Each High-Level 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. The auto-zero
function can remove the effect of slight temperature shifts in the transducer's out-
put. The two options for this menu item are "
When enabled, the channel will reset its tracking value to zero when the tracking
value has never been more positive than +10 or more negative than -10 display
counts for any 10 second period.
For example, assume that the
mal points). If the tracking value never leaves the range of
any 10 second period, then tracking value will reset to
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.
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
