12.6 Channel Menu

Each High-Level Input channel is configured and calibrated via
its channel menu. Detailed instructions on operating the instru-
ment in the SETUP Menu mode can be found in "SETUP Menu
mode" on page 7. A diagram of all menus is located in "Setup
Menu Reference" on page 77.

12.6.1 OPERATION Sub-Menu

This menu controls the operation of this channel when the instru-
ment is in the RUN mode.
AUTO-ZERO Menu Item
This enables or disables the channel's automatic zeroing func-
tion. The auto-zero function can remove the effect of slight tem-
perature 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 decimal 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.
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.
