< Wait for the test to start >
• While waiting for the analog output test to start, the measured value of the set analog output
element is output.
• During analog output testing, output is performed without any relationship to the analog output
element setting.
•
After leaving the analog output CH1 test mode, the analog output returns to the ordinary operation state.
• The test mode is for checking the connection of the analog output when there is no input.
•
The output during this test cannot be varied by analog output adjustment (zero adjust, span adjust).
(Refer to ySetting menu of “ Basic settings.”)
