 M-System's
Track/Hold model M2AMS is suitable for your requirement. Refer to the figure
below for the wiring.
The Track/Hold model M2AMS outputs the isolated input signal at the terminals
1 and 4 when the hold terminals (terminal No. 5 and 8) are short-circuited.
And it outputs the signal held when the hold terminals are open.
Connect as shown in the figure, and the voltage (current) between A and
B will be 0 while the hold terminals are short-circuited. Then when they
are open, the variation after the open command will be output between A
and B, which can be used to adjust the zero point. However the output signal
will be without bias. And if the input signal decreases after the terminals
5 and 8 are open, the output polarity (+, -) will be reversed. |
I
want to adjust zero point by remote contact signal. Do you have a suitable
transmitter?
