Review on 🔧 DROK Small Digital Multimeter DC 6.5-100V 50A: Voltage, Amperage, Power Energy Meter for Precision Monitoring - LCD Digital Display by Keith Harris

This is for the 50A version with an external shunt on a plastic base, with separate holes to fix the base, to connect the power cables and connect the sensor cables. (The 100A version doesn't have an isolating base on the shunt, so you'll need to provide your own mounting base.) This is a fine meter, but it reads twice the actual current, and thus reads twice the actual power drawn. The meter is the same for 50A and 100A, only the shunt is different. Both shunts are designed to produce a measurement voltage of 75mV at rated load, so the meter simply converts the voltage across the shunt rather than measuring the internal current. If the two shunts are different and the meter is the same. well, 3 stars. UPDATE: After commenting below I found out how to change the scale. I hesitate to give all 5 stars because the docs say it is possible. However, the product page doesn't say there aren't ad and shunt compatible settings, and that's why almost everywhere in the "manual" says it's (only) 100A.
