വയറിംഗ് ഡയഗ്രം
Image: A detailed wiring diagram illustrating how to connect the KETOTEK KT-D138 digital multimeter with an external shunt for accurate voltage and current measurements in a DC circuit.
- Connect the positive terminal of the DC power supply to the red thin wire മീറ്ററിൻ്റെ.
- Connect the negative terminal of the DC power supply to the black thin wire മീറ്ററിൻ്റെ.
- Connect the positive terminal of the load to the red thick wire മീറ്ററിൻ്റെ.
- Connect the negative terminal of the load to one end of the external shunt.
- Connect the other end of the external shunt to the black thick wire മീറ്ററിൻ്റെ.
- Ensure all connections are secure and correct before applying power. Incorrect wiring can damage the product.
പ്രധാനപ്പെട്ടത്: The load cannot exceed the rated voltage and current of the meter (DC 6.5-100V, 100A). This device is designed for indoor use only.
പ്രവർത്തന നിർദ്ദേശങ്ങൾ
Once properly wired and powered on, the meter will display voltage, current, power, and energy readings on its LCD screen. The device has a single button for various functions.

ബട്ടൺ പ്രവർത്തനങ്ങൾ:
- ഷോർട്ട് പ്രസ്സ്: Toggles the backlight ON/OFF.
- ദീർഘനേരം അമർത്തുക (3 സെക്കൻഡ്): Resets the energy (kWh) accumulation. The energy value will flash, then release the button. Press again to confirm reset, or long press again to cancel.
- ക്രമീകരണം വോളിയംtage Alarm Threshold:
- Press and hold the button for 6 seconds until the voltage value flashes.
- Short press to adjust the alarm voltage value. The value will increase by 0.5V with each press.
- Long press for 3 seconds to save the setting and exit.
The meter will automatically store data when power is removed, ensuring that accumulated energy readings are not lost.
