MIL-DTL-16034B
3.26 Marking. Meters shall be permanently and legibly marked with the applicable information specified in
3.26.1 Terminal identification.
3.26.1.1 Portable meters.
a.
Polarity identification of DC meter terminals by a plus or minus sign on or near the applicable terminal
Note: The use of the minus sign is optional.
b.
Range identification of multiple-range meters
c.
Circuit identification of multiple-circuit meters
3.26.1.2 Switchboard meters. Polarity identification of DC meter terminals shall be indicated by a plus sign on or
near the positive terminal (see 3.6.4.2.1).
3.26.2 Dials. Dial markings shall be sharply defined and visible from the front of the case. These markings shall
not, however, be so conspicuous as to distract attention from the scale markings. Unless otherwise specified (see 3.1),
the scale markings and numerals, and items b, c, and d below, when applicable, shall be marked on the dial; items a,
and e through k shall be marked on the dial, on the front of the meter, or on an attached nameplate conforming to MIL-
STD-130.
a.
Type designation (see 1.2.1)
b.
Designation of the quantity measured (e.g., Volts, amperes)
c.
The words "direct current," "alternating current", or their abbreviations
d.
Serial number on portable meters
e.
Manufacturer's name or trademark (or symbol), or both
f.
Manufacturer's type or model number, or both
g.
The electrical quantity producing full-scale deflection when this differs from the full-scale value. Example:
FS=50 mv
Note: On zero-center meters, replace "full-scale" with "end scale." Example: ES=50 mv
h.
External accessories as required. Example: Use with 50 mv shunt
i.
Ratio of the appropriate current transformer, expressed as: 1000:5 or 1000/5 or 200:1 or 200/1
j.
Ratio of the appropriate potential (voltage) transformer, expressed as: 3300:110 or 3300/110 or 30:1 or 30/1
k.
Loop resistance of leads for external shunt of DC ammeter, when the lead resistance affects accuracy (see
3.27 Workmanship. Meters shall be manufactured and processed in a careful and workmanlike manner in
accordance with good design and sound practice. The interiors of meters will be free from metal fillings, grease or oil,
foreign material, dust, or other loose particles which might interfere with the normal operation of the meters.
3.27.1 Soldering. Soldering shall be in accordance with MIL-E-917.
4. VERIFICATION
4.1 Classification of inspections. The inspection requirements specified herein are classified as follows:
a.
Qualification inspection (see 4.3)
b.
Conformance inspection (see 4.4)
4.2 Test conditions and general instructions.
4.2.1 Atmospheric conditions.
4.2.1.1 Qualification tests. Unless otherwise specified herein, all qualification tests shall be made at ambient
temperature of 23 °C to 27 °C, at existing barometric pressure, and with relative humidity of 40 to 60 percent.
