How to Perform Measurement
Resistance Measurement
All accessories can be used for the floating device measurement with the control
switch PULL position of the N1413A. Note that the N1425A/B and N1427A/B can
also be used for the grounded device measurement with the PUSH position.
Figure 3-11 Connecting Accessory for High Resistance Measurement using N1413A
For more information about using the accessories, see Operation Manual of each
accessory.
To apply a voltage over 21V, the Interlock terminal must be connected to an
interlock circuit. See “Interlock” on page 112.
To attach the N1413A/N1414A adapter, push it to the B2985B/B2987B
connectors.
Push the adapter in firmly until it locks in-place (< 1 mm spacing)
