How to use(Ohm meter: DT-R500) !

1.Gently press a ONa switch and the screen will appear.
And either put both ends of the line on the terminal or put the test code into contact with the line and then a resistance value will be appearing.
If pre-calculated resistance value were different from the measured value on the LCD, It may mean some problems on the wiring circuit line and then check the wiring .

2.Calculation of total resistance on the circuit line.
(Series Resistance) R= R1+R2+R3
(Parallel Resistance)
1
R= --------------------------
1 1 1
---- + ---- + ----
R1 R2 R3

(Total Resistance in combined series and parallel)

R = -------------------------------- + -----------------------------------------
1 1 1 1 1 1
------ + ----- + ----- ------ + ------ + --------
R1 R2 R3 R4 R5 R6
Caution when operating:
1.Subminiature battery LR44 is used.
2.If bumped into or placed in high degree or wet place, could be resulted in malfunction.
3.Dona t replace any inner parts without consulting us, that could cause a safety problem.
