- Measures Resistance, R, Inductance, L, Capacitance, C, and Quality, Q, automatically
- 0.25% of reading, ±1 digit basic accuracy
- Eight decades of LCR measurement
- 2 selectable measurement frequencies: 100/120* Hz or 1 kHz (0.025% accuracy)
- 4-digit LED display with automatic decimal point
- User prompt facility for best accuracy
- Selectable series or parallel measure
- Integral 4-terminal test fixture
- External bias voltage up to 50 V possible
- Input protection against charged capacitors up to 10mF and 50V
- Model 6403 is equipped with an interface for the limits comparator model 6422. Test limits can be defined either of two ways. In the first of these, the upper and lower acceptable values are set in the two banks of thumbwheel switches. Alternatively the PASS band can be determined using a nominal value and upper and lower percentage tolerance. Three indicators are available to show where the measured value lies with respect to the upper and lower pass band limit. The same information is also available at 3 floating relay contacts of the 6422 comparator
- Automatic indication for overrange or underrange
- Easy operation by means of only 6 keys
- Automatic selection of measurement range (lockable if many components in the same range are to be measured) and automatic distinction between L and C
- Validity of measurement after 1 second maximum
- 2 measurements per second
- An adaptor for axial lead components is provided with the unit
- Selectable internal 2 V bias voltage for measurements of electrolytic capacitors
- Detailed operation manual
*120 Hz measurement frequency available as factory-fitted option.
