Digital Ammeter Voltmeter Coulomb Counter Wireless Voltage Current Tester Power Meter Bi-directional DC 0.01-120VDiagnostic-tool

This meter can measure DC voltage, current, power, charge and discharge capacity, watt, time and other parameters in both directions. With LCD display, several parameters displayed on the screen at the same time, is convenient for readings. At the same time, it also has many protecting functions, such as over-voltage protection, over-current protection, under-voltage protection, limit protection, etc.
Features:
LCD color display voltage, current, power, capacity and time, etc.
Several parameters displayed on the screen at the same time, easy to read.
Bi-directional measurement of the current, no need to change the wiring direction.
Wireless data transmission between the meter and measuring board, convenient for use.
Set each address individually, and view the measurement parameters from plurality of measuring board in one meter.
When use multiple machines simultaneously, the machine can be set individually for each channel to avoid mutual interference.
You can also use standard USB cable for wired communication.
With memory function when powered off.
Screen lock, timing off, adjustable brightness functions.
VAC-1030A equipped with relay to achieve over-voltage/over-current/under-voltage, limit protection, etc.
Suitable for monitoring the output voltage and current, as well as the battery charge and discharge applications.
Small size, light weight, convenient to carry.
Note:
VAC-1100A and VAC-4300A can also achieve the protecting functions like VAC-1030A's, but users need to buy the relay separately.
