Change 1
On page 115 the original text under the table “Resistance uncertainty” has been replaced with the following:
*1
Specification is valid for four-terminal connection using Option 70 Cable adapter. For two-terminal
connection from front panel terminal add
20 mOhm
.
Change 2
On page 115 the text under the table “Resistance uncertainty” has been added:
*3
In range 200 k
to 1000 M
specification is valid for two-terminal connection directly to front panel
terminals Hi-Lo.
Change 3
On page 58 added explanation of standard ohmmeter connection during calibration procedure
Calibration in resistance range of calibration points from 0 Ω to 100 kΩ must be done using Option 70 cable
adapter (four-terminal connection). Four-wire output resistance is defined at the test leads of the cable adapter.
Calibration in resistance range of calibration points from 100 kΩ to 1 GΩ must be done without Option 70
cable adapter application (two-terminal connection). Use front panel terminals Hi-Lo for connection of
standard ohmmeter.
On page 58 added calibration point 190 MΩ to the Table 12 “Resistance”.
