Note: The following parameters need to be known: Circuit Work Voltage, LED Work Voltage, LED
Work Current, Then you can calculate and obtain the series resistance value.
Calculate Formula: R=U/I=(Vi-Vd)/I.
Vi is the Circuit Work Voltage.
Vd is the LED Work Voltage.
I is the LED Work Current.
R is the series resistor.
E.g: Circuit Work Voltage Vi is 5V, LED Work Voltage Vd is 3V, LED Work Current I is10mA. So the
resistor’s work voltage is Vi-Vd=5V-3V=2V. Steps:
3.1>.Press ‘ON’ button to power ON.
3.2>.Press ‘MODE’ button to switch to ‘Rled Vi-Vi= V I= mA R= ’ display interface.
3.3>.Press ‘√’ button to input LED Work Current.
3.4>.Press the buttons ‘ 1 ’, ‘ 0 ’ and ‘ = ’ in sequence.
3.5>.Automatically Calculate and display Results resistance value 200ohm.
3.6>.Press ‘AC’ button can be cleared to zero.
4>.Function-4:Decimal to Hexadecimal and Hexadecimal to Decimal.
E.g: Decimal to Hexadecimal. Steps:
4.1>.Press ‘ON’ button to power ON.
4.2>.Press ‘MODE’ button to switch to ‘10HEX-16HEX’ display interface.
4.3>.Input Decimal value and then can get a Hexadecimal value automatically.
4.4>.Press ‘AC’ button can be cleared to zero.
E.g: Hexadecimal to Decimal. Steps:
4.1>.Press ‘ON’ button to power ON.
4.2>.Press ‘MODE’ button to switch to ‘10HEX-16HEX’ display interface.
4.3>.Press ‘√’ button to switch to ‘16HEX-10HEX’ display interface.
4.4>.Input Hexadecimal value and then can get a Decimal value automatically.
4.5>.Press ‘AC’ button can be cleared to zero.
5>.Function-5: Arithmetic Square Root Calculator.
E.g: Calculate the value of ‘√4’. Steps:
5.1>.Press ‘ON’ button to power ON and display Basic Decimal Arithmetic Calculator.
5.2>.Press ‘√’ button to switch to ‘√0’ display interface at.
5.3>.Press the buttons ‘ 4 ’, and ‘ = ’ in sequence.
5.4>.Automatically Calculate and display Results resistance value 2.
5.5>.Press ‘AC’ button can be cleared to zero.
6>.CR2032 Battery: It is powered by two RC2032 batteries. Due to limited battery capacity, frequent
use or prolonged standby may result in low battery power and inability to function properly. Please
replace the batteries promptly.
7>.Automatic shutdown: Automatic power off without operation within 30 seconds.
