Introduction
This manual provides operation information for the PSD90-3 Universal AC/DC Fuel
Quantity Test Set.
The PSD90-3 Universal AC/DC Fuel Quantity Test Set is an instrument that permits
complete functional checkout and calibration of an AC or DC Fuel Quantity System, on or
off the aircraft. The test set can accurately measure the capacitance of Tank Units,
Compensators, or entire systems. The test set can also simulate capacitance values for
the operation of Indicators, as well as measure the insulation resistance of Tank Units and
cabling.
Operation of the test set is automatic, with no manual nulling required.To evaluate a
particular system, connect the PSD90-3 to the applicable unit. Panel controls are set to
determine what is displayed on the digital display.
A rechargeable Lead Acid sealed battery powers the test set. The battery may be replaced
without the need of test set recalibration. Battery charge is displayed on the digital readout.
The test set is shipped with a chassis ground cable and power cord. In order to properly
test a system, specific aircraft interface cables are required but not furnished with the test
set.

General Information
2.1
General Information
The PSD90-3 is a general purpose test set and must be used in conjunction with an aircraft
specific interface cable in order to gain access to the aircraft fuel quantity system. Contact
VIAVI for interface cabling information on specific systems.
The following precautions should be observed at all times:
WARNING
Connect the PSD90-3 chassis jack to airframe ground before making other
connections, and keep connected during all test set operations (measurement and
simulation) unless otherwise specified in aircraft-specific procedures. Disconnect
chassis jack only after all other connections have been discontinued.
WARNING
When using in hazardous environment locations, the PSD90-3 test set should only be
operated from the internal battery. Do not operate on external power in a hazardous
environment.
WARNING
Only connect the PSD90-3 to external power in dry non-hazardous locations.
WARNING
Power cord connection to Front Panel connector must be clean and dry before
attaching. Replace protective cap on the Front Panel connector whenever power cord is
not connected.
The PSD90-3 battery should be recharged prior to first use and after every subsequent
use. For maximum battery life, the battery should be charged at least once every three
months.

2.3.1 ADC Calibration
This test performs the calibrations of each ADC, which also doubles as the ADC functional
test.
2.3.2 Ohmmeter functional test
This test verifies that the ohmmeter measurement circuitry is working correctly by
measuring a known resistance.
2.3.3 AC CAP functional test
This test verifies that the capacitance measurement circuitry is working correctly by
measuring a known capacitance. This test also verifies that the microbe slope detector is
functioning properly.
2.3.4 Cap simulator functional test
This test verifies that the capacitance simulator is functioning correctly.
2.3.5 Variable frequency functional test
This test verifies that the variable frequency capacitance circuitry is working correctly. This
circuitry is used in PROBE CHECK operation.
2.4
Resistance measurement
2.4.1 Low voltage resistance measurement mode
In some instances, aircraft wiring connections can be corroded (fritted.) The corrosion can
interrupt an electrical connection and cause a failure. Using test equipment with a higher
voltage can temporarily break through this corrosion and make the electrical connection.
This new electrical connection is temporary and may fail in the future. The Low Voltage
Resistance Measurement Mode does not break through the corrosion. To use the Low
Voltage Resistance Measurement Mode, the following procedure needs to be followed in
order to not destroy the corrosion.
NOTE
All other resistance modes have a higher voltage and will temporarily burn through the
corrosion. The test set must be placed in the Low Voltage mode before connecting the
PSD90-3 to the aircraft.

Contaminated Probe
The following sections describe the Contaminated Probe function.
2.9.1 AC/DC Automatic contaminated probe detection
While the test set is performing capacitance measurements, the contaminated probe
detector measures current through the fuel probe for the determination of possible
microbial growth or other contaminants in the fuel or on the probe. The result of this
measurement is shown using a phase error number in the top left of the display, as well as
a red LED light to the right of the display.
This measurement is only available in AC CAP and DC CAP (DC-) modes.
A displayed measurement of 0 degrees indicates no phase error, and therefore no
detected contamination. Any value greater than 0 degrees indicates that there is a possible
contaminated probe. If the measured capacitance is too low for the current range, the test
set will not be able to make an accurate phase error measurement and the test set will
instead display two dashes in the upper left.
The red LED to the right of the display illuminates when the phase error percentage
reaches a set threshold. This threshold defaults to 10% but may be set by the user.

based on measurement frequency. Probe Check mode varies the frequency from 5000 Hz
to 500 Hz, and will display the difference in ρF. Additionally, the percentage of error from
the displayed capacitance and the capacitance measured at 5000 Hz is displayed in the
upper left corner of the display.

Contaminated probe detector
The intent of the contaminated probe detector is to measure current through the fuel probe
that is resistive in nature, for determination of a possible existence of microbe growth on
the probe. While the test set is performing capacitance measurements, the contaminated
probe detector measures current through the fuel probe for the determination of possible
microbial growth or other contaminants in the fuel or probe. The result of this measurement
is shown using a phase error number in the top left of the display, as well as a red LED light
to the right of the display.
This measurement is only available in AC CAP and DC CAP (DC-) modes.

Chapter 3 Theory of Operations
Contaminated probe detector
The detector measures the current through the fuel probe that is due to the capacitance of
the fuel probe, and also measures the current that is due to leakage resistance. The
arctangent is performed on the ratio of these currents to get the phase. A pure capacitor
will have a phase of 90 degrees, and any deviation from this is displayed in the top left
corner in degrees. The degree of error is displayed if the phase error is 1 degree or greater.
The contaminated probe LED illuminates when the phase error exceeds the user set trip
point.
A displayed measurement of 0 degrees indicates no phase error, and therefore no
detected contamination. Any value greater than 0 degrees indicates that there is a possible
contaminated probe. If the measured capacitance is too low for the current range, the test
set will not be able to make an accurate phase error measurement and the test set will
instead display two dashes in the upper left.
The red LED to the right of the display illuminates when the phase error percentage
reaches a set threshold. This threshold defaults to 10% but may be set by the user.
