1. Can I measure the impedence of speakers? Yes, set the LCR45 to manual inductance mode and a fixed frequency of 1kHz or 15kHz. You can see the inductance, resistance, total impedance and phase of the impedance.
2. When testing speakers at 15kHz, I can hear a low frequency buzz from the speaker, not the 15kHz I've selected. Why? The LCR45 uses "bursts" of test signals, it is these "bursts" that you can hear. During each burst, the LCR45 is using the test frequency you've selected.
3. Can I measure arbitary impedances rather than just components?Yes. If the LCR45 has difficulty selecting the best mode and frequency then you can switch to a manual mode and test frequency to display the detailed impedance.
4. Can I use this in-circuit?No, it is not recommended for in-circuit use. Other component interactions can cause misleading results and damage may result from unexpected charged devices.
5. Is the LCR45 protected against charge on the probes?The LCR45 is protected against small charges on the probes (<5V on 22000µF, <25V on 10µF). Like all LCR meters, it is vital that you avoid charges on the probes.
6. Is the LCR45 better than the LCR40 for low inductances?Yes. The use of a finer resolution ADC provides significantly finer measurements when measuring below 1µH.
7. Is the LCR45 calibrated?Yes. Every LCR45 is individually calibrated to standards that are traceable to international standards.
8. Why does the calibration certificate cost extra if all LCR45s are calibrated anyway?The calibration certificate includes the results of a manual calibration verification process with results from 25 known standard values.
9. The display shows a "Calibration due" date of xx/xxxx.The "Calibration Due Date" is purely a recommendation. Nothing bad happens after that date. New LCR instruments will have a date shown that is approximately 12-18 months in the future. The generally accepted recalibration interval for this type of instrument is 12 months. The LCR40/45 can only be re-calibrated here at Peak which uses a very comprehensive 24 station rig, the calibration-due date is then set to 12 months from that moment. It is not mandatory to have a re-calibration.
10. What probes are included?Our universal gold plated hook probes (removable).
