Before measuring small resistance. You must calibrate the multitester for exact measurement. Do not touch probe of the tester while calibrating.
Turn the multitester on.
Select the resistance range.
- O.L (Off Limite : Infinite) is displayed on the screen.
0 Ω must be displayed on the screen while contacting (+), (-) probes.
Resistance is displayed on the screen while contacting (+), (-) probes.
Press the REL△ function key.
Make sure that 0 Ω is displayed on the screen.
Turn the multitester on.
Select the resistance range (blow 200 Ω range).
- O.L (Off Limite : Infinite) or 1 is displayed on the screen.
0 Ω must be displayed on the screen while contacting (+), (-) probes.
Specific resistance of multitester is displayed on the screen while contacting (+), (-) probes.
Measure the resistance.
Subtract specific resistance of multitester from measured resistance.
ex) Measured resistance : 1.1 Ω , Specific resistance of multitester : 0.2 Ω
Exact resistance : 1.1 Ω ~ 0.2 Ω = 0.9 Ω
