Four LCR meters have been investigated with the MIKES
and with the Metrosert impedance standards. The
investigated LCR-meters were from different
manufacturers: QuadTech 7600PLUS (denoted as A),
QuadTech 7600 (B), Agilent 4294A (C) and Wayne Kerr
6500B (D). Accuracy of the measurement with the LCR
meters depends on stability of the internal reference
standards and on the performed calibration procedures. The
meters A and B have so-called self-calibration capability
performed by use of a kit of four standard resistors [1].
To check the influence of the use of calibration kit on the
performance of the meters, two LCR meters, A and B, have
been adjusted by using two calibration kits from different
meters and, the same kit has been used in both meters. No
influence of the kit was noticed. For all instruments a
calibration procedure, including open and short circuit
zeroing was conducted by using of the same fixtures at the
end of the 1 meter cable set, beside of the unit C with the 2
meter cable [1-3]. For the meter D high frequency fixture
compensation (up to 1 MHz) has been applied with 100
