Version function comparison

Test device
The tester has 3 test points, TP1, TP2, TP3. The distribution of thesethree test points in the test block is as follows

On the right side of the test seat is the test position of the patchcomponent, there are numbers 1, 2, and 3 respectively, eachrepresenting TP1, TP2, and TP3

When testing a component with only 2 pins, the pins are not dividedinto the test order, 2 pins are arbitrarily selected for 2 test points, andthe device pins with 3 pins are placed in three test points respectively, regardless of the order. After the test, the tester automatically recognizes the pin name and test point of the component, anddisplays it on the screen.

When testing a component with only 2 pins, if two test points TP1andTP3 are used, it will automatically enter the continuous test modeafter the test is completed, so that the components on TP1 andTP3can be continuously and synchronously measured without pressingthe switch. If you are using the “TP1 and TP2” or “TP2 and TP3” test, only test once. To test again, press the switch once.

Before testing the capacitor, discharge the capacitor first, andtheninsert the test socket for measurement, otherwise the single-chipmicrocomputer of the tester may be damaged.

Calibration

The tester calibration is used to eliminate the errors of its owncomponents and  makethe final test results more accurate. Calibration is divided into quick calibration andfull-function

calibration. The operation method of quick calibration: short-circuit the threetest points TP1, TP2, and TP3 with wires, then press the test buttonwhileobserving the screen. The color of the screen will change to blackandwhite. After the prompt message “Selftest mode..?” appears, pressthe test button to enter the quick calibration process; if the promp

message “Selftest mode..?” appears, 2 seconds If there is nobuttonin the clock, a normal test process is performed, and finally theresistance value of the three test points of TP1, TP2 and TP3isdisplayed. After entering the quick calibration process, some datawill appear on the screen, just ignore it. Wait until a flashing string appears on the screen

After “isolate Probes!”, remove the wires that short-circuit TP1, TP2, and TP3. After the character string “Test End” appears on thescreen, the quick calibration is completed. When calibrating for the first time, use the full function calibration method.

Full function calibration needs to be entered fromthe functionmenu, and a 220nf  capacitor is also required. The full-function calibrationperforms a morecomprehensive calibration process and will takelonger. After entering the functionmenu, rotate the test buttontothemenu item “Selftest”, and then press the test button to enter thefull-function calibration process. The flashing string “short Probes!”appears on the screen, which is the same as the quick calibration. Use wires to shortcircuit the three test points and wait for thecalibration process to proceed. When theflashing string “isolateProbes!” appears on the screen, remove the wires that  shortcircuit the three test points and continue to wait for the calibration processtoproceed. Whenthe character string “1-||-3> 100nf” is output, install the prepared 220nf capacitors on the test points TP1 and TP3. Wait until the screen prompts “Test End”, the full-function calibration process is complete.

2.8 1-||-3

Capacitance continuous measurement method continuously teststhecapacitance value installed on TP1 and TP3. For small-capacitycapacitors, only this method can be used to measure the capacitancevalue. Measure the equivalent series resistance (ESR) of capacitorslarger than 90nF, and the resolution of ESR is 0.01Ω. Capacitorsabove 5000pF show the rate of voltage drop after charging. 2.9 DS18B20 Russian version does not have this function
DS18B20 is a temperature sensor that uses single-bus communication to transmit data. It has the same package (TO-92) asa triode. The figure below shows the pin distribution of DS18B20.

After entering the DS18B20 test function, the second line of thedisplay shows the connection relationship between the test socket and DS18B20, “1=GND 2=DQ 3=VDD”, which means TP1 is connected to DS18B20 GND, TP2 is connected to DS18B20 DQ, andTP3 is connected to DS18B20 VDD . The tester cannot automatically recognize DS18B20, so you must follow the instructions on thesecond line to install

Install DS18B20. The tester can read the 12-digit temperatureresultsmeasured by DS18B20, and display the corresponding temperatureinCelsius on the third line with a resolution of 0.0625°C. Scratchpad: The contents of the 8 storage units inside the DS18B20read by the tester plus the CRC check value of the last byte. Atotal of
9 bytes.

For example, the value read once is Scratchpad:
EC014B467FFF0C102A has the following relationship:

64-bit ROM: The globally unique device ID of each DS18B20readbythe tester. The ID has a length of 64 bits. Divided into 3 parts.

For example, the 64-bit ROM read by a DS18B20 is 64-bit ROM: 28FF4D58361604A1 Then there is

Note: Except that the temperature value (TEMP) is in decimal, therest are in hexadecimal.

The temperature measurement range of DS18B20 is -55℃-125℃.

Long press the test button to exit this function. 2.10 C(uF)-correction

This function is used to correct the measured value of large- capacitycapacitors. The default value is 0%. That is, there is no correction, thesetting range is -0.2%-8%, when it is a positive value, it will reducethemeasured value of the capacitance, and when it is a negativevalue, it
will increase the measured value of the capacitance.
After setting, long press the test button to exit. 2.11 IR_Decoder Russian version does not have this functionInfrared remote control decoding function. This function requiresa1838 integrated infrared receiver (pulse type). After entering thisfunction, observe the prompt on the display screen. The secondlinewill display the character string “”1=DOUT 2=GND 3= VCC”, thecharacter string means the connection relationship between the3test points on the tester and the infrared receiver, and the connectionmust be strictly inaccordance with the instructions. Only one infraredreceiver can be installed on the test seat empty or correctly. For other components, it is not allowed to short-circuit the test points withwiresto avoid unpredictable failures. The following figure shows theinstallation direction of an example infrared receiver.

TP1 is connected to the DOUT pin of the infrared receiver, TP2isconnected to GND, and TP3 is connected to VCC.

