I would imagine CEM or Extech would provide the adjustment procedure. Someone else had asked me recently about this and I believe Extech supplied it to them. |

I emailed CEM a while ago, but in the meantime I took off the back of the meter and used the pot at the bottom left of the metal shield on the board to fine tune the dc voltage. The pot is very sensitive and it probably took me about 20 minutes to adjust the meter. I would't be surprised if something else is out of whack now, but the dc voltage readings more closely follow the voltage reference that I have. |

Good day. You have successfully obtained the calibration procedure for the DT-9969. If it's not difficult, please share) |
