1.1.

General instructions:

Thank you for purchasing a MS5308 LCR digital bridge meter.

The MS5308 LCR digital bridge meter is a professional

instrument for measuring inductance, capacitance and resistance.

It has many features, such as automatic identification, automatic

measurement range, high measurement accuracy and speed, wide

measuring range and so on.

An ordinary multimeter only provides DC mode for resistance

measurement, while the MS5308 provides both AC and DC

measurement modes. A variety of test frequencies up to 100Khz

can be provided for inductance, capacitance and resistance in AC

mode to meet the actual needs better.

Correct usage can ensure that the instrument will work precisely

for a long time. Please read the instructions carefully before using

and operate the instrument strictly in accordance with the

instructions .

means that that the measured object is capacitive.

3.2 Series-parallel connection mode description

This meter has series and parallel measurement modes. When the

capacitance value of the measured object is large or inductance

value is small, use the series mode for more accurate results.

When the capacitance value of the measured object is small or

inductance value is large, use the parallel mode for more accurate

results. This meter can select the measurement mode

automatically according to the measured object.

6 Measurement operation description:

6.1. Automatic measurement:

When the instrument is turned on, the instrument will enter

automatic identification mode by default. At this time, insert the

object to be measured to the measurement side. The instrument

will automatically recognize that the object to be measured is

capacitive resistance or inductor and display the measurement

value in the main display, and display a corresponding

D/Q/θ/value in the secondary display. In this mode, you can

change measurement frequency by operating Frequency.

6.2. Single measurement

When the instrument is turned on, the instrument will enter

automatic identification mode by default. At this time, you can

select L, C, R, DCR and other single measurement modes by

operating Function button. Read the measurement value on the

LCD display after inserting the object to be measured and

selecting the proper mode. In L, C, R mode, you can change the

measurement frequency by operating Frequency button, and you

also can operate Series/Parallel buttons to select parallel

connection measurement or series connection measurement.

6.3. Comparison and selection

When the instrument is turned on, the instrument will be switched

to single measurement mode for the objects to be selected.

Connect the sample objects to be selected at measurement port. At

this time, you can operate Comparison button to enter

comparison and selection mode. PASS or FAIL, will display on

the main display and the measurement value of current object will

display on the secondary display. In this state, press Setup button
