## Description

Innova 3300 Hands-Free Digital Multimeter Black

Review: Great tester. - This is nice. It’s small enough to fit in my drawer. Great value for the money. Tests great and works well.
Review: Model 3300a. Inexpensive. Well Built. Accurate. Fits in a Shirt Pocket. No Amps Functions. - I'm an engineer with access to a high-precision certified calibrator and decided to evaluate the Innova 3300a. It is one of thinnest, smallest, flat form-factor Volt-Ohm meters available. It easily fits into a shirt pocket (see picture). There is no case or cover over the display. The probes are permanently attached, but the connection seems sheltered by the wrap-around cable storage channels with probe clips. The probe tips have removable protectors for crowded test points. (See Picture) Also, it is easy to unfurl one lead and use the other while still stowed away snapped to the meter; or one can use both leads while the meter is held to your wrist by elastic bands. So, overall my first impression is that it is an improved design for a small volt-ohm meter. But, is it accurate? My old mini-meters are more guesstimate devices than measuring tools. The meter functions are Volts (AC & DC) and Ohms with the related diode (Applied voltage below 1.000 VDC) and continuity functions (beeps when resistance is below 60 Ohms). There are no functions for Amps, frequency, min/max, duty cycle, temperature, battery check, or anything else; just Volts and Ohms. However, Volts and ohms solves an amazing number of problems when troubleshooting. (And you could use a tiny amp probe or a shunt for amps if really needed.) The 3300a is low priced, with specifications typical of low-priced meters. I didn't expect much. However, it also is far more accurate than advertised. The specifications are a basic DC accuracy of 0.8% of Reading plus 5 least significant digits or counts (0.8% rdg + 5 cnts). I tested every range (200mV, 2V, 20V, 200V, & 600 VDC) at 10% and 95% of range. The worst DC error I observed was 0.3 mV at 190mV (that's 3 counts or 0.16%). ALL of the other DC test points were off by 1 count or less! (See pics at 12V and 1.5 V, common battery voltages) I tested in a similar fashion every Volts AC range at 50 & 60 Hz. Volts AC had more error than Volts DC, but none observed more than 7 counts with 120.0 VAC indicating 120.3 (3 counts) and 240 VAC indicating 238 VAC (no decimal place, so 2 counts error). There was no difference in measurements observed between 50 & 60 Hz. Resistance measured 3 counts high near the max of each range and better closer to 10% of range. The specification is (1% rdg + 5 cnt) but the actual performance was about (0.1%rdg + 1 cnt). The diode function seemed to have a bit more error than DCV, but was well within specification. (See Picture of 0.900000 V feed.) In summary, this is a delightful find - Inexpensive, well built, accurate, easy to carry and easy to use. I am ordering 3 more as gifts, and one for my desk. Disclaimer: I bought and paid for this myself. All statements are my observations and my opinions about the model 3300a, Lot number 220701 delivered to me - yours may be different. I have no relationship with the manufacturer, seller, or desertcart other than that of end user & customer.

## Questions & Answers

**Q: I own an Innova 3300 that over estimates voltages, 9V PS reads 10.5, 12V reads 13.8, 3.7V battery reads 6.24 what can I be doing bad??**
A: A 12 volt car battery when fully charged is 12.6 to 12.7 and reading of 12 volts is considered dead. AGM batteries read a little higher

**Q: Can I use this to test the thermal fuse on my dryer?**
A: Yes, I recently used it to test a thermal fuse in a popcorn maker.

**Q: Is this sensitive enough to allow me to determine the voltage on my doorbell wiring (16 volt vs. 10 volt vs. dead)?**
A: Yes!  My son used it for a science project that measured the amount of electricity fruit generated and it worked wonderfully.

**Q: what kind of battery does it use?**
A: Standard 9V rectangular battery with snap on connections

### ⭐⭐⭐⭐ Great for the average homeowner
*by P***K on March 18, 2013*

I really like this little device, price considered of course. I wouldn't expect it to be as dead-accurate as pricier models, so for true contractors/electricians/repairmen, this is at best a backup unit, but for the average homeowner this is a pretty nice little device. I've used it to check Ohms on speakers (they did fluctuate so I doubt it was completely accurate, but gave a general guideline at least), as well as to test for which line is "hot" while replacing a lightswitch with a timer lightswitch for our exterior lights. Our lightswitches use the two-blacks and a neutral, so it's important to identify which black is hot so the item isn't damaged (and also for safety to ensure the correct circuit is off). So, for the homeowner who's looking to do some mundane testing, making sure electrical lines are safely off, those sorts of things, this device seems very solidly built, and while perhaps not accurate for precise measurements, seems accurate enough for many uses (our AC line read at 122 volts for example). Also, the instructions aren't clear on how to use the device, but basically you use the red prod to connect to hot for testing, and the black to connect to ground or neutral (in case, like me, you don't know the basics of how to use a multimeter); for standard outlet AC testing, just turn the dial to 200 on the AC voltage setting. You can also watch some instructional videos on YouTube. The display is very clear and powers on instantly; it uses a 9v battery so it should last for a while. All in all, I like the device, it was very affordable and works well for my purposes. And of course, always be safe when working with electrical!
