pokitMeter: All in one multimeter, oscilloscope and Logger (Black)

I haven't purchased a phone in a while so my LG-V35 is only running Android 9. It still works great with this voltmeter/o-scope. I downloaded the POKIT app from the Play Store and installed in a few minutes. There's some instructions on how to set up the gizmo and that's it. I really am amazed at the size and portable nature of this. The little probes take a bit to get used to since they are curved to fit the case.I may pair this up with an old cell phone to leave at work for logging. It's really handy for that. For now I'm using it to monitor power in another room as I write some home automation scripts in another. I can get the phone app and see if my dimming routine is working or even just simple on/off functions. Saves me a lot of getting up and walking. Perhaps too much since I've started to gain weight...

i bought this as a very portable SMD repair multimeter and it does everything great but the diode mode only shows 1 or OC nothing else and it would be perfect if it showed voltage drop and thats something you need for diagnosing caps and inductors, i just really hope they would add it in a firmware update. and its really nice for the continuity sound to go through headphones especially because i share an office with 2 people and i do all the chromebook repairs and its nice to not have beeps going off every 3 seconds and annoying everyone when i do have to bust out the multi.

I've been following the pokit team for a while, mostly for the Pokit Pro multimeter in a pen. I wasn't aware of this product until I saw it offered on Vine, so I grabbed it to see what it is all about. I've only used it sparingly, but it seems to have a lot of capabilities that I don't have opportunities to explore just yet. It looks well built, and the company seems interesting; so I'll keep looking for a chance to give this thing the once-over.

Works very well for my low voltage needs. Once it has an interface on iWatch it will be perfect. Not replacing high end precision equipment, but it does so many things well. Have a low band witch scope, multimeter and data log always on your keychain is pretty nice.

