Figure 3.2-1: System Test Module in the Faraday Cage
NOTE:
The unit employs a safety interlock system which will prevent high
voltages from being impressed on the test sample unless the Faraday Cage
cover is positioned in the operate (cover down) position. As an added
precaution, it is highly recommended that the
HIGH VOLTAGE OFF
button be
depressed (High Voltage will be turned off) whenever the Faraday Cage cover is
lifted. Voltages in excess of ±5000 Volts are generated by the Control Unit and
are transferred to the test sample area during normal operation of the system.
Caution should always be exercised when working with high voltage. The
recommended operating procedures should be adhered to all times. Further, no
attempt should be made to modify the equipment or tamper with the interlock
system in any way.
NOTE:
For systems with Serial # 877 and higher disregard this section.
Unless specifically requested the unit is set for 115 VAC operation. If operation
from another line (Mains) voltage is required, the
VOLTAGE SELECT
switch on
the rear of the control unit must be set to the appropriate voltage and the fuse
changed to that indicated on the rear panel. Refer to Section 5.0 for conversion
instructions.
3.2 MANUAL
Mode
1. After the
STM
or the test sample has been secured and the Faraday Cage
cover returned to it’s operate position (cover down) check the control panel to
insure that all controls have been set as indicated in paragraph 2 of Section
3.1. Turn Power on by depressing the
POWER
button. It should latch in the
down position and the center display area should be illuminated. Allow the
unit to warm up for approximately 15 minutes prior to testing.
2. Select the
CUTOFF
level desired by depressing the appropriate button.
Refer to Table 3.1 for
CUTOFF
levels and test specifications.
