Input warning test (
terminal)
This test determines if the input warning of the current terminal test is
functioning properly. The multimeter sounds an alerting beep when the test lead
is inserted to the input terminal but the rotary switch is not set to the
corresponding location. The display indicates a flashing
annunciator
until the test lead is removed from the input terminal or until the rotary switch
is set to the
function.
Perform the following steps to replicate the input terminal warning test:
1
Turn the rotary switch to the
position.
2
Insert the red test lead to the input terminal.
3
Insert the black test lead to the
input terminal.

NOTE
Before conducting this test, make sure the beep alert function is enabled in the
setup mode.
