## Questions & Answers

**Q: I am searching for current leak in a boat (12v battery).  Will this dial down to low enough amps to diagnose?  Thanks.**
A: Yes, the Innova is great for finding parasitic leaks in boats and cars. Turn everything off..... EVERYTHING and then disconnect the negative battery cable. Insert the meter in series with the neg bat terminal and the end of the cable. If there is a current leak it will show on the meter when it is set on the AMPS function. Becareful that you don't turn anything on when the meter is connected because the AMP mode is not fused. If a current reading shows on the meter start pulling fuses and disconnecting devices until the reading drops to zero therefore isolating the problem

**Q: Can I use this meter to test for bad circuit breakers at electrical panel or electrical outlets at home?  I'm newbie; want learn how to use.  Thank u!**
A: I would advise against it.  This is only a CAT 2 rated meter.  That means the internal safety features are not sufficient to handle the higher potential voltage and energy that could come about at a meter panel.  http://www.ni.com/white-paper/5019/enYou really want a CAT 3 meter if you want to measure any live breaker panels.If you are going to test for bad circuit breakers that are disconnected from the live wiring then you could use this meter to check for continuity and the like.  Do not use this meter on anything more powerful than a wall outlet.  CAT 3 meters are available for not much more money.

**Q: What's the lowest ohm reading it is capable of? 0.01? 0.1? 1.0?**
A: It may have 3 digits but it can not accurately measure milli-ohms, nor can any other meter that is not using a 4 wire probe setup and one that costs at least several hundred dollars. There is so much involved in getting milli-ohm accuracy I could write for hours, for example just the pressure and angle of your probes, the proximity of the wires to themselves, other metal object, flex of the probes, the fitting of probes in the meter, and thats just 1/10th of probe issues, then take in account of the power supply related issues, pcb design issues a to d conversions and no way can a 18$ meter give accurate or even relative accurate milli-ohm readings. It is just a common marketing ploy.

**Q: Does this unit have CONTINUITY testing to determine which are the traveler wires in a 3-way switch outlet? It has a HORN icon which looks like it would beep if continuity is foun (e.g. the travelers going from one to the next switch box) but I don't see CONTINUITY testing in the features list. Thanks!**
A: I don't know enough about residential wiring to answer your question, but yes, the HORN icon is what you select for continuity testing, and it beeps when the circuit is complete.

### ⭐⭐⭐⭐⭐ Review
*by G***S on 11 September 2023*

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 Amazon other than that of end user & customer.