The infrared remote control decoding function supports two infraredremote control encoding formats. Format one

The above two formats are roughly the same, the difference liesinthelength of the pilot code. Format one is 9MS and format two is 4.5MS. Infrared remote control decoding function uses uPD6121 to indicateformat one, and TC9012 to indicate format two. Instructions
The infrared remote control decoding function can only be accessedfrom the function menu. Before entering the infrared remote control decoding function, there must be no components on the test baseandthe square wave output terminal. Enter the infrared remote control decoding function, after the “standing by…” string appears onthedisplay, install the integrated infrared receiver into the test socket andlock it. Then you can aim the remote control at the infrared receiver tolaunch. If you can identify the code used by the remote control. Thethird line will display a string of “>>>>>>>>>>>” characters, whichmeans a successful decoding, and the fourth line will display theencoding format used by the remote control. The fifth line showsthefirst byte of the user code (user code1), and the sixth line showsthesecond byte of the user code (user code2). The seventh line showsthe data code (data) and data inverse code
(~data), the last line is integrated display 32bit. All values of infrareddecoding function are expressed in hexadecimal format. The infrared decoding function only supports single-key mode, not continuous mode. When testing this function, it is found that several TV remote controls used for testing are all TC9012, the small Mp3remote control is uPD6121, and the remote control of the air conditioner cannot be recognized :-(). Due to conditions, no moretests can be done. To exit from this function, first remove the receiving head on thetest seat, and then press and hold the rotary encoder switch to exit. 2.11 IR_Encoder Russian version does not have this functionInfrared remote control coding function, this function requires aninfrared light emitting diode. The tester can control the infrared

light-emitting diode to realize the function of an infrared remotecontrol. Since the tester can only provide a driving current of about 6mAat most, the control distance cannot be compared with a normal infraredremote control. In the case of aiming at the infrared receiver, it isabout within 2 meters

The infrared remote control code supports two formats, whicharethesame as the decoding format of the infrared remote control describedabove. Also use uPD6121 for format one and TC9012 for format two. Instructions

The infrared remote control coding function can only be accessedfrom the function menu. Before entering the infrared remote control coding function, there can be no components on the test baseandthesquare wave output terminal. After entering the infrared remotecontrol coding function, connect  aninfrared light-emitting diodetothesquare wave output terminal. The negative electrode of the infraredlight-emitting diode is connected to the ground and the positiveelectrode is connected to the output. Wires can be used to extendthepositive and negative electrodes of the infrared light-emitting diodetofacilitate operation. The long leg of the infrared LED is positiveandthe short leg is negative

The leftmost column of the display is a “>” symbol, indicating theparameter currently being set. Short press the test button to switchbetween each setting item “>”. The second line “protocol” sets theencoding format to be used. Rotate the test button left and right toswitch between “uPD6121” and “TC9012

The third and fourth lines “user code1” and “user code2” set thefirst and second bytes of the user code, the left-handed test buttoncanbereduced by 1 unit, and the right-handed test button can be increasedby 1 unit

The fifth line sets the data code (data), the left-handed test buttoncanbe decreased by 1 unit, and the right-handed test button can beincreased by 1 unit. The inverse code of the data is automaticallycalculated by the data code and cannot be set manually

When setting the value of the user code and data code, in additiontorotating the test button left and right to change its value in units of 1, it can also be increased in units of 0x10. The operation methodistopress and hold the test button, but the long time cannot be toolong. If it is too long, it will exit from this function. This degree is not easytobesure at first. The sixth line is the emission control “emit:”. Whenthe”>” sign is moved to this line, rotate the test button left and right toemit infrared rays according to the data setabove. When youturnthetest switch, you can see a “->” symbol flashing quickly.Indicatesthat data was transmitted once. Operation example:

To use the infrared coding function to control an electrical appliance, you must first know the coding format of the remote control that controls the electrical appliance. So the first step is to use theinfrareddecoding function to read the code value of a button on the remotecontrol.

For example, if the TV is a Samsung LCD TV, press the volumedownbutton of the remote control, the decoded value is
TC9012 user code1=07 user code2=07
data=0B ~data=F4
All 32bit=F40B0707

Record the above data, and then in the infrared coding function, respectively set the protocol: TC9012 user code1=07 user code2=07data=0B ~data=F4 Then move the “>” symbol to emit: >emit:

The infrared light-emitting diode connected to the square waveoutput terminal of the transistor tester is aligned with the position of theinfrared receiver of the TV, and the test button is turned to start atransmission, and the TV can be controlled to reduce the volume. To exit from this function, first remove the  infraredLEDconnectedtothe tester, and then long press the test button to exit
Note: The transistor tester only supports two encoding formats, TC9012 anduPD6121. The values are all expressed in hexadecimal2.12 DHT11 Russian version does not have this function DHT11 is a temperature and humidity sensor, in addition to measuring temperature, it can also measure humidity. The pindistribution is shown in the figure below

After entering the DHT11 test function, the second line of the displayshows the connection relationship between the test socket and
DHT11, “1=GND 2=DQ 3=VDD”, indicating that TP1 is connected to
DHT11’s GND, TP2 is connected to DHT11’s DATA, TP3 is
connected to DHT11’s VCC . The N/A pin can be connected toTP1together with the GND pin, or it can be left floating. After the test is

successful, “TEMP” represents the temperature value, and “HUMI” represents the humidity value. All are displayed in decimal. To exit the function, long press the test button
2.13 SelfTest
Full-function calibration function.
2.14 Voltage

DC voltage measurement, up to 50V can be measured. The voltageto be measured should be input from the “voltage measurement” interface (do not input the measured voltage fromother interfacessuch as the “frequency output” interface, which will damage themicrocontroller). To exit this function, quickly rotate the encoder left and right.
