Deal Details
KAIWEETS Smart Digital Clamp Meter with D-Shaped Jaws, Clamp Multimeter with Inrush Current Function, Auto-ranging Amp Meter Built-in HD Color Screen, Measures AC/DC Current Voltage Temperature NCV

$59.99 - 30% coupon (clip coupon) = $41.99

Upgraded intelligent Mode: We upgrade the amp clamp meter, which is unique in the market. The default intelligent mode when the meter is on can automatically identify AC/DC voltage/current, resistance, and continuity measurement signals, making the operation more convenient and safe
Advanced design & multi-function: The multimeter tester is built-in MAX/MIN、data hold、flashlight、auto-off features. D-shaped jaws can hold test leads and are more portable. It can measure AC/DC current/voltage, resistance, continuity, capacitance, diode, NCV, firewire, and temperature for all of your measurement needs
Large HD color screen: Easier to read than a traditional clamp meter. The HD color bright screen is good for working properly in dark places. Avoid reading the measurement value difficulty under direct sunlight. It is a good gift for friends and family
Self-test & inrush measurement function: The clamp meter automatically performs a self-test and displays "CAL" when it is on to ensure the accuracy of the measurement results. Also, Knowing the value of inrush current can help you locate a startup problem quickly, whether it's in the motor or in the starting circuit. Inrush current measurement range is 5-600A. The inrush function is only available in AC current mode, DC current does not have the inrush function

I prefer mechanical rotary knob, instead of a single button function (prone to failure). The sampling rate of inrush current is 100ms, par with multimeter with min/max function. The minimum identifiable DC current is 0.8 A, which makes it useless for checking dark current in automobile. Minimum identifiable AC/DC voltage is 0.8V. Again, not good enough for automotive troubleshooting.

Inductive clamp meter is OK for quick and dirty work. Use a decent multimeter with a shunt resistor in series if you need to accurately check high current. A 500 A shunt resistor starts at $15, and goes up to $200 for a 5000 A unit.

Some links to similar units but with the higher sensitivity for auto work as you describe? Thanks

Inductive ammeter devices are limited by physics, so they cannot achieve high accuracy at lower resolution. To accurately measure dark current draw from a car's battery, you'll need to attach a multimeter in series to capture the 8 to 15mA DC current draw when the car is in sleep mode. Some DMMs like the Brymen 525S or Fluke 87 can also capture 1ms data spikes.

Look for a 4 ch Rigol scope if you are serious about working on modern cars. The shape of the waveform is even more important than the displayed number. The yellow line shows the compression stroke of each cylinder during engine crank. Blue line is the voltage drop at the engine's ground cable. Older Rigol 1054 can easily be hacked to run at 100 MHz. No need to pay more for automotive works.
