0.1% of reading basic accuracy.
Twelve decades of LCR measurement.
3 selectable measurement frequencies: - 100/120* Hz, 1 kHz or 10 kHz. (0.01% accuracy)
5-digit LED display with automatic decimal point. 
User prompt facility for best accuracy. 
Selectable series or parallel measurement modes.  
Automatic indication for overrange or underrange. 
Easy operation by means of only 8 keys.
Full auto ranging and automatic component identification. The instrument itself distinguishes between L, C or R after the component is connected. A manual override enables the minor term to be displayed. 
Capacitance up to 99.9pF in test leads or adaptors can be compensated for.
Validity of measurement after 1 second maximum.
2 measurements per second. 
Actual measured value can be frozen on the display with the HOLD function. 
Integral 4-terminal test fixture. 
An adaptor for axial lead components is provided with the unit. 
Selectable internal 2V bias Voltage for measurement of electrolytic capacitors. 
External bias Voltage up to 50V possible. 
Input protection against charged capacitors up to 10mF and 50V.
Model 6451/6452 is equipped with IEEE-488 and R5232 interface. 
It enables full control and measurement readout from a computer.
Model 6451/6452 is equipped with an interface for the limits comparator model 6422. 
Test limits can be defined in 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 comparator 6422.
