are widely used in temperature-sensitive scenarios like electronics and laboratories due to their accurate temperature control and uniform temperature field. Correct operation ensures precision and extends service life. Below is the standardized procedure and core precautions.

I. Pre-operation Preparation

1. Equipment Inspection: Confirm no external damage, secure power/grounding connections, intact non-aging sealing strips, and unobstructed vents. For humidification models, check water tank level and replenish distilled water if insufficient.

2. Environment Confirmation: Ensure dry, well-ventilated environment away from flammables, no obstacles blocking heat dissipation. Maintain room temperature 5–35℃, avoiding direct strong light or drastic temperature changes.

3. Material Preparation: Use non-corrosive, non-volatile flammable materials. Select clean, dry suitable carriers (stainless steel trays, quartz boats). Strictly prohibit sealed or fully liquid-filled containers.

II. Core Operating Procedures

1. Startup Initialization: Connect power, turn on main switch, wait for system self-check (3–5 seconds, no display errors). Troubleshoot fault codes per manual before restarting.

2. Parameter Setting:

• Temperature: Set target per process, distinguish "working chamber/surface temperature". For precision, refer to internal probe data; fluctuation ±0.5~±2℃ (per equipment precision).
• Time: Set constant temperature duration (timing after reaching target; some support heating/constant temperature switching). Confirm 24h mode for continuous operation.
• Auxiliary: Set blower speed (avoid material displacement), humidity for humidification/dehumidification models, and multi-stage profiles for programmable models.

3. Material Loading & Startup: Place trays stably with ≥5cm clearance from walls/probes (no air duct blockage). Close door tightly and press "Start" to heat.

4. Operation Monitoring: Monitor display in real time; stop and troubleshoot immediately if over-temperature/alarm. Record internal temperature regularly for precision experiments.

5. Shutdown & Material Retrieval: Wait for internal temperature ≤40℃, retrieve materials with high-temperature gloves. Use rapid cooling function (if available) cautiously for heat-sensitive materials.

6. Shutdown & Finalization: Turn off main power, clean inner chamber, drain water tank (if equipped). Complete operation log (equipment No., parameters, materials, duration).

III. Professional Precautions

• Precision maintenance: Calibrate probes 1–2 times/year; replace sealing strips to avoid cold air leakage.
• Safety taboos: No flammable, explosive, corrosive materials; no door opening during operation (except door-open constant temperature models); no unauthorized disassembly—contact professional maintenance for faults.
• Maintenance: Clean air ducts/heat vents, inspect blower motor; descale humidification tank/tray. Disconnect power, keep dust-free and dry for long-term storage.
• Special applications: For ≥200℃, confirm material temperature resistance; for vacuum models, check vacuum/sealing, release pressure slowly to avoid material damage.

Summary

Core principles: accurate setting, strict monitoring, standardized maintenance. Follow procedures for precision and safety. Adjust per manual for different brands/models.
