14.3 Spanning Unit.

The following instructions explain how to use the POWERPOD-400 command signal to supply a given channel’s input with the proper span voltage and to set the display to read a transducer’s span value.

You must know four things prior to setting the display’s span value:

1.You must know the maximum signal level for the specific transducer connected to the channel to be spanned (5 VDC, 10VDC or 20mA).

2.You must know the maximum value to be displayed when the maximum signal level for the transducer is connected to the channel to be spanned.

3.You must insure that the channel’s multiplier is set to 1.0000.

4.You must know the channel’s ‘Span Value’. That is, the value that would NOW be displayed (prior to any adjustment) if the maximum signal was fed into the input of the channel to be adjusted.

1 and 2. If this information is not on the transducer itself, consult the manufacturer of the transducer. Their literature or other documentation should specify the maximum output signal from the transducer and the maximum value to be displayed at that signal level.

3.Setting the MULTIPLIER to 1.0000. Press MODE

Press 3

Press ENTER

Press 1, 2, 3 or 4 depending on which channel is to be adjusted. Press ENTER

Press 7

Press ENTER Press 4 Press ENTER

Press 1.0000 using the numeric key pad. Press ENTER

You have just set a channel’s multiplier to 1.0000.

4.If you do not know what the selected channel’s maximum display (Span) value is currently set to, follow these steps.

Notice that the last step in this exercise is to press ESC, not ENTER.

Press MODE

Press 3

Press ENTER

Press 1, 2, 3 or 4 depending on which channel is to be adjusted.

Press ENTER

Press 7
