What to do if my Hoefer Power Supply shows error E1?
If the Hoefer Power Supply displays error E1, it means the voltage leads to the electrophoresis cell are not attached, or the current load is below 4 mA. Check all connections, ensuring sufficient buffer volumes contact all electrode wires and both gel surfaces. A constant volt run with a low volt setting may cause this. Press any button to clear the error.
What to do if my Hoefer Power Supply shows error E3?
If your Hoefer Power Supply shows error E3, it indicates an open circuit or a loose electrical connection. Check and correct any resistance problems, buffer volumes, and voltage leads. Verify the fit of power supply adapters if used. The output current may have fallen below the 4 mA limit of the power supply. Press any button to clear the error code.
What causes error E7 on a Hoefer PS300B Power Supply?
If the Hoefer Power Supply displays error E7, it means the voltage load is below 10 V. Check for any short circuits or electrical arcing. The buffer concentration might be too high, or a constant current run with low current may result in a voltage below the 10 V limit.
