1. Zero adjustment
2. Span adjustment
Step 10: Set the decade resistor to the 100 percent of span resistance
level listed in Table 4-7. Adjust the SPAN potentiometer for
channel 1 until the calibrator numerical display is 3200.
Step 11: Repeat steps 9 and 10 until no adjustment is required for
either step.
Step 12: Perform a linearity check for channel 1. Set the decade
resistor to the various resistance levels listed in Table 4-7 for
your card, and observe the calibrator numerical display. Verify
that for each resistance, the display is within +
0002 of the
required number listed in the table. If any incorrect numerical
display appears, the RTD input card requires repair.
