備註 (Remark )
Though the internal test frequency is
approx. 250 Hz. However the accuracy adjustment are executed as :
* For the capacitance ( 2 uF, 200 nF,
20 nF, 2 nF ) range, the acuracy adjustment is compared with the "
Standard capacitor that tested under the 1 KHz frequency ".
* For the capacitance ( 20 uF, 200 uF )
range, the accuracy adjustment is compared with the " Standard capacitor
that tested on the 100 Hz frequency ".
* For the inductance ( 2 mH, 20 mH, 200
mH, 2 H ) range, the accuracy adjustment is compared the " Standard
inductor that tested on the 1 KHz ".
* For the inductance ( 20 H ) range,
the calibration is compared the " Standard inductor that tested on the
100 Hz ".
