2-27. Initial Check-Out Procedure
Here is an easy procedure you can use to verify that your 8060A 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 5. If the instrument passes the self-test when the instrument is first
turned on, then the display and the microcomputer are working properly.
1. DC Voltage - Select the dc voltage function and the 20V range. Read the
battery voltage by touching the probe tip from the lead connected to the
V
Ω
S jack to the side contact (not the center pin) in the opening for the
battery eliminator jack on the right side of the instrument. Be careful not
to short the battery by connecting the side contact to the center pin.
Battery voltage should read 5.2V to 10V. If the voltage is less than
5.2V, the battery should be replaced.
Warning
Be careful not to touch the probe tips with your fingers,
or to allow the probe tips to contact each other.
The local line voltage is measured in the following step.
2. AC Voltage, dB, Frequency - Select the ac voltage function and the
200V range. Take note of the preceding warning and insert the probe
tips into a standard wall socket. The display should read the local line
voltage.
Now push the dB button. The display should read the line voltage in dB.
Now push the Hz button. The display should read the frequency of the
line voltage. Carefully remove the probe tips from the wall socket.
3. Resistance, Continuity, Conductance, Diode Test - Select the resistance
function and the 2 kΩ range. Touch the red (VΩS) probe tip to the A
jack so the VΩS input is shorted to the A input (this is the fuse check
procedure from section 2-4). The display should read .1000 ± .0100 kΩ
(neglecting lead resistance).
