11.5.8 DIAGNOSTICS
Sub-Menu
DAC FULL SCALE Menu Item When this menu item is selected, the Analog Output of the channel is forced to its full-
scale output, then
DAC UPDATED is displayed. This is useful when calibrating or trimming
the readout connected to the Analog Output.
DAC ZERO SCALE Menu Item When this menu item is selected, the Analog Output of the channel is forced to its
zero-scale output, then
DAC UPDATED is displayed. This is useful when calibrating or trim-
ming the readout connected to the Analog Output.
VERSION INFO Menu Item This menu item displays the part number and revision level of the firmware used by
this channels microprocessor.
DISPLAY ADC Menu Item The options for this menu item are:
•“
OFF ” will allow the [VALUE] button to cycle through “ TK ” (tracking value), “ HI ” (peak
value) and “
LO ” (valley value). This is the recommended option.
•“
ON ” will allow the “ AD ” (percentage of the Analog-to-Digital converter’s full-scale
digitizing capability) display source to be available along with “
TK ” (tracking value),
“
HI ” (peak value) and “ LO ” (valley value) when the [VALUE] button is pressed on
the front panel.
The Analog-to-Digital converter counts are displayed as a percentage from -100.00%
to 100.00%.
This can be used to establish the transducer’s electrical null prior to mounting. See
“Electrical Null and Transducer Mounting” on page 93 for this procedure.
LINEARIZATION Menu Item The options for this menu item are:
•“
ON ” will allow linearization data obtained from a 3-Point or 5-Point Known Dis-
placement Calibration to affect a channel’s scaled values. This is the recom-
mended option.
•“
OFF ” will not allow linearization data to effect the channel’s scaled values.
DISABLE CHANNEL Menu Item The options for this menu item are:
•“
ON ” will bypass the INITIALIZE and RUN modes of the channel. The track, peak
and valley values of the channel are forced to 0.
•“
OFF ” will allow normal operation of the channel.
