ToolWorld MS5308 Auto Range LCR Meter User Manual
General Instructions
Thank you for purchasing this LCR digital bridge meter. It 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
this meter 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.

Impedance Parameter Description (see Figure Ⅰ)
Z= R s +jXs=|Z|∠θ Rs-= |Z|Cosθ Xs = |Z|Sin θ
Xs /Rs =Tanθ θ=Tan -1(X s/Rs)
If θ > 0, it means that the measured object is resistant,
if θ < 0, it means that that the measured object is capacitive.
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.

Measurement Operation Description
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 button
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 measuremen
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 to select parameters,
and the sample value and error will display on the LCD. You can modify sample
value and error by operating direction arrows. Select the modification item by
operating Ok button, and confirm the settings. Press Comparison button again
to quit selection mode.
Deviation Proportion Measurement
When the instrument is turned on, the instrument will switch to single
measurement mode for the objects to be tested. Insert reference object in
measurement port, press Relevant Measurement button to save the current vale
(DCUR) as reference value (DREF). At this time, REL will display on the LCD.
Insert the object for measuring in the measurement port and press Relevant
Measurement button again. At this time, REL will flash on the LCD the
reference value will display on the main display, and the deviation proportion
REL% will display on the secondary display,
REL%=(DCUR-DREF)/DREF*100%. When DCUR is more than two times of DREF, OL% will display on the secondary display. Press Relevant Measurement button for more than 2 seconds to quit the measurement state.
Data Hold Function: press Hold button to stop reading
measurement value and show the current measurement value on the main display
continuously. At this time, only Communication and Backlight keys are
available. Press the Hold key again to return normal measurement mode.
Additional Functions
- Auto Power Off Function: To prolong battery life, when the external power supply is not used, APO will display on the LCD, which means that auto power off is available. The instrument will automatically power off without any operation for 5 minutes.
- Backlight Function: backlight will be enabled when you press Backlight button. Press Backlight button again toturn off the backlight. The backlight will turn off automatically after it is on for 60 seconds.
- Battery Power Detection Function: The meter has a battery power detection function. Battery power includes four levels and displays on the LCD screen. When “ ” displays for battery, please replace battery. This meter uses 8 × 1.5V Size AA battery. Batteries with the same model should be used for battery replacement. Please remember that you can’t use the meter until the rear cover is tightened.
