Follow the procedures described in section 7.2 for calibrating the zero points.
For each mid point:

Wait until
STABIL

below
0.5 ppb.
This may take
several minutes.

8.6. Special Calibration Requirements for Dual Range or
Auto Range
If Dual Range or Auto Range is selected, then it should be calibrated for both Range1 and
Range2 separately.
For zero and span point calibration, follow the procedure described in Section 7.2. Repeat
the procedure for both the HIGH and LOW Ranges
