1-1. What is the purpose of the Navy's
Metrology Calibration Program?
1. To provide the fleet with new types
of test equipment
2. To provide quality control for your
test equipment
3. To improve the efficiency of
sophisticated electronic systems
4. To establish test equipment pools
from which technicians can borrow
1-2. At each higher echelon METCAL
calibration laboratory, the accuracy of
the test equipment increases by a factor
of
1. 10
2. 2
3.
100
4. 4
1-3. Most equipment technical manuals
contain voltage charts. For which of the
following purposes are they used?
1. To list the equipment's power
supplies
2. To list the input power requirements
of the equipment
3. To provide handy reference guides
for calculating voltage drops across
fixed impedances
4. To list correct voltages at major test
points

1-4. Which, if any, of the following
statements correctly describes the effect
input impedance of test equipment can
have on readings taken?
1. The greater the input impedance of
your test equipment, the less accurate
the readings
2. The lower the input impedance of
your test equipment, the more
accurate the readings
3. A piece of test equipment with an
infinite input impedance will absorb
no energy and readings will be more
accurate
4. None of the above
1-5. A piece of test equipment with a low
input impedance can cause readings
taken to be inaccurate. To eliminate this
problem, the input impedance of your
test equipment should exceed the
impedance of the circuit under test by
what minimum ratio?
1. 1 to 1
2. 2 to 1
3. 10 to 1
4. 100 to 1
