Features and specifications

Key features:

• 128 x 160 TFT color display
• Powered by 9V battery (battery not included)
• New boot voltage detection
• Automatically test the pins of a component and display on the LCD
• Measure the gate threshold voltage and gate capacitance of the MOSFET
• Measure bipolar transistor current amplification factor and base-emitter threshold voltage
• One-button operation, automatic shutdown to avoid unnecessary battery drainage
• Short detection time: only 1.7 seconds (it is normal to take 1 minute for bulk capacitor detection)

Notice:

1. Before using the device to measure the capacitor, please discharge the capacitor first
2. Using the device while charging is prohibited.
3. The ESR and Vloss of the capacitor are only displayed when they are valid
4. On or Off voltage of the FET must be less than 5V
