The B&K Precision Model 850 EPROM Eraser manual provides instructions for setting up and operating the device, including connecting the power source, positioning the EPROMs, and using the "START" button to select the erasing time. It also covers troubleshooting tips, such as adjusting the sound signal level and ensuring the correct power source is used to avoid operational issues.
Manual Overview
The B&K Precision Model 850 EPROM Eraser is designed for efficient and straightforward operation, capable of erasing up to five EPROMs in 40-pin DIP packages simultaneously. The device features a built-in timer with three settings: standard (15 minutes), short (7.5 minutes), and extended (30 minutes), which can be adjusted using the “START” button. The LED indicator assists in monitoring the erasing process, with a green light indicating readiness and a red light showing active erasing. To initiate the erasing cycle, users must connect the power source, place the EPROMs under the discharge tube, and press the “START” button according to the desired erasing time. The eraser emits a sound signal upon completion of the cycle, and users can adjust the sound level by setting a jumper near the bulb. It is crucial to use the recommended 12VDC power source to avoid operational issues. For safety, the device should remain in its working position during use to prevent UV radiation exposure.
Quick Issues Covered
- Diagnose LED indicators for erasing status and timer settings.
- Adjust erasing time using START button for different intervals.
- Power-up issues with non-recommended power sources.
Overview
The B&K Precision Model 850 EPROM Eraser is a compact device designed for erasing up to five EPROMs in 40-pin DIP packages simultaneously. It features high erasing efficiency and simple operation, with a built-in timer that can be set to standard, short, and extended erasing periods. The device operates on a 12V DC power supply and includes a UV tube with a lifespan of over 4000 hours. The eraser is equipped with a “START” button to set the desired erasing time, and a sound signal indicates the end of the erasing cycle. It is important to keep the device in its working position during operation due to UV radiation risks. Accessories include a wall-plug adapter and a pad.
Specifications
- Timer setting: 7.5, 15, and 30 min.
- Supply voltage: 12VDC 500mA, unstabilized

Controls & Indicators
The front-panel controls/indicators of the Model 850 EPROM Eraser include a “START” button and a “BUSY” LED. The “START” button is used to set the erasing time, and the “BUSY” LED indicates the status of the erasing process, lighting up green when the power source is connected and red during the erasing process.
Installation / Setup
The setup of the B&K Precision Model 850 EPROM Eraser involves connecting the power source, indicated by a green “BUSY” LED. EPROMs should be placed on a pad next to each other, covered by the Model 850 with their windows positioned under the discharge tube. The “START” button is used to set the timer for the erasing process, with options for standard, short, or extended erasing periods. The eraser operates on a supply voltage of 12VDC at 500mA and requires a wall-plug adapter. It is important to keep the device in its working position throughout the erasing process to avoid UV radiation exposure.
Operation
The Model 850 EPROM Eraser is designed for erasing up to five EPROMs in 40-pin DIP packages simultaneously. To operate, connect the power source, which will light up the “BUSY” LED in green. Place the EPROMs on a pad and cover them with the Model 850, ensuring their windows are under the discharge tube. Press the “START” button to begin the erasing process, indicated by the “BUSY” LED turning red. The erasing time can be set by pressing the “START” button once for 15 minutes, twice for 7.5 minutes, or holding it for more than one second for 30 minutes. The process ends with a sound signal, and the green LED indicates completion. The device should remain in its working position during erasing to avoid UV radiation exposure.
