3.3 RUN Mode
After the INITIALIZE mode finishes, the instrument enters the RUN mode, its normal
mode of operation.
3.3.1 Display
Upper line
The display will show a channel number on the far left, followed by the channel’s oper-
ation messages.
For example, the Strain-Gage Input Channel will use the format below:
1
•
00000. PSIG "
where:
• Channel number: “1” is the channel number.
• Value type: The next character indicates the nature of the following value.
A blank character indicates the display is being continuously updated by “tracking”
the input signal to the channel.
A “
•
" character indicates the peak value (highest value seen since the [CLEAR]
button was last pressed).
A “
–
" character indicates the valley value (lowest value seen since the [CLEAR]
button was last pressed).
• Data value: “00000.” displays the value from the transducer in engineering units.
• Units label: “PSIG” indicates the engineering units being used (up to 4 charac-
ters).
• Tare indicator: A “
"
“ symbol indicates tare is off; a “
Ë
“ symbol indicates tare is on.
Lower Line
The contents of the display’s lower line is selected with the “
DISPLAY MENU
->
DISPLAY
MODE
” menu item as either displaying a channel or indicating the status of Limits. See
“Indicator Lights” on page 21.
3.3.2 [VALUE] button
After the channel number, the next characters indicate which data value for the dis-
played channel is shown. There are three (possibly four) data values available from
each channel:
• (blank), tracking data value
• “
•
", peak data value, (highest value since the peak/valley detector was cleared)
• “
–
", valley data value, (lowest value since the peak/valley detector was cleared)
• “
Û
", percentage of the Analog-to-Digital converter’s full-scale digitizing capability.
This data value is only available when the channel’s “
DIAGNOSTICS
->
DISPLAY ADC
”
menu item is set to “ON”.
Pressing and releasing the [VALUE] button cycles though the available sources for
data values for the displayed channel.
3.3.3 [CLEAR] Button
Pressing and releasing the [CLEAR] button will reset the peak and valley values of the
channel being monitored by the display to the track value. Additionally, any limits in
the instrument that are “latched” will be reset.
To clear the peak and valley values of the Input Channel regardless of which channel
is being monitored by the display, use the AUX1 or AUX2 control pins on the Input
Channel connector. See the particular chapter regarding that channel for details.
3.3.4 [CHANNEL]
button
If the configuration of the instrument contains more than one channel, the left most
characters of the display indicates which channel the display is monitoring. Pressing
and releasing the [CHANNEL] button will cause the next channel to be displayed.
If the “
