Frequently Asked Questions - LCR45 Peak
How do I measure a capacitor with the LCR45?
Select the capacitance mode using the function switch. Connect the test leads to the capacitor (observe polarity for electrolytics). The reading will appear on the display. For large capacitors, allow a few seconds for stabilization.
What is the test frequency used?
The LCR45 uses a fixed test frequency of 1 kHz for all measurements, which is suitable for most general-purpose components.
How long does the battery last?
With a fresh 9V alkaline battery, typical battery life is approximately 20 hours of continuous use. The low battery indicator will warn you when replacement is needed.
Can I measure in-circuit components?
It is generally not recommended to measure components while they are in-circuit, as other components can affect the reading. For accurate results, isolate the component.
What does the 'Data Hold' button do?
The Data Hold button freezes the current reading on the display, allowing you to record it without worrying about fluctuations. Press again to release.
Is the LCR45 autoranging?
Yes, the LCR45 features auto-ranging which automatically selects the best measurement range for the component under test.
How do I use the Relative mode?
The Relative mode allows you to zero out the test lead capacitance or resistance. Connect the test leads together (or in the configuration you want to null) and press the Relative button. Subsequent readings will be relative to that reference.
What kind of battery does it use?
The device requires a standard 9V PP3 battery. Ensure you insert it with correct polarity as indicated inside the battery compartment.
How should I clean and maintain the LCR45?
To clean, use a dry, soft cloth. Do not use solvents or abrasives. Avoid moisture. For storage, keep in a dry place at room temperature. Replace battery if device is stored for long periods.
Can I measure resistance of a component while it is connected in a circuit?
Similar to capacitance, in-circuit resistance measurements can be influenced by parallel paths. For best accuracy, remove the component from the circuit.
