3. To enter the correct model number press and hold
the SCROLL and DOWN keys and turn on the
instrument power, 8200 should be displayed.
Wait about 5 seconds and release the keys. The
display should remain 8200. Use the UP/DOWN
keys as necessary to change the displayed
number to match the first 4 digits of the model
number. After adjusting the first 4 digits to the
proper values, press the SCROLL key and the
display will change to 000-. Use the UP/DOWN
keys to set the last 3 digits of the model number to
the correct values. Press the SCROLL key and
the power up sequence will complete. The
Program and Tune mode parameters will need to
be re-entered (page 29 & 35 or the Software Ref.
Sheet, page 77, if already filled out).
1. Verify that the Program and Tune mode
parameters are correctly set (pages 29 & 35 or the
Software Ref. Sheet, page 77, if already filled out).
2. Turn off the power to the instrument. Wait about 5
seconds and turn the power on again. Confirm
that the model number displayed during the power
up sequence indicates that the output(s) is/are
present in the instrument. This number should
match the number on the label affixed to the lower
front of the display bezel. If model # is incorrect,
follow steps for "Model # displayed is incorrect".
3. Turn off the power to the instrument. Loosen the
front panel screw and remove the unit from the
housing. Inspect the Power Supply board
(Appendix A-1, page 64) for the presence of the
output device(s). Relay A is located at K1, Relay
B at K2, and Relay C at K3. A relay output will
appear to be a cube. The SSR Driver will appear
as a resistor and a jumper wire. The output will
not work if the hardware is not present.
4. Check the output operation by performing Test 6
as described in the Test section (page 54). If the
output(s) function(s) in the Test Mode re-examine
the Program and Tune Mode Parameters settings
(page 29 & 35, or the Software Ref. Sheet, page
77, if already filled out).
5. If the output appears not to turn off remove the
power to the instrument. Loosen the front panel
screw and take the unit out of the housing. Clip
the resistor located on the Power Supply board
(Appendix A-1, page 64) for the output(s) that
seem to stay on. A .01 microfarrad, 1 KV should
be connected from the terminal listed below, for
the output where the resistor indicated was
removed, to the AC ground.

Relay B
Relay C
Return the instrument to the case and tighten the
front panel screw. Turn the power on to the
instrument and check the operation of the
output(s).
