Calibration values
If the Cal 1 and Cal 2 values are very close to zero, check to make sure that:
-
the amplifier is not in AC mode;
-
the filter switches (on the front of the amplifier) are not set to 0.05 Hz HP or 0.5 Hz HP;
- the amplifier channel switch is not set to the same number as another amplifier or device (UIM100C; HLT100C)
Also, increase the gain setting if possible.
