Features: 

1. DUAL PURPOSE --- This meter can be used as a adjustable buck boost power supply module (PER mode) as well as a multi-function voltage current meter (VAH mode).

2. PER MODE --- when at PER work mode, it can convert DC 3.5V~12V to DC 1.2V~24V, and the power is 2W~3W.

3. VAH MODE --- when at VAH mode, it can be used as a multi-function voltage ammeter. It can be used to measure voltage, current, power, battery capacity and discharging time.

4. APPLICATION --- suitable for technical engineers to develop, debug instrumentation; aftersale engineers travel maintenance.

5. FEATURES --- dual operating systems; LCD high definition display; multi-parameter simultaneously display; over-power protection; 3 voltage input methods; power-off data saving; parameter calibration.

Description:

Two Working Mode:

1. Power Output Mode (PER) --- convert 3.5V~12V to 1.2V~24V.

2. Multimeter Mode (VAH) --- measure voltage, amperage, power, battery capacity and discharging time.

Application:

1. As USB buck converter & boost converter

2. As voltmeter

3. As ammeter

4. As power meter

5. As battery capacity tester meter

6. As battery load capacity detector

Using step:

1. Connect to power supply from input terminal;

2. Set work mode by keep pressing 'ON/OFF' for 10s;

3. Connect load or Device Voltage;

4. Rotate potentiometer to change output voltage if work in PER mode;

5. Short press 'ON/OFF' to switch displayed parameter;

6. Test and use.

Attention:

1. No reverse connection protection. Do not short circuit and reverse.

2. Adjust the working mode before using.

3. USB port can only input DC 5V. Need to input power from 'VIN+' and 'VIN-' if input 3. 5V-12V.

Package Included:

1x USB Power Module
