New Device Issues
Note before I begin. I am using a Fluke 77 DMM for voltage & resistance measurements, a signet 1202X-E DSO for for a reference ac signal (3 months out of calibration), and a TekPower PSU for sample dc voltages. I’m using an iPhone 6S with latest SW. The unit was never more than 12” from my phone.
My Pokit arrived physically undamaged. I removed the tape from the battery & reinstalled. On power up, it was unable to connect with the app. I checked the battery, which was good at 3.2 volts. I replaced the battery with a new one (also 3.2vdc) to be safe. Still no connect.
Next I checked the fuse, which ohmed out ok, and re-seated it. When I tried to reconnect, the app timed out. After several attempts, it connected. I unspooled the cables and first checked the temperature, which read 91.4F in a room at 68F (it’s been sitting at room temp for a couple of hours). OOPS.
Next, I checked the continuity against several resistors, but the reading is always ‘inf’, regardless. Even with the probes shorted, it reads ‘inf’. OOPS.
Diode continuity reads ‘inf’ regardless with probes shorted and open. OOPS.
On a 3.3 vdc supply, the device reads 0.00 mV. Same on 5 vdc. OOPS.
In the oscilloscope mode, a 1 v, 1 kHz square wave does not display at all. OOPS.
In the Devices window, I was prompted to update from FW v1.1 to v1.2. This completed successfuly. COOL!
However, at no time did the device list in the list of devices, though it appears below icon, showing the MAC address (90:FD:9F:32:47:91). Clicking the Find button has no effect. Clicking Disconnect results in a ‘Not Connected’ message, with the device now in the list of devices. However, clicking the name gives a ‘Connect Failed’ dialog box. After several retries, it was able to reconnect. OOPS.
I repeated all of the above tests with the same results. OOPS.
I removed the battery and gave it several minutes to do a hard reset. I reseated the battery and repeated all of the above tests with the same results. OOPS.
At this point, I think I have a bad device (I’m in the USA and shipping was several days), but I want to make sure I’m not missing anything. So:
1) any suggestions? and,
2) if it is dead, how do I exchange it?
Thanks in advance! -russg

Hi Russ,
The problem with Pokit measuring nothing is related to the fuse. When you removed and placed the fuse back in, it might have not made good contact. Please remove the fuse and make sure the cover clicks-in correctly and the fuse is properly pushed against Pokit PCB.
Let us know how you go.
Thanks

Good tip. I went back and tried all of that, and the fuse solder blobs are nice and shiny and the pwa contact look clean, too (I’m using a magnifier to check this. The fuse seems to be seated properly, though the fuse cover bulges (on both fuses) when it is in place. All four locking tabs seat correctly. So, I’m thinking it’s a mechanical or contact failure with the leads. I’m hesitant to strip it down completely.
Even if the fuse connection is bad, the temperature shouldn’t read 97F after sitting in a 68F room for 24 hours. Unless it’s on a chip, in which case it would just read the chip twmperature instead of the ambient. I don’t know where it is located, but I can’t imagine the desigers using chip temps for ambient measurements.
So, I’m back to thinking it really is broken.
I did try opening a ticket, but I’ve had no response at all. Does anyone know how I get a response from the support team? email doesn’t seem to work. I’d really like to resolve this and get a working pokit.
thanks -russg

Final update, I went back and gently sanded the solder balls on the bottom of one fuse flat, so the end tabs now click into the slots in the mother board and the fuse cover snaps into place without bulging. I get the same results (no voltage, resistance, etc readings) with the weird exception that the o-scope now displays a 20kHz square wave as a triangular waveform at 20kHz. So, I’m considering it defective and have shipped it back. I’m looking forward to receiving a working unit!

I just received my device, removed the paper insulator under the battery and did not work. I scraped the top of the solder blobs and the device is still nit working? The app has the message "Ensure your PockitMeter is powered up.." and that is far as I get after cleaning the battery contacts and restarting the app multiple times.
What now?

Dear all,
We have recently noticed that the BLE connection is not working properly on some Android devices. We forwarded this issue to our Dev Team and we are looking into this problem now. We will keep you updated as soon as we find the issue and release an app update to fix it.
Before asking you to return your Pokits, we'll ask you for a few days until we find the connection problem and solve it on the app.
Thanks and sorry for the inconvenience.
Cheers,

Has anyone heard from support?
I returned my Pokit for replacement (which was delivered about two weeks ago) but haven’t heard anything despite emails. I’d like to make sure it was received and not stollen off a porch and find out when my replacement/repaired unit will ship back.
I understand there might be delays - I really do want a working PokitMeter & I love the product - and I’m willing to wait but I also need a response.
cheers - russg

I am also struggling with getting any meaningful support. My Poikit appears to be dead-on-arrival and despite having raised three service request tickets and sending several e-mails, I am still not getting any replies. Having read through several threads in this discussion forum, I get the feeling I am not alone and perhaps Pokit HQ knows there is a fundamental issue with some units.... hence the silence....
