should be confirmed by the SELF TEST switch
before measuring samples of interest. This test can
be done under all conditions of FUNCTION and
TEST SIGNAL settings. Tests under certain com-
bined conditions of FUNCTION and TEST
SIGNAL settings are done for five ranges. A test
for a range ends with a display of PASS (normal
operation) or FAIL (abnormal operation) and then
next range test is started. Range shifting for this
test is done automatically from lower to higher.
