11. Set dip switches on bottom of printer to “on” position.
On top of printer, set the following: Age: 59; Height:
96; Race: 1; Sex: M.
Depress and release the print button to obtain a
printout. Observe printout. The printout should agree
with the settings. Also, the standard should be Euro
CCS (dip switches 1 and 2 in on position), the long
form, which is a questionnaire (dip switch 3 in on
position), and the volume over time graph (dip switch
4 in on position).
12. Return dip switches to position they were when unit
came in from customer. If unit is a loaner, or a new unit
being returned to stock, set all dip switches to off
position.
13. Hold down the print button and press/release the stop
button. Release the print button. A test printout should
print. At right side of top line, check the version of
software. It should be V3.2. If it is V3.1, it needs to be
changed. The “PROM” that controls this is in position
U5 on the main
pcboard. Replace existing Prom with
part number 610102-506. This Prom is software
version V3.2.
14. Perform agency tests on printer. These include the
ground continuity test and the leakage current test. If
the main pcboard, transformer or line filter was
replaced, perform the hypot test. Observe standards.
They are:
Ground continuity test: .2 ohm maximum
resistance with 10 amperes of current flow through the
earth ground line from the wall plug to a distant metal
point on the unit, probably the transformer screw
opposite where the ground wire is connected;
Leakage current test: 100 microamps or less
from any dead metal part on printer to earth ground,
with the printer ungrounded and powered up.
Hypot test: 1200 vac across the hot and neutral
(tied together) and earth ground for one second without
breakdown (voltage reduction).
