2. If not already on, push  on the Product.
3. Push the softkey labeled MODE until hvr shows above the right-most Product
softkey.
4. Set the multimeter for 2-wire ohms measurement and auto range.
5. Measure the High Resistance calibration performance at each resistance
point shown in Table 16. Deviations should not be greater than the specified
limits.
