1-4. DESCRIPTION.
1-5. The HP Model 4262A LCR Meter is a general
P/N 8120-1378
purpose, fully automatic test instrument designed
to measure the parameters of an impedance ele-
ment with high accuracy and speed. The 4262A
measures capacitance, inductance, resistance (equi-
valent series resistance) and dissipation factor or
quality factor over a wide range at test frequencies
of 120Hz, 1kHz and 10kHz employing a five-term-
inal connection configuration between the com-
ponent and the instrument. The measuring circuit
for the device to be measured is capable of both
parallel and series equivalent circuit measurements
and the measured values are displayed by the two
three-full digits LED displays on the front panel.
A convenient diagnostic function, also featured in
the 4262A, is actuated by a SELF TEST switch.
This confirms functional operation of the instrument.
1-6. The measuring range for capacitance is from
0.01pF to 19.99mF, inductance from 0.014H to
1999H, and resistance from ImQ to 19.99M2,
which are measured with a basic accuracy of 0.2
to 0.3% depending on test signal level, frequency,
and measuring equivalent circuit, and at typical
measuring speeds of 220 to 260 milliseconds at
