8233D PRO-EN

● If diode is shorted, the display shows 0 (zero) in both direction.

● If display shows “OL” in both direction, the diode is open.

5.3.2. Continuity Check:

① Press the “FUNC” key to enter to the continuity mode.

② The buzzer sound if the resistance of a circuit under test is less than 100

Ω.

5-4. Frequency measurement

① Set the rotary switch to “Hz” position.

② Insert the red test lead into the “ VΩHz” input terminal and the black test

lead into the “COM” terminal.

③ Connect the test leads across with the circuit under testing. The measured

value shown.on the LCD display.

NOTE: Input signal level must be higher than 0.5V (it is sensitivity).

5-5. DC/AC µA or mA measurement

DC Current range is 200.0µA/2000µA and 20.00mA,/200.0mA and then 10A

range.

AC Current range is 200.0µA/2000µA and 20.00mA,/200.0mA and then 10A

range.

① Turn off power to the circuit. Set the rotary switch to the

properDC/AC µA or DC/AC mA position.

② Break the current path to be tested. Connect the red test lead to the

more positive side of the break and the black test lead to the more

negative side of the break.

③ Turn on power to the circuit. The measured value show on the

display.

5-6. DC/AC 10A measurement

① Insert the red test lead into the input terminal marked as “10A”.

② The measuring procedure is same as that of 5-5 section..
