Odd they don't provide even basic details about these two meters.
They're not selling to electronics engineers. Car mechanics just want something that "works".
With such loose use of the word, "works" means very little to me anymore.
Had someone ask me about a current clamp to measure the parasitic draw when the car is off. I have found the UNI-T UT210E works good enough for this. They mention making this measurement with this meter. Anytime I have used a standard handheld to measure this with a shunt or direct, I have to add a bunch of jumpers to allow me to pull the battery terminal after the car starts powering down. I wonder if this meter has a better way to make this measurement. Doubt it.
I would have said that a multimeter with an amps range and no current clamp is a very bad idea for a car mechanic, that's just me though.
How long before they try to measure current draw on engine start?
I am not a mechanic but dabble a bit helping friends trouble shoot as well as working on my own. Normally, 2000 counts, back light, resistance up to 100K, ability to zero the meter, DCV/mV is about all I need in most cases. Parasitic drain comes up from time to time and I have used the built in shunt to make the measurements. Temperature is also handy. Because of how I abuse these meters and the very limited feature set, $50 is about all I would spend on one. I don't need RMS, and the Fluke 17B+ would be a big step up.
Beyond this, I like some of the meters that can measure injector pulses, timing, RMS and such. I've looked at a few and would really like the little Brymen except for the fact that they don't save ALL of the settings. The other problem is the amount of noise in the system is high enough to cause even the Brymen to give intermittent readings. I looked at a low end automotive meter that actually looked pretty decent but had IMO a design flaw. It appeared the designers didn't follow the data sheets. That meter was very sensitive to noise and would constantly reset.
Having a portable scope has came up as well. I have a friend who was wanting to watch the cranking current to check for weak compression. A good job for a scope. I just measure it directly.
If I thought there was a chance the would implement any suggestions I made to improve this meter's sensitivity, I would have reached out to them.
