NOTE
If using a Dh4M that does not have zero correc-
. ..__
Using Table 6-3, perform the following steps to verify ac-
curacy of the lkQ range:
tion capability, record the oftset and subtract it
from the reading in step 6 to determine the zero
offset of the Model 263.
1. Place the Model 263 on the lk0 range and the Model
196 on the 3kQ range.
2. Still using the test setup shown in Figure 6-1, discon-
nect the triax cable from the Model 263 and short the
center conductor of the triax cable connector to its in-
ner shield.
3. On the Model 196, press the ZERO button. This cancels
the internal offset of the Model 196 and test lead
resistance.
4. Reconnect the triax cable to the Model 263.
5. Program the Model 263 to output .OOOOOkO.
6. The reading on the Model 196 is the zero offset of the
Model 263. Verify that the offset is ~10.
7. On the Model 196, disable ZERO and again enable it.
This zeroes out the offset of the Model 263 and Model
196, and test lead resistance.
