This meter has an input impedance of 10 MΩ when reading voltage - which can be good, if one is reading the voltage across components on the "circuit board" of a working electronic device!I do find the low impediace feature very nice....but your not going to get that untill up in the more expensive units....plus you can always use a cheap analytic meter or a low voltage light bulb in case you runi into ghost voltage. I guess I like the low impediance feature as my kids in Cali runi into old wired homes that tend to create greater ghost voltage issues.
I should have read the entire spec sheet.Do note the comment of MTN REMODEL LLC at Post #11

What MTN REMODEL LLC means is that you do not get the option of having a "Low Impedance" for reading voltages built into a Digital meter until you get to higher priced models!
When measuring voltages in "House Wiring" with a High Impedance meter (such as this), you are likely to have the meter "read" voltages which are there but are not able to produce any significant current across lower impedance devices - such as light bulbs.
These voltage readings are often termed "Ghost Voltages" (or Phantom Voltages) and are caused by induction, leakage etc.
A meter having a (relatively) low impedance, such a "cheap" analog meter, will provide a "drain" on these voltages and NOT "read" them - or, at least, indicate a much lower voltage than would be "read" by a "High Impedance" meter.
Hence, if you do have a need for a meter such as the "Klein model# MM400" , buy it.
However, if you do not wish to "muck about" with additional "shunts" when measuring voltages in "House Wiring", you should ALSO obtain a "cheap" analog meter - such as this.
This meter has an impedance of 2 kΩ/Volt.
Hence, on the 250 V scale, its Impedance would be 500 kΩ (or 0.5 MΩ)
If you are going to use the meter only for "automotive and home electrical testing" (initially), it would probably be better to purchase a (cheap) analog meter - such as the above - and a (cheap) digital meter, such as 7 Fn Digital Multimeter AC DC Voltage Volt 10 Amp Current Resistance Ohm Meter | eBay - for more "precise" readings - for a total of about $16.00
If you find that you do "need" it, the "Klein model# MM400" could come later and you would have gained experience for only $16.00.
(Also, if you happen to damage either of these lower priced meters, you would be "down" only $8.00 or so.)
Totally. Within your budget. Getting a separate amp clamp may be a lot cheaper then a combo piece. I only mention it, on case you find a good deal somewhere.I think there is an argument for not spending too much as a beginner. Maybe I can compromise between the two options.
