Frequently Asked Questions about The Inspector USB / Search for more FAQs in the search field above


When I put the Inspector USB in total mode, it does not accumulate the total counts.

The latest version of the Inspector USB requires that the timer be set prior to accumulating total counts.

Can I power the detector with just the USB without a battery?

Yes. The unit will run with a standard miniUSB plug and AC adapter.

How many data points can be stored in the internal memory of the Inspector USB?

Total 1356. At 1 minute intervals, that's 22.6 hours. At 10 minute intervals, that's 226 hours (9.4 days) At 1 hour intervals, that's 1356 hours (56.5 days)

How do I power The Inspector USB?

The standard means is a 9 volt alkaline batter, There is no issue with using a Lithium 9 Volt battery and you can power The Inspector USB via the USB port and a standard USB-AC adapter.

When I put the Inspector USB in total mode, it does not accumulate the total counts.

The latest version of the Inspector USB requires that the timer be set prior to accumulating total count.

To take a timed count, follow these steps:

1. With the Inspector operating, set the Mode switch to Total/Timer. The display shows 0 and Total in the upper left portion of the display.

2. Press the SET button on the end panel to set the time for your count. You will see the hourglass, and the most recent timing period used. The first time you use the timer, the setting is 00:10 (ten minutes).

3. Use the + and - buttons to set the timing period. The timed period can be for 1 to 10 minutes in oneminute increments, for 10 to 110 minutes in 10-minute increments, or for 2 to 24 hours in 1 hour increments.

4. Press the SET button. The Inspector starts totaling the counts it registers, and the numeric display is updated each time a count is registered. The hourglass indicator flashes during the timed period. During the counting period, if you want to see how many minutes remain, press and briefly hold the SET button. The display counts down from the time setting in hours and minutes to zero. For example, if the display shows 00:21, then 21 minutes remain.

5. At the end of the timed period, the Inspector beeps 3 times and repeats the beeping 3 times. The number displayed is the total count and the hourglass will stop flashing.

6. To find the average dose rate for the timed period, divide the total by the number of minutes. The average count is in counts per minute. To convert to mR/hr for Cesium-137, divide by 3340.

7. Move the Mode switch to one of the dose/rate modes to return to normal operation. If you move the Mode switch to one of the dose/rate modes while the Inspector is taking a timed count, the timed count will continue.

8. To reset the timer to take another timed count, press the SET button to set the time for another count.

9. Press the SET button a second time and the Inspector will start totaling the counts it registers, and the numeric display is updated each time a count is registered.

5.0 out of 5 stars Inspector USB a serious upgrade from previous versions, October 8, 2013

By Concerned Citizen

This review is from: Radiation Alert Inspector USB Handheld Digital Radiation Detector with LCD Display (Misc.)

The Inspector USB is the newest version of The Inspector radiation detectors. It's essentially a Geiger counter, but the numerous features puts it far beyond the "lunchbox" luggable models of yesteryear. I used the previous version (Inspector Plus) and loved that I could get so much out of something that fits in a large coat pocket. This unit has the same 2 inch "pancake" tube as the older versions, but now they've stepped it up a bit with the addition of on board memory, built in efficiencies, and free (Let me say that again, FREE!!!!) Observer USB Software. I liked the previous version quite a bit, but I straight up LOVE this one.

I'm able to set the time and date and download all of my surveys to my computer and open them up in Excel. I did have some trouble doing this at first because the data logging isn't turned on when you get the unit. You have to go into the Utility Menu, set the time and date, and then turn on the recording feature. Once I got that going, I was off and running.

One thing I really like about this product is the ability to take timed counts. I can establish background radiation levels much more accurately with this and, if I used a wipe test plate, I would be able to take timed counts with swipes and what not. With the older versions, you have to attach these metal rails to the back of the detector before you can use the wipe test plate, but this version had the groves for capturing it built right into the back of the enclosure.

Given that I don't use the wipe test plate, I opted for their "Xtreme Boot", which is a rubber overlay that adds a bit of protection for the instrument. The big end window on the back of the detector is great for detecting alpha (it does beta, gamma, and x-ray too) and adds greater sensitivity than smaller GM tubes, but it can be fragile and this boot does a great job of protecting it when I'm carrying it around with me. I found out after buying this that Amazon sells it with the boot, but calls it the "Inspector Xtreme USB". I ended up paying $10 extra because I got them separate, but you can save a few bucks if you buy them together.

The software was easy to use. Once I installed it, all I had to do was plug in the unit with the USB cable and a window popped up and started collecting the readings coming from the detector. I retrieved the data off the unit, but I can also save the live readings I'm getting while the unit is attached to the computer as well. I can change settings and, if I use the efficiencies, I can customize each of the settings for each, which essentially makes it so that if I know what isotope I'm surveying, I can plug in my own settings if that one isn't already listed. It wont change the icon on the display though, so if you do that, be sure to remember which one you changed so you know which one to select.

All in all a great unit. I'm impressed! Looks a lot like the other versions of The Inspector and other models that attempt to copy it, but this one is clearly the beefiest of the bunch.
