Each AC/AC-LVDT Input channel is configured and calibrated via its channel
menu. Detailed instructions on operating the instrument in the SETUP Menu
mode can be found in "SETUP Menu mode" on page 23. A diagram of all menus
is located in "Setup Menu Reference" on page 157.
This menu controls the operation of this channel when the instrument is in the
RUN mode.
This enables or disables the channel's automatic zeroing function.
enabled, the channel will reset its tracking value to zero when the tracking value is
less than 10 display counts for a period of 10 seconds. This removes the effect of
slight temperature shifts in the transducer's output.
NOTICE
To compensate for the transducer's initial warm-up shift, the auto-zero function
operates every 2 seconds during the first 60 seconds of RUN mode operation.
The two options for this menu item are "ON" and "OFF".
This sets the frequency response, step response, and resolution of the channel
according to the table below. The tracking value, peak/valley detector values and
analog output on this channel are all affected. The default value of
suitable for most applications.
