Product Description

LCR-Reader-MPA: All-in-One Multimeter
LCR-Reader-MPA is an all-in-one multi tester with 0.1% and wide range of features, including oscilloscope, LED/Diode testing, AC/DC current/voltage testing, range of test frequencies including 100 kHz, frequency meter, continuity/open testing, etc.
When LCR-Reader-MPA's gold-plated tweezer tips make contact with a component, the device will automatically determine the type of component and best test parameters for that component. LCR-Reader-MPA will then measure the component with 0.1% basic accuracy; no set-up required.
The device can also be set for specific tasks; users can select their preferred test mode (L, C, R), test frequency (100 Hz - 100 kHz), test signal level (0.1, 0.5 and 1.0 Vrms), open/short calibration and more.
LCR-Reader-MPA was voted the bronze place winner for Plant Engineering's Product of the Year 2020 in the Maintenance Tools and Equipment category. MPA went up against products from Des-Case Corp, Exair and Fluke Corp. The winners can be seen in the May 2021 print edition of Plant Engineering.

Features
- Fully automatic and manual LCR, ESR, LED/Diode measurements
- 0.1% Basic Accuracy
- Automatic and manual test frequency selection: 100 Hz, 120 Hz, 1, 10, 20, 30, 40, 60, 75 and 100 kHz
- Easy Open/Short calibration and offset removal
- AC/DC voltage/current measurements - with up to 15 V for voltage testing
- 0.1, 0.5 and 1.0 Vrms Test signal level
- Automatic test signal reduction to 1.0 V for in-circuit measurements
- Signal Generator with Sine wave up to 100 kHz
- Oscilloscope transient voltage up to 100 kHz

Simplified Designed
LCR-Reader-MPA combines gold plated tweezers with a powerful multimeter in an ultimately portable device. At only 1 oz., it is easy to use and hold for extended periods of time, and is nearly undetectable in a bag.
The Li-Poly battery has a 80 hour continuous use battery and is rechargeable via micro-USB.
Controlling the Device
MPA uses a 4-way joystick navigational button that allows users to change basic test functions from the home screen - test mode, frequency, etc.
Pressing the button enters the menu where more specific test features are selectable - oscilloscope mode, signal generator, device settings, etc.
Display
All measurement values are instantly displayed on the backlit LCD. The primary and secondary values are displayed in the centre of the screen. Around the outside of the display is the test frequency, signal level, equivalent circuit, battery indicator and more.
Physical Specs
- 1 oz. weight
- Gold-plated tweezer probes
- Black or Grey backlit LCD display
- Handles components to a 0201 size (0.3 mm)
- 4-way joystick navigational button
- Li-Poly battery and micro-USB charging


LCR-Reader Kelvin Probe Connector
The Kelvin Probe Connector Kit is a two-wire connection that allows LCR-Reader to be used as a probe station. It also extends the reach of the device, allowing for components that are larger than the tweezers' tips.
The kit comes with 5 attachments
- 2 alligator clips
- 1 long pin probe
- 1 medium pin probe
- 2 multimeter 4mm jack plugs
- 1 spade connector
Oscilloscope Mode
This mode allows users to view the voltage waveforms. The analog display is best used when testing voltage waveforms on active circuit boards. The right side of the display shows the horizontal scale, the vertical scale, signal frequency and signal span are displayed.
The Kelvin Probe Connector kit is useful when using the oscilloscope mode for testing various nodes on a PCB.
