Keisoku Giken LN-1000A-G7 electronic load
« on: April 07, 2026, 03:24:36 pm »
Hello everyone：

This electronic load has a current rating when connected to the power supply, and I think it may need calibration. Do you have any calibration methods or manuals that can help?

Here is their website: https://www.keisoku.co.jp/

If you send an email they might be able to help you out. I saw someone who had a different model from this manufacturer wrote in their blog that they asked them and had success in receiving a manual.

Hello TERRA Operative:
I have already inquired about calibration via email, and the reply is that calibration can only be performed in Japan. This cross-border return trip will cost several times the purchase price of the machine.

I copied the FLAHS data from the main SOC, then reverse-engineered the SCPI commands. The analysis showed CAL-related commands. I tried inputting them, and after re-flashing the modified BIN file, calibration was successful. Keisoku Giken has been conquered!!
