4.3.1 Scaling with Known Loads (On-Line Calibration)
For maximum resolution, find the maximum signal that will be applied to the
meter input.
• For regular voltage input, refer to the main body of Table 4-1.
• For millivolt or milliamp input, refer to the main body of Table 4-2.
Set the DIP switch positions as indicated at the top of either Table 4-1 or 4-2. The
numbers 1 through 8 in the top row of either table represent dip switches 1 through 8,
and the O, C or X directly below the number indicates the correct position of each switch.
• ‘O' Switch should be open or up.
• ‘C' Switch should be closed or down.
• ‘X' Switch is used to control excitation (refer to Table 2-3 to determine correct
position of these switches).
Once Dip switches have been positioned correctly, apply power. Proceed to the
RD.CF
(Reading Configuration) and set R2 equal to the value in the right hand column of the
chart.
