Using the insulating plug
The Model 8010 comes with insulating plugs. These plugs can be installed in the TO sockets of the
8010-DTB and 8010-DTB-220 boards when you are testing two-terminal devices that are installed in
the axial-lead terminal posts. In general:
•
You will use the insulating plug when measuring lower resistance devices.
•
Do not use the insulating plug when measuring devices with resistances greater than 1 M
Ω
.
The three-pin socket on the device test boards inherently shorts the force and sense pins together.
When you are using the axial terminal posts in 4-wire mode, this can cause measurement errors. You
should insert the insulating plug into the three-pin socket when testing devices with axial leads in 4-
wire sense mode where a short between force and sense will cause measurement errors.
Do not use the insulating plug when testing devices with higher resistance (greater than 1 M
Ω
). Using
the plug for these tests may cause leakage measurement errors.
Using the 8010-DTB-CT
You can use the Model 8010-DTB-CT to test 2-terminal devices and 3-terminal devices. The test
board can be used with device adapters for Tektronix curve tracers (see next figures). Before
installing a device adapter on a device test board, make sure that you have the device adapter
bottom terminals lined up correctly with the test board. For example, if the device adapter has the
letters C, B, and E, make sure that you insert the adapter on the test board to the corresponding
letters.
