Model 4262 A
1kHz and 10kHz and about 900 milliseconds at
120Hz. The wide range capability of the 4262A
enables a measurement range from small capaci-
tances such as mica capacitors and the para-
sitic capacitance of a semiconductor device
through high capacitances such as the measurement
of electrolytic capacitors to be covered. A wide
range of inductance measurements from the in-
ductance of a high frequency transformer to that
of a power transformer can be measured. The wide
resistance range permits the measurement of wire-
wound resistors through the measurement of solid
resistors. In parallel capacitance measurements,
either a test signal level of 1Vrms, or 50mVrms
can be selected.
1-7. The 4262A has the capability of making
..capacitance, inductance, and resistance deviation...
measurements, This function is enabled by pushing
the A LCR switch to display the deviation of a re-
ference value. When the A LCR switch is depressed
the reference value is obtained and memorized
from the preceding measurement. The practi-
cal use of this feature is evident when it is desired
to make a measurement on a variable capacitor:
First, the minimum value is measured, then the A
LCR button is pushed. Minimum to maximum capa-
citance is now displayed as the capacitor is rotated
through its range. For parallel capacitance meas-
urements, test signal levels of either 1Vrms or
50mVrms may be selected. Other versatile 4262A
capabilities and features are, for example, the use
of internal and external de bias voltages, LC zero
adjustment, and options providing BCD output,
HP-IB interfacing capability, or a comparator func-
tion.