GENERAL COMMENTS:The piece of paper that comes with the Pokit device is called a “user manual”, but it’s a single sheet that only covers the installation instructions. It doesn’t give info on how to use the app or how to replace the fuse. When I installed the app I had to check a box confirming I read the manual which is frankly silly since there’s hardly any information there. I assume their motivation is to limit liability since the “manual” prominently displays a “Warning 60VDC Max” warning. The box only included one fuse, not two as advertised.I had trouble with the app on an iPad Pro, IOS version 15.4.1. I repeatedly got a popup that read: “POKIT app, No devices found. Tap button on Pro device to wake.” Since the device I received is not the pro version there is no button to tap. The interface shows a large round button near the bottom of the screen when you want to take a measurement. It frequently grayed out and the app froze. I had to reset my iPad to restore functionality.My chief interest was in the product’s oscilloscope function. However, the measurements I made during testing were sometimes very inaccurate, and the lack of a continuous display (snapshots only) is of no use to me. In my opinion, this device is useless as an oscilloscope/spectrum analyzer, and is OK as a multimeter. The only advantage it may give is the capability to make measurements at a distance (within Bluetooth range), and tracking voltage, current or temperature changes.Detailed review of each function below.OSCILLOSCOPE:The Pokit is very hard to use as an oscilloscope or spectrum analyzer. When changing the input signal you sometimes have to try a few times to get the correct signal display. If you are not aware of what it should look like, you may make mistakes. Also missing is the frequency and voltage display as text, rather than having to use the grid. The worst drawback is the lack of continuous display, rather than just snapshots. This deficiency makes the product useless as an oscilloscope and spectrometer. Neither the manual nor the app’s user documentation specifies the bandwidth of the oscilloscope. This standard specification is vital information.I connected the Pokit to an LF signal generator, in parallel with another oscilloscope to compare results.When opening the 'Mode' for Unit and Frequency selection, the Frequency selection alwaysjumps back to 500kHz, rather than stay on the previous selection/setting. When you start the oscilloscope, the screen first flashes a white grid on black background and then quickly changes to white background. I could not find a “dark mode” to bring back the black background. Sending a 1kHz sine wave from the signal generator correctly shows 1mS period. The pp amplitude looks OK (not able to evaluate the accuracy), but it would have been nice if the signal frequency and amplitude values were displayed in text on the screen.It is nice that you can change the time/div and volt/div by dragging with 2 fingers on the touchscreen, but the wave tends to disappear to the left of the grid when trying to squeeze the waveform.The signal displayed a correct sine wave when I changed the input signal to 100Hz, but when I changed from a 100Hz sine wave to 100Hz triangle wave, not changing the POKIT app settings resulted in a waveform appearing to be of much higher frequency. It shows a 304mS period instead of a 10mS as it is supposed to be. It did not change when I tried to press the “take measurement” button. When I tried to change the mode setting the app froze and I had to reset my iPad. Redoing the measurement then with the same input correctly showed a 10mS period.Changing the input signal to a 100Hz square wave resulted in a deformed top and bottom waveform, even though it showed correctly on the oscilloscope I compared it with. Again I tried to press the “take measurement” button to change the display but it didn’t. Changing the time/div setting from the 'Mode' menu also didn't change the waveform, hence displaying incorrect values. Using 2 fingers on the touch-screen to change the time/div changed it, but not to the correct value. The square wave showed approx. 5mS period when it should have been 1mS.MULTIMETER:-Voltmeter: Display shows the voltage continuously as expected. I compared the Pokit’s reading to a device I trust and found the measurement was inaccurate. My trusted device measured the voltage as 10.00V DC while the Pokit displayed 10.13V.-Ohmeter: Measurement was off. Trusted device showed 147 Ohm, Pokit was off by 2 Ohm at 149. A 10 Ohm resistor measuring 10.1 Ohm on my trusted meter flickers between 9.77 and 9.85 Ohm on the Pokit.-DC current and Continuity: Looks OK, showed the same result as my trusted multimeter.-Diode: Using an LED does not result regardless of direction in any display Just stays 0C. Using an F922 diode it show 1 in one direction, and 0C in the other direction-AC voltage: Looks OK, with the same slight difference on my trusted meter as DC Min AC does not work until after you press reset. Max voltage ok.-Thermometer: Looks OKLOGGER:This looks like a feature not found on most other multimeters. Only useful for tracking voltage/current/temperature changes, but it is inaccurate and too slow. It does not support tracking resistance changes. Changing the sampling interval while logging doesn’t change the display. Just shows the noise switching x10 on the tone generator.

I was pretty annoyed with my old multimeter/oscilloscope. The batteries were hard to replace, it was bulky and it had a really unintuitive interface. Most egregiously, it would give false negative readings in connectivity mode when the batteries were low. It didn't even have a low battery indicator.Pokit is super small and pretty convenient. I have some peeves which I think prevent it from truly replacing the one on my workbench.1. It is annoying that I need a phone/tablet at all times, even for the most simple functionality. I think that at least basic things like connectivity checking can be done with an on-device beeper and a couple of seven-segment displays.2. The oscilloscope has no continuous logging mode. I need to keep pressing a button to refresh the displayed signal. I hate having to keep changing hands when poking at a breadboard.3. The provided clip-on ends are great. A way to keep them attached to the device would make it even better. Perhaps a slot on the back?4. There is no mute button in the app. This means I have to manually keep my volume low or disconnect my headphones if I don't want beeps.5. Most egregiously, there is no desktop app. It's literally an afternoon's worth of work to recompile the iOS app for Mac. I feel ridiculous having to keep a phone on a stand at a desk that already has a laptop on it.

This is by far the smallest multimeter I had ever used! It is accurate to a point, but for it's size it is perfect for when you just need to get a few readings when doing some on the fly testing or when you are away from your shop what your more accurate gear like 3D printer meet-ups. It's very small, and you could just have this on your keychain in case you need it when out in the field or as a very good backup incase your main one is just giving you wrong readings. This would be a good 2nd reading as a just in case your other meter is a bit off or to verify voltage is correct.
