3.3.3 Running the Optional Step Test

Introduction
You can test the recorder's mechanical operation by running a "step test". This test is initiated by setting
switches as described in Table 3-4.
This test prints a step pattern, which is independent of any chart settings, with horizontal lines drawn by
both pens at each 10% increment on the chart (see Figure 3-4).
The test will run for one complete revolution of the chart before it returns to normal operation. The chart
revolution for the test takes approximately three minutes, regardless of configured chart speed.
WARNING
SHOCK HAZARD
When the unit is powered a potentially lethal shock hazard exists at the AC line connections at TB1 on
each printed circuit assembly (behing the chart plate). Make sure the unit power is disconnected before
starting the procedure. More than one switch may be required to de-energize the recorder.
Failure to observe this precaution can result in exposure to a potentially lethal shock hazard.
Procedure
Use the procedure in Table 3-4 to run the step test.
Step
Turn off the power to the recorder.
1
Make sure the cap is removed from the tip of each pen
2
and the chart is installed.
3 Loosen captive screw and swing out the chart plate.
Note the position of all eight switches on SW1 on the
4
printed circuit assembly (PCA) for each pen.
5 Being careful of the shock hazard at TB1, set
switches 1 and 2 in SW1 in the OFF position on each
pen's PCA. All other SW1 switches should be ON
(toward the edge of the board). This is configuration
#252 in Table 3-2.
6 Being careful of the shock hazard at TB1, place run
switch SW5 to the setup position (toward the top of the
board) on each pen's PCA.
Apply power to the recorder.
7
8 The recorder will begin the test. The duration of the test
is approximately 3 minutes. (When the test has been
completed the pens will move away from the test
position, but the recorder cannot return to normal
operation until the switches are returned to their
correct non-test settings.)
At the conclusion of the test turn off the power to the
9
recorder.
