Peak Atlas LCR Passive Component Analyzer
With the Peak Atlas LCR40, testing passive components is made easy as the meter runs automatically and provides you with the component type and value data on-screen. The LCR's smart technology selects the best signal level/frequency for each component that needs testing and then performs internal calculations. The LCR40 set has easy-clip test leads and comes with interchangeable probes. Simply select your mode (auto/manual) and connect the leads to the component to get your reads.
Automatically measure:
- Inductance (L)
- Capacitance (C)
- Resistance (R)
Scroll through your the on-screen results to view all data. Basic accuracy with resistors is 1% and accuracy for inductors and capacitors is 1.5%. View measurement capabilities under specifications below.
Important Note: Do not connect this instrument to power equipment or components that have stored energy or charge. This analyzer is meant for use with discrete and disconnected components.
Features
- Automatically measure inductance, capacitance and resistance
- Single measurement snapshots
- Automatic component type detection
