The YR1030 measures voltage and resistance. It is suitable for batteries with the following electrochemical components: Lithium (LiIon, LiFePO4, LiMn, LiPo), NiMh, NiCd as well as lead batteries (single-cell or packed).
Important: The voltage must be in the range from 1mV through 28V DC! Do not exceed 28V, otherwise the device may be damaged and there is also a risk for your health when you work with higher voltages than the device is suitable for.
This said, I advise you to be careful in using this text and the information herein for your practical work! I take no responsibility for the things you do, it is your responsibility to verify the information here if it is critical for your work. I have done research and have read a lot of stuff which finally went into this description but I cannot take responsibility for everything written here, for example because some data has been taken from the manufacturer’s documents and some other data from third parties reporting on the subject.
So, please, be careful, if in doubt ask specialists and experts before you make avoidable mistakes which may harm you or damage your equipment or even household!
There are several things the YR1030 can do for you: It measures voltage and resistance, it can sort your batteries in classes and count the members of each class, and you can define the criteria for sorting, furthermore it is capable of four-lead measurement of resistance (if you do not know about this topic, I urgently recommend further reading).
There are automatic modi for resistance and voltage for a quick start, but you can also choose your measurement range manually for both measurements:
Resistance: 20mR, 200mR, 2R, 20R, 200R plus automatic mode (Auto) [R stands for Ohm]
Voltage: 2V, 20V, 28V plus automatic mode (Auto)
Take care NOT TO EXCEED 28V DC!
There is a battery inside the housing of the YR1030 which can be charged by USB, you need a micro-USB cable which is not part of the standard scope of supply.
The display can be lit, there is a special menu item to control this feature.
The configuration menu is in English.
An internal calibration is possible.
Measurement range voltage: 0-1,999V, 2-19,99V, 20–28,99V, Auto
Resolution voltage: 1mV, 10mV, 100mV
Measurement range resistance: 0-20mΩ, 20-200mΩ, 200-2Ω, 2-20Ω, 20-200Ω, Auto
Resolution resistance: 0,1mΩ, 1mΩ, 10mΩ
Temperature range of operation: -10°C bis +40°C
Power supply: inbuilt battery, charge via micro-USB socket with 5V, 1A
Size: 130mm × 72mm × 30mm
There is a bigger USB type A socket and a smaller micro USB socket. The type A socket is used for the contacting tools (test leads) which are especially designed for the YR1030! Never connect any other USB devices to this socket! This is no standard USB port, it is just the way the special connection tools for the YR1030 are connected to the YR1030!
The micro USB socket is only for charging the internal battery. You need some standard USB charger (or other appropriate current source) in order to charge the YR1030. Please, note that readings may not be precise anymore if the internal battery voltage drops too far. Keep the internal battery at a good charging state in order to measure properly and precisely.
There are four buttons which we call POWER, HOLD, RR and RU.
POWER: Switch on. To switch off: Hold for 5s, then confirm with yes by pressing HOLD (RR means no in this case and nothing will happen but a cancellation of the command). A short press of the POWER button switches on the menu.
HOLD: Short press activates the hold function so that the display keeps the measurement at the moment of pressing the button. Pressing HOLD for a long time (5s) activates the differential measurement. The current reading serves as zero level.
RR: Choosing the measurement range for resistance. In the menu you may scroll through the main menu items. Within a menu item it scrolls through the variables available.
RU: Choosing the measurement range for voltage. Scrolls through menu items. In case a main menu item has been chosen, it scrolls through sub-items.
Choose your contact tool. There are different tools available: The standard test leads, clamp tool with two clamps, and a battery-holder for round cells like the 18650.
In all cases, the device measures with the four-lead method! This means, that every pole has two contact tips (or contact areas respectively). The standard test lead shows two tips on both of the leads, and both tips must get in contact with the respective battery pole. Otherwise the measurement will not be precise and may grossly deviate from the true value.
You may receive the test leads (standard tool, clamps, round-cell holder) with more or less heavily twisted cables. This can be unpractical and annoying. One author has written that the leads are so-called twisted pairs and should not be further untwisted. But that is simply wrong! Indeed, you should untwist the cables carefully, this is possible by reversing the way the leads are intertwined. To shortly and precisely describe this process in English simply overburdens my knowledge of the english language, I’m sorry. But I’m quite optimistic that you’ll find your way through this problem. After the cables are not intertwined and twisted anymore it is a good idea to carefully fasten them together in pairs with cable ties e. g.
Do not invert the poles! Correct connection of the red lead to battery plus and the black lead to battery minus is essential! Reversing it may damage the YR1030!
The clamps must have electrical contact with both tranches!
The battery holder has two fine tips in the middle of each connector, but the outer hollow shaft wherein this inner tip is hold and guided must also get in contact with the battery pole! Due to this reason, the inner tip’s spring is remarkably weaker than the spring by which the shaft is loaded! So it is not sufficient to have the inner small tip touch the battery pole, apply enough force to get the shaft in contact, too.
Press POWER for the main menu. First you have to define the sorting criteria by choosing the menu item Grading Set (with RU you choose the menu item). Press POWER again to get into this item. With RU you may choose the criterion, change it with RR.
Leave the menu item with HOLD in order to store your changes. Leaving with POWER leaves the variables unchanged.
Go to Sorting Mode in the main menu. Confirm with POWER. Now the measurement can be started.
Afterwards, the counter can be reset in the menu item Grading Count.
1. Normal Mode -> Automatic measurement both of voltage and resistance
2. Sorting Mode -> Activates the sort mode
3. Backlit Set -> Set luminance, mode (ON, OFF, Trig) and delay before automatically shutting down in triggered mode
4. Auto OFF Set -> Variables which control the automatic shutdown
5. Grading Set -> Criteria for sort mode
6. Grading Count -> Sort counter
7. Calibration (to be evaluated still)
8. Factory Reset -> Recover -> yes = Reset, recover -> no = ESC (no reset)
9. Charge Set -> Setting the charge current for the internal battery
Have fun using the YR1030 and take good care!
