User questions & answers

Question:	which setting is for volts, and which is for ac
Answer:	The V with the two lines is DC volts and the line with the squiggly line is AC volts.
Question:	is the continuity test audible
Answer:	Good question. and I can't find an answer it doesn't say but in the picture when it's showing someone testing continuity it shows that it's beeping what it doesn't say that it does beat and we've got two people on here that say it does not and two people that say that it does so good luck I'm looking for one that is audible myself why all multimeters don't have an audible noise when you have continuity I will never know either that or you can have one that has a paper thin needle that jumps and you can't see it and you have to take your eyes off of what you're working on to see if you have continuity and when you move your head you lose contact and it's such a pain in the ass
Question:	Is this unit protected by a fuse? If so, is it replaceable? My last meter was fused but it was soldered. I couldn't easily replace it
Answer:	I had to replace the ammeter fuse (because I forgot to switch the hot (red) test lead from the left side to the middle, before testing my car's battery voltage). That fuse is 10A 600V. I looked around for those & couldn't find them, but found 10A 250V and these worked OK. They're 20 x 5 mm ( .2 x .79") ceramic fast-blow. https://www.amazon.com/gp/product/B07JFDTTMJ/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
Question:	Can this handle being plugged into a wall socket? Also, can someone give a walkthrough of how to safely test a socket
Answer:	plug the red lead into the meter socket marked COM and the black into the center meter socket. Set the dial to V~ (for AC volts) on the 200 scale (for household current) insert one probe lead into each of the wall socket's vertical slots and move them around a bit inside the outlet slots to make sure you're getting a good connection, if in doubt plug a lamp or something into the socket. If you suspect the outlet socket itself has failed carefully remove the wall plate in order to access the actual wires connected to the outlet to be sure it's either a dead circuit or the outlet itself has failed.

User questions & answers

Question:	Does the volt meter itself ever need recharging
Answer:	You have to replace the battery at some point!Maybe soon if you leave it on!
Question:	could this measure down to say 0.1 ohms
Answer:	If you really need to measure extremely low resistances accurately, you can get a power supply that you can set for a constant current of 1A, and put it through your test load. Then put your meter in the DC millivolt range and read across the load. It will display the resistance in millohms, so a reading of 100 mV would correspond to 0.1 ohms. Few people need to measure such small resistance values, but some specialized things like coils and inductors have test specifications down in those ranges.
Question:	Help. i have a short or bad ground somewhere in my automobile, battery and alt new - i think wires going to the pcm. will this help identify? thanks
Answer:	This is called a parasitic draw and a multi step process can isolate it down to a single component. You start with checking the draw on the battery. Remove the negative terminal and set the meter to 10 AMPS with the black lead plugged into the the COM connector female on the bottom and the red plugged into 10 amp female on the far left. Clamp the black lead to the negative battery cable connector that you removed and touch the red lead to the negative terminal. If you get a reading higher than a quarter of an amp you the battery is discharging and depending on the draw it will run down over night. A tip: Make sure everything is off in the car by closing the doors and removing the bulb from courtesy engine compartment light. If the bulb is inaccessible just duct tape the switch down. Also if you entered the car to pop the hood you should wait for the computer to go back to sleep - about 20 minutes - before running the test. If there is a draw you should start isolation by pulling fuses - when you pull the right fuse the reading will drop to 1/4 amp or so. The fuse fronts a wiring harness bundle and you can see what circuits it is protecting on a schematic - first thing to check are switches on the bundle and any after market additions to the harness. Most times it will be an open switch but a poor installation of additional lights or accessories is also a high suspect spot for a short. If a switch replace it or even just open it (turn it off). If a short you need to isolate the individual circuit on the harness bundle. Short isolation is a difficult time consuming task and rather than describe it I recommend that you watch this video on YOUTUBE. It is the best I have found for going all the way to the source of a short. Second tip is to have a helper with the fuse pulling and remember that some vehicles have 2 or 3 fuse boxes. GOOD LUCK, this is time consuming but not rocket science. https://www.youtube.com/watch?v=q5zLxD74r20
Question:	Does it have a beep function to check connections
Answer:	If you're referring to the Testing for Continuity function -- yes. "The buzzer sounds if the resistance of a circuit under test is less than 70 ohms".

Fuel Injector Test

FUEL INJ = Fuel Injector Mode is specifically set-up for fast and easy injector circuit diagnosis. One quick connection to the circuit and the Power Probe IV will display all the needed fuel injector testing information that would normally require using an lab-scope.

Fuel Injector Test (Continued)

ON- ms = Injector Pulse On-Time (milliseconds) - This is the total amount of time that the fuel injector is energized and supplying fuel to the cylinder. This can be compared to scan tool PID data to see if commanded on-time equals actual on-time.

2 IND-K V = Inductive Kick Voltage - Normal inductive kicks range between 55 and 90 volts. You should see a similar voltage number from each of injectors on the engine. Note: The height of the inductive kick is sometimes cut-off by an internal ECM diode to about 35 to 45 volts. Note: This test does not apply to hi-pressure injectors used on diesel engines and gasoline direct-injection en- gines.

3 ECM V = ECM Ground Voltage - The engine computer activates each fuel injector by com- pleting the ground circuit with an internal transistor switch. When the fuel injector is energized, the ECM ground voltage should be close to zero volts. Actual measured ECM ground voltage can vary, and may be closer to 0.5 volts because of the internal resistance of the switching transistor.

4 INJ V = Injector Supply Voltage - This is the battery power being supplied through the fuel injector itself. Measured voltage should be close to full battery voltage. There may be small volt- age drops in the circuit, however, anything more than 0.5 volt loss from the source battery voltage should be investigated.

Feed Test

FEED TEST - Power Feed Test (PFT) is a powerful feature primarily intended for testing power or ground feeds. PFT places a small current load (30 milliamps).

on the circuit and will safely load circuits during voltage and ground testing, while at the same time providing an accurate resistance reading of the circuit you are testing.

Loading the circuit provides more reliable data and can quickly identify circuit weakness caused by damaged or corroded wiring or connectors that normally can’t be found using a static voltage check.

Voltage Test

VDC mode is for testing DC (direct current) voltages. Voltage testing is as easy as contacting the probe tip to a circuit and reading the display. The Power Probe IV will display the probe tip voltage in the center display.

The Power Probe IV automatically enters VDC Mode when first connected to the vehicle’s battery, or to a 12-24 volt power supply. VDC Mode is the only mode that the Power Probe IV can supply battery power or ground by pressing the rocker switch.

If the Probe tip voltage is within 0.5 volts of the source battery voltage and the circuit resistance is less than 10 Ohms, the Red LED will illuminate and if the speaker is turned on, the speaker will make a high-tone.

When testing on ground circuits, as long as there is less than 10 Ohms total circuit resistance from tip to battery ground, the Green LED will illuminate and the speaker will make a low-tone.

User questions & answers

Question:	Is the unit truly auto-ranging? i see a "range" button on the unit pictured
Answer:	Yes
Question:	What batteries does it use
Answer:	9v battery. It does come with it. You will have to install.
Question:	For a hobbyist, why would I not buy a $20 multimeter vs something
Answer:	Fora hobbyist the really cheap meters are the best because sooner or later one will test something that will ruin the meter. This meter is really an intermediate meter which is above the hobbyist stage but still below the professional stage. An no, buying a Krug doesn't make you a professional.
Question:	Does continuity test produce a beep
Answer:	Yes. Turn dial to diode setting and press FUNC once. Beep is plenty loud. Great meter for the price.
