Figure 3-12:
The analyzer is placed in Zero Calibration mode. The mode field of the
display will read ZERO CAL R.
The analyzer is placed in span calibration mode as part of performing a low
span (midpoint) calibration. The mode field of the display will read LO CAL
R.
The analyzer is forced into high range for zero or span calibrations. This
only applies when the range mode is either DUAL or AUTO. The mode field
of the display will read HI CAL R.
The ground level from the analyzer's internal DC power supplies (same as
chassis ground).
Input pin for +5 VDC required to activate pins A – F.
Internally generated 5V DC power. To activate inputs A – F, place a jumper
between this pin and the "U" pin. The maximum amperage through this port
is 300 mA (combined with the analog output supply, if used).
