Overview
This chapter provides the basic operation procedures and describes names and functions on the display.
Product Introduction
LCR Pro1/Pro1 Plus (“the meter”) is a portable impedance measuring device for incoming inspection of
components, quality control, and laboratory use.
It is capable of measuring resistance, capacitance or inductance with 5 test frequencies (100Hz, 120Hz, 1kHz,
10kHz and 100kHz). It has a basic accuracy better than 0.1% for resistance and 0.2% for capacitance and
inductance measurements.
The meter has a pair of gold plated tips that can pick the SMD components with size down to 01005 (0.4mm x
0.2mm). The parasitic parameters of its probes are small and very predictable thanks to its unique mechanical
design. It significantly reduces the probability of measurement errors related to setup (such as wires, probes,
tips).
Features and Functions
Figure 1-1: LCR Pro1/Pro1 Plus Overview
The Navigation Button
The navigation button is used to browse and select different functions and parameters. It includes the “Up”,
“Down” and “Select” buttons as Figure 1-2 shows.

The navigation button can be used for shortcut operation as well. Therefore, user can switch settings quickly in
the measurement display and doesn’t need to go back and forth between the menu display and measurement
display. Detailed information is provided in Chapter 3: Making Measurements.
NOTE
When it switches from right hand operation to left hand operation, the “Up” and “Down” buttons are switched
position as well.
Turn On the Meter
To power on the meter, press the “Select” button once. The meter powers up with the most recently selected
measurement function.
Power Off
There are two ways to power off the meter:
1. Automatic power off. The meter powers off automatically if neither a measurement is performed nor any
button is clicked during the timeout period. To change timeout setting, please go to main menu ->
System -> Timeout. (Please refer to page 12: Timeout for the available options.)
2. Manual power off by selecting the turn off option from main menu as Figure 1-3 shows.
Figure 1-3: Turning off Display
NOTE
If test frequency is manually set to 10kHz or 100kHz, automatic power off may take longer to occur or not occur
at all. This is due to the meter being more sensitive at 10kHz or 100kHz. It may see parasitic values and keep
measuring even when the tips are open.
Switching to Menu Screen from Measurement Screen
When the meter is in measurement mode, user can switch it to menu screen by pressing down the "Select" button for
half second or so until the main menu screen shows up. Figure 1-4 shows the meter goes to main menu screen from
active mode (measuring components). Figure 1-5 shows the meter goes to main menu screen from idle mode (not
measuring any component in measurement mode).

Charging the Battery
The meter is powered by an internal, lithium-ion polymer rechargeable battery. It can be charged by connecting
to a computer USB port using a standard micro-B USB cable or, by using a USB power adapter. The USB power
adapter should have output voltage 5V +/- 5% with output current 100mA or greater. The USB power adapter is
available separately.
Figure 1-6: Charging the Meter
Battery Level Indicator
The battery icon in the bottom-right corner shows the battery level or charging status.
When the battery icon becomes hollow, it indicates that the battery remaining capacity is low and that it should
be recharged. The warning appears when the battery capacity is about 95% depleted. The unit is still operational
for a while, however the battery should be recharged as soon as possible.

CAUTION
Rechargeable batteries have a limited number of charge cycles and may eventually need to be replaced. The
meter battery isn’t user replaceable; it can be replaced only by an LCR Research Authorized Service Provider.
