16 CLS Scaling Values
For linear mVdc, Vdc, and mAdc ranges, use 0.1% tolerance resistors.
Higher tolerances may cause significant errors. Correct any errors due
to resistor tolerance with the CLS’ built-in linear scaling. You can also
install other components (like capacitors) for signal conditioning; please
consult Watlow Anafaze for more information.
The next table shows scaling resistor values.
The next table shows the location of RC and RD on the analog input
board. (The analog input board is the upper board of the two-board set.)
A wire trace on the printed circuit board jumpers the RC position. When
you place a resistor in the RC position, cut the wire trace that connects
the two resistor terminals.
