(13) GAIN ZERO ADJ. trimpots
Trimpots to compensate for amplifier offsets. If the baseline is not zero even if the
input is grounded, this offset can be compensated independently for the two GAIN
stages. Compensation procedure:
❏
Set the input coupling switches to zero to ground the inputs, and set the HIGH PASS
FILTER to 400 Hz.
❏
Set the GAIN range switch to 1, the GAIN factor switch to one and adjust the baseline to
zero using the left trimpot.
❏
Switch the GAIN factor switch to all positions and readjust to zero if necessary.
❏
Set the GAIN range switch to 10. If an offset is present, compensate it using the right
trimpot.
❏
Set the GAIN range switch to 100 and readjust the baseline if necessary.
