Description
The AstroAI AM33D Multimeter is designed to safely and accurately troubleshoot a variety of automotive and household electrical problems. It's easy and safe to operate and features many different functions for measuring current, voltage, and resistance, as well as continuity, transistor, and diode testing, which is both for automotive and household uses. Use this multimeter for: household outlets, fuses, wiring, general-purpose batteries, vehicle battery and charging system, automotive circuits and more.Note:
1. When the Meter is working at an effective voltage over 60V in DC or 30V rms in AC, special care should be taken because there is a danger of electric shock.
2. Before using the Meter, inspect the exterior casing. Do not use the Meter if it is damaged or if all or part of the exterior casing is removed. Look for cracks or missing plastic. Pay special attention to the insulation around the connectors.
3. If you have mistakenly connected the red test lead to the 500mA selection, then used this meter to test larger current(like 10A) or higher voltage, it might probably burn out the wires even the meter.
4. If you are the beginner, you should have known some basic physical concecpts and basic methods of using a meter, you also should have read the user manual carefully and known the consequences of misuse because any misuses will probably cause serious results.
5. This multimeter can not be used to test EMF.

Empowers You to Save Hundreds on Electric Bills
Electricity bills are rising. Now you can cut down on costs and find out what appliances are actually worth keeping plugged in. Simply connect these appliances to the Kill A Watt, and it will assess how efficient they really are. The large LCD display counts consumption by the kilowatt-hour, the same as your local utility. You can calculate your electrical expenses by the day, week, month, even an entire year. Also check the quality of your power by monitoring voltage, line frequency, and power factor. Now you will know if it is time for a new refrigerator or if that old air conditioner is still saving you money. Kill A Watt can help you reduce your power bill and will help find power-wasting appliances so you are able to decide whether it is worth keeping them plugged in. For standard 115 VAC appliances only, 15 amps maximum, 125 VAC maximum.Find Out How Much Electricity You're Using
 Large LCD display counts consumption by the kilowatt-hour |
Test The Quality of Your Home's Power
But measuring appliance consumption is just the tip of the iceberg. Because it can monitor voltage (Volt) and line frequency it can also test if an outlet is working, or evaluate the quality of the electrical power provided by your utility company. It can detect voltage drops around the house, help to predict brownout conditions or to make sure a new home's outlets are in working condition before escrow closes.
 The LCD shows all meter readings: volts, current, watts, frequency, power factor, and VA |

More detail please check the description picture.
Error Phenomena:
Due to the aging of the device and change of ambient temperature
1. the error becomes larger when measuring small current
Solution: When there is no load, short-circuit 2 pads of KEY and then power on, the module will automatically do zero calibration, after that shut off the module and cut the short circuit point.
2. the error becomes larger in whole measurement range
Solution: When connecting load(half of the range is best), keep adjusting R7 until it displays the same value with the more advanced calibration source.
Note:
If measure the current over than 5A for long time. please welding the wires to the meter port, to avoid High impedance and unstable working.
When the power supply is greater than 24V, please connect a 1k resistor in series to increase the reliability of the product
