MANUALLY COMMANDING A TEST RESULTS REPORT
When reviewing the results of a completed test sequence, the user can manually command a test results report by
pressing the
key.
COMPENSATING FOR EXTERNAL LEAD LEAKAGE AND IMPEDANCE
Most test sequences can be run in a special mode which saves the measurement results for each test step and will
apply these saved measurements as offsets when the test sequence is subsequently run in a normal fashion in
order to provide lead error compensation. The details regarding the corrections available and the expected wiring
for each test step within the sequence are contained in the respective sections of this manual for each type of test
step.
NOTE
–
certain test step types are not suitable for lead compensation, see the respective sections of this manual
for each type of test step for details.
To perform a lead compensation on a test sequence, perform the following
–
•
Ensure that the display indicates that the 95x is in the base menu state, i.e., the display shows the date
and time. If necessary, press the
STOP
button to abort a menu and return to the base menu state.
•
Press the
SELECT
key.
•
The display shows the last used test sequence number and the name associated with that test sequence.
An example is -
SELECT TEST SEQUENCE
# 2 95x LINE HYPOT
•
As needed change the test sequence number to select the desired test sequence by using the Up Arrow or
Down Arrow keys (or using the numeric keys), and then press the
ENTER
key. The selected test sequence
is now made ready to be run.
•
Press the
LEADS
key. The display now shows the test sequence is ready to be run in lead compensation
mode, and the
READY
indicator flashes.
•
Ensure that the wiring is suitable for lead compensation. See the respective sections of this manual for
each type of test step in the selected test sequence for details.
•
Press the
START
switch on the front panel. While the sequence is running the
TESTING
indicator flashes,
and the selected test sequence is performed in the lead compensation mode.
o
Any pre-existing lead compensation data is discarded prior to the test sequence being run.
o
Each test step is performed in the normal manner, only the measurement results are used
differently. See the respective sections of this manual for each type of test step in the test
sequence for details.
o
Normal measurement limits are not enforced. Any programmed breakdown or arc detections
are performed and if detected aborts the test sequence with a failure.
•
After the test sequence has been run in this manner
–
o
The display temporarily shows a message indicating that the lead compensation for this
sequence is ready to be used.
o
The lead compensation measurements are saved internally in non-volatile memory and are
automatically retrieved with the test sequence when the test sequence is later selected.
