BSIDE ESR02 Pro Digital Transistor Test Table M328 Resistance Inductance Capacitance ESR TesterFeatures: 1. Add startup voltage detection function 2. Automatic detection of NPN and PNP transistors, N channel and P channel MOSFETs, diodes (including dual diodes), thyristors, transistors, resistors and capacitors, etc. 3. Automatically test pin elements and display on LCD 4. Reference for transistors, MOSFET protection diodes, and amplification factors that can detect the forward bias voltage of the transistors emitter. 5. Measure the gate
Features:
1. Add startup voltage detection function
2. Automatic detection of NPN and PNP transistors, N-channel and P-channel MOSFETs, diodes (including dual diodes), thyristors, transistors, resistors and capacitors, etc.
3. Automatically test pin elements and display on LCD
4. Reference for transistors, MOSFET protection diodes, and amplification factors that can detect the forward bias voltage of the transistors emitter.
5. Measure the gate threshold voltage and gate capacitance of the MOSFET
6. 1602 liquid crystal display adopts LCD (12864 liquid crystal backlight)
7. Fast test speed, effective component test: 2 seconds (except for large capacitors, it takes a long time to measure large capacitance, and the measurement time is one minute is normal)
8. One-click operation, boot test, one-click acquisition
9. Power consumption shutdown mode: less than 20 nA
10. Automatic shutdown function to avoid unnecessary waste, save battery power and improve battery life
Specification:
1. Two-button operation, automatic shutdown
2. Only 20na off current
3. Automatic detection of NPN, PNP bipolar transistors, N-channel and P-channel MOS field effect transistors, junction field effect transistors, diodes, diodes, thyristors, low power unidirectional and bidirectional thyristors
4. Automatically identify component pin arrangement
5. Measurement of Bipolar Transistor Current Amplification Factor and Base-Emitter Threshold Voltage
6. Identification of Darlington transistor by base-emitter threshold voltage and large current amplification factor
7. Detects bipolar and MOS transistor protection diodes
8. Gate MOS FET threshold voltage and gate capacitance measurement
9. Two resistances and resistance symbol display can be measured simultaneously. The decimal value shown on the right is 4. The resistance symbols on both sides show the number of pins. So you can measure the potentiometer. If the potentiometer wiper is not shifted to the extreme position, we can distinguish the middle and both ends of the needle
10. Resistance measurement resolution is 0.1Ω, can measure 50MΩ
11. Can measure 325pf-100mf capacitor with 1pf resolution
12. 2uf more capacitors can measure equivalent series resistance at the same time. Two can be displayed as decimal values ??with a resolution of 0.01Ω
13. The two diodes can be displayed with the diode symbol in the correct order, and the diode forward voltage can be given.
14. The LED was detected as having a higher diode forward voltage. The combination of LEDs is identified as two diodes
15. Can measure a single diode reverse capacitance. If the bipolar transistor is connected to the collector or emitter of the base and pins, the collector or emitter junction reverse capacitance can be measured
16. Can be connected with single measurement rectifier bridge

One of the best dog toys I’ve bought off Amazon in a long time
Color: Green
My dog Rosie is a heavy tower so it is difficult to find balls she doesn’t destroy quickly. I came across this item on Amazon and it is honestly one of the best pet toys I’ve ever bought on Amazon. After a long day of work sometimes I come home and Rosie has a lot of energy. I turn this ball on fast mode and she has so much fun. I do worry about how much shaking in her mouth. I don’t wanna give her a headache, lol but there’s also a slow mode that you can press for the ball to slowly move around, but it’s a really good toy and I’m happy. I purchased it if you have a heavy tower, I wouldn’t worry about them breaking it because we’ve had it for a couple weeks now and she’s doing great.

Not indestructible, but dogs love it
Color: Green
My dog LOVES this toy. Unfortunately, she loves it so much she destroys it. I have now purchased FOUR of these, but if left unattended for 5 minutes, my American terrier breaks this apart. She loves it so much though, I keep buying replacements. This is a wonderful enrichment toy, but you must keep an eye on your toothy friend.

Engaging and Fun, But Lacks Durability for Strong-Gripped Dogs
Color: Green
The internal mechanism of this toy works very well, and the ball’s movement immediately caught the attention of my Boxer pup. He was absolutely fascinated and spent hours each day playing with it. However, while the toy’s design is engaging, the durability of the exterior leaves much to be desired—especially for dogs who tend to pick things up with a firm grip.
We didn’t know what to expect since our pup hadn’t previously played with an interactive ball, so we supervised playtime and made sure to store the ball in a safe spot when we couldn’t keep an eye on him. Despite this, the ball didn’t hold up. Our pup wasn’t intentionally chewing it. He simply carried the ball in his mouth when we moved downstairs or to another room, yet the grip while he carried the ball caused significant damage to the exterior. Within about a week of regular use (approximately 40 hours in total), the ball’s outer layer became deeply gouged by his teeth.
To clarify, my pup wasn’t biting down hard or trying to destroy it, but his natural grip while carrying the ball left deep grooves in the surface. In just days, these gouges made the exterior sharp to the touch and compromised the structure. By the end of the week, we couldn’t screw the cover back together after removing it to recharge the ball, which made it unusable. And I was dismayed that there aren’t replacements readily available.
Overall, my pup absolutely loved this toy — it was engaging and kept him entertained for hours. However, if your dog has a strong grip or frequently carries toys in their mouth, this may not hold up as well as expected. It’s a great concept but needs a more durable outer layer and replacement hard covers to make it a long-term investment.

My dog loves this ball
Color: Green
The battery on this lasts forever. The random on/off motion and when it gets touched inducing motion just keeps my dog guessing and occupied for a long time. My dog's tail is wagging the whole time.

Great ball
I have bought two of these in different colors. My Yorkie loves them. They’re very interactive even if you don’t put the cover on it they move and if he’s not playing with it, it tends to go into sleep mode.My Yorkie got the cover off the ball within the first two minutes. But he loves the ball. Now bought 2nd ball. The ones with covers don’t work he rips the covers off.
