Divider Circuit Offset Adjustment Procedure
1.
Set each trimmer pot to 0V on the wiper.
2.
Connect V
X
(input) to ground. Put a DC voltage of
approximatey 1/2 V
Z
(max.) DC on the V
Z
(input) with
an AC (squarewave is easiest) voltage of 1/2 V
Z
(max.)
peak-to-peak superimposed on it. Adjust X
OS
(R5) for
zero feedthrough. (No AC at V
0
)
3.
Connect V
X
(input) to V
Z
(input) and put in the
1/2 V
Z
(max.) DC with an AC of approximately 20 mV
less than V
Z
(max.).
Adjust Z
OS
(R
13
) for zero feedthrough.
4.
Return V
X
(Input) to ground and connect V
Z
(max.)
DC on V
Z
(input). Adjust output V
OS
(R
17
) for V
O
=
0V
O
5.
Connect V
X
(input) to V
Z
(input) and and in V
Z
(max.)
DC. (The output will equal K.) Decrease the input
slowly until the output (V
0
- K) deviates beyond the
desired accuracy. Adjust Z
OS
to bring it back into toler-
ance and return to Step 4. Continue steps 4 and 5 until
V
Z
reduces to the lowest value desired.
Notice that as the input to VX and VZ gets closer to zero (an
illegal state) the system noise will predominate so much that
an integrating voltmeter will be very helpful.
