Strain-Gage Input Channel10
10.5 Channel Menu
Each Strain-Gage 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.
10.5.1
OPERATION
Sub-Menu
This menu controls the operation of this channel when the instrument is in the
RUN mode.
AUTO-ZERO
Menu Item
This enables or disables the channel’s automatic zeroing function. The auto-zero
function can be beneficial by removing the effect of slight temperature shifts in the
transducer’s output. The two options for this menu item are “
ON
” and “
OFF
”.
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
DISPLAY.DECPT
menu item is set to
000.00
(two deci-
mal points). If the tracking value never leaves the range of
-000.10
to
+000.10
for
any 10 second period, then tracking value will reset to
000.00
automatically.
FREQ. RESPONSE
Menu Item
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
016. HERTZ
is
suitable for most applications.
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.
