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
trimming 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
” (track-
ing 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 verify that the transducer’s output does not exceed the input
range of the instrument. If the Analog-to-Digital converter readings display more
than +/-10% when there is no load on the transducer, the transducer has a high
zero offset.
LINEARIZATION
Menu Item The options for this menu item are:
• “
ON
” will allow linearization data obtained from either the Signature Module or a
3-Point or 5-Point Known Load Calibration to affect a channel’s scaled values.
This is the recommended option.
• “
OFF
” will not allow linearization data to effect the channel’s scaled values.
This is useful when diagnosing problems in a calibration procedure.
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. This option is helpful
when a channel is installed but not being used. ERROR 46, which will nor-
mally occur when the (+)Sense and (-)Sense wires are not connected prop-
erly, will be surpressed.
• “
OFF
” will allow normal operation of the channel.
