Astronics Test Systems Performance Test 3-1
Chapter 3
Performance Test
This procedure outlines a method of testing the Charge Amplifier for compliance
to the manufacturer’s specifications. The unit uses integrated circuits and very
stable parts and should not require calibration more often than every six months.
The amplifier may be in a single-unit cabinet or one that holds six units. The
following procedure is for a single unit, and must be repeated for each module. In
the event that a reading is out of tolerance the unit will require calibration. (See
Chapter 4.)
Test Equipment
Note: Equivalent equipment can be substituted.
Multimeter Fluke 8000A
Generators (2) Trig-Tek 346B Synthesized Calibrator.
Performance Test Procedure
CAUTION
The 115-230 VAC switch (S1, mounted on the unit’s circuit board) must
be at the proper setting. If 230 V Power is applied when this switch is set for
115 V RMS, circuitry will be damaged.
Check the unit to be tested for any loose or broken wires or signs of damage
caused by rough handling or dropping. While the unit is out of the chassis, check
S1, the 110-220 switch, is set for 110 if 105 to 120 Volts is to be used, and for 220
if 210 to 230 Volts is to be used. The unit will be damaged if plugged into 220
VAC power when set up for 110 VAC operations.
Plug the unit into the chassis and turn the POWER Switch ON; this is a single
switch at the left side of the chassis. The meter displays, and the POWER LED
will illuminate.
