Before diving into the manual’s contents, it is critical to understand the device itself. The TLD ACU-302-H-CUP is a high-throughput, automated TLD reader designed primarily for reading Harshaw TLD cards (typically DXT-RAD or XT-RAD type). The "H-CUP" designation refers to the specific heating cup or planchet used to heat the TLD chip, releasing stored energy as light (thermoluminescence). The ACU-302 model is known for its:

Here is a reference table from the typical manual:
| Error Code | Description | Manual’s Solution | |------------|-------------|--------------------| | E-01 | Carousel not detected | Reseat carousel; check opto-interrupter sensor | | E-04 | Gas flow low | Increase regulator to 25 psi; check for leaks | | E-07 | Heating cup thermal runaway | Replace H-CUP; check thermocouple wiring | | E-12 | Card jam at position 3 | Open lid, manually remove jammed card using tweezers | | E-20 | PMT (photomultiplier tube) saturation | Reduce gain; check for light leak |
The manual strongly advises not to attempt repair beyond cleaning optical lenses or swapping fuses. For PMT or motherboard issues, contact factory service. | Mode | Behavior | Use Case |
