Setting the Input Type/Recording Span/Linear Scaling
Setting the Channel Number
Set the channel number for which you want to configure the type of input, recording span and so
on. In this procedure, determine from which channel (starting channel) to which channel (ending
channel) you want to include in your configuration.
Starting Channel Number
The first three digits on the main display constitute the starting channel number.
• The first digit is the unit number. The second digit denotes the module number (slot number).
• The configurable range depends on the location where the power monitor module is connected.
A strain input module takes up twice the space of a standard-size module. This results in the
number of the slot following the one where the strain input module is installed being a missing
number. See page 3-8 for more information.
Ending Channel Number
The two digits that follow the starting channel number constitute the ending channel number.
• For the configurable range, see “Starting Channel Number” above.
• You cannot enter a channel number that is smaller than the starting channel number.
• If you have entered the same number as the starting channel number, only that one particular
channel is included in your configuration (configuration of the type of input, recording span,
etc.).
• When you move the cursor from the starting to the ending channel number, the ending channel
number becomes the same as the last two digits of the starting channel number.
Setting the Recording Span (SPAN)
Set the left and right spans within the limits of the input range. In the SPAN menu item, the left-
hand value is the left span and the right-hand value the right span.
Note
If you have connected any new strain gauge or changed the measuring range (initialization of settings or
reconfiguration of the system also changes the measuring range back to its default), you must go through
initial balancing. See Section 5.5, “Performing Initial Balancing/Initialization on a Strain Input Channel,”
for more information.
