Excel XL830 is good quality multimeter which can buy on Ebay , Aliexpress or other or in other Chinese eshops. If you have a budget under 10$ it is a very good choice.
Here are the pros and cons of this XL830L Multimeter:
Here is pros:
Here is cons:
- It has automatic power for battery saving – this is a useful feature for forgetful electricians as like me.
- The backlight turns off automatically after a short time of about 3 seconds,sometimes it is too short.
- Heavier opens to replace the battery.
- The fuse is soldered to the printed circuit board,this makes it difficult replacement.
Detailed description of multimeter XL830L:
At first sight multimeter interesting good design (to keep in mind its price ist under 10 $).
It measures all the basic electrical quantities they need: voltage AC or DC ,current up to 10A DC, electrical resistance, have test for diodes and transistors.
Display is 3 1/2-digit liquid crystal display (LCD), and each digit is 15 mm high.Display is equipped with a backlit green for measuring in the dark. Max display digits: 1999. Have auto polarity funkcion.
The rotary switch enables switching of electrical values and ranges ,of the multimeter,on XL830L works accurately and reliably. The rotary switch is often the cause of failure of Chinese multimeters.
It is equipped with a “Hold” function, which keeps the last LCD readout value.
Have three socket for measuring probes first in right VΩ mA , second in midle is COM and the third is left 10A.
Socket VΩmA is used to measure the voltage AC or DC,the current ranges of 200μA, 2m,20m,200m,electrical resistance is from 200Ω to 200mΩ. If you have probe in VΩmA socket can also test diodes or with Buzer checking electrical circuits.In socket VΩmA I recommend plug positive voltage and the red probe.
Socket COM is midle hole in multimeter Aways plugged in her black probe, for negative pole for DC voltage or current, Ground for AC voltage.
Socket 10A is only for the measurement of direct current in range 0-10A. Do not exceed this range !! Especially not for a long time!
Circuit board of XL830L :
View of the back side of circuit board multimeter can you see main integrated circuit (black round ),white-blue calibration pots,black sound buzer , soldered fuse,shunt for 10A current meter and connector for battery.PCB have standard quality and I have a really good impression.
How calibrate DC voltage on XL830L Multimeter?
If you will have multimeter more accurate or match with other measuring device , can you XL830L calibrate with a electric potentiometer – trimer on the back of the circuits.
First open case and slowly adjust the blue-white trimer with litle flat-blade screwdriver.
If you want buy this multimeter
multimeter I bought six times for myself and my customers have always been satisfied and no complaint. I buy on ebay for 6-7 USD (free shipping). Multimeter have realy good ratio price and quality. Under 10USD can you buy black DT830B for 3-4 USD is good choice but not have buzer,backlit display, stands. I recommended spend 2-3 USD more and buy XL830L.
