No, it will only work on a live outlet.
I suggest you disconnect all loads from your dead outlets, and then look at your breaker panel to see which breaker is tripped. The handle will be in an intermediate position between on and off. Push the handle off and then on to reset. If the breaker stays in the on position, the problem is in one of the loads. If not, you have a short in your wiring which should

Answer: 
I was intrigued by the question and did a test this way. plugged transmitter into outlet and knowing where the wire is in the room, tried to find it with the receiver. It does not work this way. Either the wire is too far away from the receiver or the + and - wires are side by side and cancels the signal.Sorry.

Rated 3.6 out of 5 by 86 reviewers.
Rated 1.0 out of 5.0 by Waste of money I read the manual and followed the instructions and the finder would either identify the wrong breaker or not pick up anything at all. I will have to get a higher priced unit that is effective enough to identify any circuits. July 7, 2016
Rated 4.0 out of 5.0 by Finder Worked as Advertised Works as advertised. Sometimes it's a little ambiguous but resolved itself on second or third try. Helps immensely when tracking down circuits and circuit breakers. July 2, 2016
Rated 4.0 out of 5.0 by good product good tool, work well, very good price. i recommend to every one. June 28, 2016
Rated 4.0 out of 5.0 by For powered circuits only Works great, but the circuit being traced to a breaker must be active. If dead circuit device is no good. May 23, 2016
Rated 5.0 out of 5.0 by Excellent tool to avoidhome electrical surprises I used this breaker finder on both a friend's home and my own. This helped to map the circuitry exactly as claimed. I am extremely satisfied. March 29, 2016
Rated 1.0 out of 5.0 by Did not work consistantly Tested the system on several outlets with known circuit breaker locations. Only verified 1 out of 4 tested. I re-read instructions several times and watched youtube video, and it still only worked on 1 circuit. February 26, 2016
Rated 4.0 out of 5.0 by Works well - if you just read the instructions I bought this 30 minutes ago and it took me just 30 seconds to find the breaker. I was hesitant about purchasing it because of a number of negative comments, but like I say in the review title "JUST READ THE INSTRUCTIONS !!". 1) It is VERY important that you not turn on the receiver until you get to the panel. 2) Slowly scan the ENTIRE panel, and IGNORE any beeps or the flashing green arrow the first time around... just continue your initial first scan. 3) Slowly scan the panel AGAIN, and this time when it beeps, you will have found the correct breaker. I suspect that the unit requires the first scan pass in order to determine the high/low range of signal strengths that it is receiving so that it can remember and then correctly identify the strongest signal the second time around. I've done the brute force thing before by just turning breakers off and on again, all the while running back and forth from the panel.... and then later have had to recover from all of the 'power interruptions' by turning my computer back on, resetting the clocks, etc... but I won't have to do that any more.
