Model 6517B Electrometer Reference Manual Section 6: Test sequences
6517B-901-01 Rev. C / August 2015 6-15
STAIRCASE: Use this option to select and configure the staircase sweep test. You are
prompted to enter the start voltage, stop voltage, step voltage, and the step time. After
entering these test parameters, use the EXIT key to back out of the menu structure.
Running the selected test
Perform the following steps to run the selected test:
1. Enable zero check and make sure the V-source is in standby (OPERATE LED off).
2. Connect and configure the Model 6517B for the desired test (see Configure sequence menu for
more information (on page 6-12)).
3. Select and configure the desired test.
4. Press the SEQ key. The selected test is displayed.
5. Press ENTER to arm the test. When the selected trigger source event occurs, zero check is
disabled and the test runs.
6. When the test is finished, zero check stays disabled and the V-source goes into standby.
7. The measured readings for the test are stored in the buffer. To access these readings, press
RECALL.
Test notes
1. If the IMMEDIATE trigger source is selected, the test starts immediately after it is armed. With
any other trigger source (except LID CLOSURE) selected, the test can be started by pressing
TRIG.
2. While a test is armed or running, the flashing "SEQ" message is displayed on the Model 6517B.
3. Readings are automatically stored in the buffer starting at memory location (reading #) zero.
4. The alternating polarity test is re-armed upon completion of a sequence. When the selected
trigger source event occurs, the test re-runs. Readings may be recalled, or the sequence re-
configured while the 6517B awaits the trigger. When the sequence is armed the first time, trigger
source is set to manual but can be re-configured to any other trigger source. To end the
sequences, press EXIT to return to normal operation.
