Initial Check-Out Procedure

2-22. Continuity ( )
To select the continuity function, first select the resistance function and then
press the button under the display. The button functions like
a three-position switch: the first button press enables visible continuity (the
indicator is displayed), the second button press enables audible
continuity (the is displayed), and the third button press cancels
continuity selection (the indicator disappears). The selection of
continuity is summarized in Figure 2-16. When continuity is detected, visible
continuity is indicated by the long bar across the top of the display. Audible
continuity (if enabled) is indicated by the tone emitted from the instrument.
Continuity is a quick check to verify whether circuit connections are intact.
The continuity detection threshold is typically <50% of the resistance range
selected for the fixed ranges (i.e. continuity is detected if resistance is less
than 100 in the 200 range, less than 1 k in the 2 k range, etc.). The
detection threshold is <100 for the autoranging k range, and <100 M
for the autoranging M range.
The 8062A can detect continuity for intervals as brief as 50 s (typically as
brief as 10 s). It extends the visible of audible indication to a minimum of
200 ms to make it easy to observe results. Note that while continuity is
enabled, the 8062A still makes resistance measurements and displays the
readings.

2-23. Initial Check-Out Procedure

Here is an easy procedure you can use to verify that your 8062A is operating
properly for most functions. All you need to perform these tests are the test
leads and access to a standard wall socket. Remember that you are not trying
to verify the instrument accuracy, but are simply confirming that the
functions work. Performance tests and calibration adjustments are presented
in Chapter 4. If the instrument passes the self-test when the instrument is first
turned on, then the display and the microcomputer are working properly.
