Introduction
Dear customer,
With the LRC Meter you have acquired a high-quality and state-of-the-art measurement appliance.
The device is essential to sound engineers because of its many possibilities. Users can carry out measurements
for induction, capacitance and impedance. During this action you can get a read-out on the D factor
(dissipation factor) on a second display. All measurements can be carried out on two different frequencies: 120
and 1.000 Hz. This allows a measurement of great accuracy.
The LCR700 has an Auto-Power OFF function, which helps conserve the lifespan of the battery, and a fuse
detection function to inform that a fuse is open or damaged. The use of a DC adapter can also serve to disable
the Auto Power OFF function. The RS232 port enables you to communicate with a computer.

Environment
Do not place the unit in environments which contain high levels of dust, heat, moisture or vibration.
Do not use the unit near water or other liquids. Make sure no water or other liquids can be spilled,
dripped or splashed on the unit.
This unit is developed for indoor use only. Do not use it outdoors.
Do not place objects on top of the unit.
Place the unit on a stable base.

Safety Requirements
(Read the safety requirements before using the meter)
Warning:
Before taking any measurements, please isolate the DUT from the power supply.
You should remove the test leads from the meter before replacing the batteries in order to avoid an electric
shock. Make sure the circuit switch is disconnected before taking any measurements.
Do not use the meter if test leads look damaged. Please check regularly.
Caution:
When you can’t turn on the meter…
1. When you have turned off the meter a few seconds ago, it is perfectly normal. Please wait a moment to turn
it on again.
2. When you can’t operate the meter properly, please turn it off and restart later.
3. When the segments are fading away gradually, please wait 10 seconds to restart the meter.
4. When you can’t turn on the meter normally, please press the power key for 10 seconds and the meter will
restart.
