    Using the operation：

1、Automatic measurement

When the instrument after the boot，Default state（AUTO）Automatic identification element pattern，

Automatic switching range，The default measurement frequency1KHz。

In automatic mode, the instrument automatically recognizes the impedance characteristics of the measured object.，

Automatic selectionL、COrRThe main parameters are extremely suitable for the series-parallel mode.。

Automatic measurement mode，The series-parallel mode depends on the impedance of the measured object.，

Impedance is high(>10KΩ)Select in parallel，Impedance is low(<10KΩ)Select Series。

2、L／C／R Mode measurement parameters

The main parameter selection，Default in the boot stateAUTO，Press“ModeC-L-R” （X）Key

The parameter is selected in turn as follows:“AUTO → AUTO-C → AUTO-L → AUTO-R → AUTO”

Series model“ESR”,Parallel model“RP” Xs／XpOnly in the main parametersR（Resistor）That is activated when you。

3、Selection of series-parallel measurement mode，In the corresponding main parameter mode, press “s.p/esr (R)”Key，

The parameter is selected in turn as follows:“AUTO- → P → S →AUTO-”。

4、Measurement frequency，This bridge is provided3A frequency Testpoint： 100HZ/1KHZ/7.8KHZ

Boot default frequency1KHz，Press“FrequencyFREQ” （F）Key

You can select different frequency point measurement“1KHZ →7.8KHZ →100HZ →1KHZ”。

5、Open circuit／Short calibration compensation，Press when the measuring clip is open or short circuit“Return-to-zeroZERO(C)”Key

The sweep Open circuit／Short calibration compensation。

(Measuring clamp open according to“Return-to-zero(C)”The key can be used for scanning and clearing open circuit. Clip short-circuit CKey Do short-circuit reset)

6、Manual mode，Press in any measurement mode“HAND(L)”Key

Can enter this mode（Manual mode），Drop out manual mode“HAND (L)”Key。

In this state，“Range（RNG）”Key available，Switching range“40R → 1K → 10K →100K →40R”。

Displays the following：

And series identification、 Impedance-Reactance

Capacitance（Inductor）Measurement、

QThe value of

Manual mode identification、 Measurement frequency、The main range、

7. Relative Measurement In the measurement mode State，Press“ParameterQTY”Key(Q)，No buzzer sound。

The current measurement is recorded and the relative measurement mode is entered.，Press again“Parameter(Q)QTY”Key，

Or mode switch, and so on，Will drop out relative measurement。

In relative measurement mode，The secondary parameter displays the relative error between the measured object and the recorded value.，Representation is a percentage。 Range is：-99.9%～+99.9%

   XJW01 DIYTroubleshooting manual for Xiaolin digital Bridge

A The bridge is not energized，Phenomenon2004Screen does not light，Causes and Solutions：

The three chips are in turn from left to right. LM358 AO4622 MP1584EN

II，Boot2004The screen displays two lines of black squares.，The causes of and solutions to the problems

1. 12VAdapter is damaged，Voltage low，Replacement。

2. After Shutdown10Seconds，Please do not rush to boot，Easy to crash，Wait a few minutes, and then boot。

3. Single-chip program damage，Need to re-burning process

4. The internal power supply chip damage，You need to replace。

Three。Cannot be normally measured using，Resistance cannot accurately detect resistance，Capacitance，Inductor error and large scale。

1. Accidentally measured the charged capacitor，The charging circuit。Breakdown bridge Test front-end protection diode，

All screws can be screwed off by the shell，Set panel，BNCLine bendable，

Don't cut，Remove the keypad，Detect the replacement breakdown by yourselfIN4148。

2. Clip line core Open circuit，Or short circuit of core wire and shielded wire，Use a multimeter to measure the cause，

Open the clip andBNCThe first self-repair。

3. Conduct bridge test clip open circuit and short circuit clear operation，The clip added togetherZERO ,Short-circuit reset。

Test clips do not clip together，According toZERO,Open-circuit reset。

4. Bridge calibration data disorders，You need to restore the default parameter value.，

To restore default parameter values：

According to “MenuMENU (M)Key5Seconds to enter the main menu。

Then press“Range（RNG）”(R)To enter the calibration mode

Continued for an additional Press5TimesZERO ( C)Key

Loads the default value: Z0 Under Become 76 Z= X.00（X= 1---15）

According toHAND (L) Save! （In this case, Buzzer does not） Is the restore default，

Then pressMENU Key，And then pressCLR (X )You can drop out，To return to the measurement state

Restore the default value is，Do you open，Short-circuit reset，

It can be measured，In this case, accuracy is better than that of0.5%
