The HM8018 LCR meter is a full-featured application-oriented measuring
instrument. In addition to the standard measure by an open and short calibration
procedure.
Optimum adaptation of the instrument to the unit under test is assured by 5
frequencies (100Hz, 120Hz, 1kHz, 10kHz, 25kHz) and 6 measuring ranges which may
be selected automatically or manually. For measurements on aluminium and
tantalum electrolytic capacitors a bias voltage of 1V is provided.
The HM8018 LCR meter sends a constant current through the test cables to the
unknown resistor R. The voltage drop across R will be measured. Also a small
voltage drop will be caused by the test leads RL. When measuring small
resistances (<1kO) it is advantageous to compensate for the cable resistances
by use of the offset mode. In order to compensate for the resistances of the
test cables the test cables are shorted at their end and the off-set push button
pressed. All errors caused by test cables and contact resistances are thus
eliminated.
If this correction is not used the resistance values obtained
will always be on the high side as the sum of all parasitic resistances in the
measuring circuit will be included in the result. HAMEG Instruments are well
known for oscilloscopes and test equipment for more than 50
years.
