OPA-102/101 SECTION 3. INTRODUCTION OF THE PRODUCT 3-1 Introduction This opacity meter measures a diesel smoke density of automobile burning diesel as fuel to diagnose the condition of automobile and provide preventive maintenance in order to avoid air pollution. Outlook appearance 3-2-1.
OPA-102/101 Display and Function Key structure ① DISPLAY : Select display screen ② ACCEL : FREE ACCELERATION TEST (Inspection mode) ③ HOLD : Holding the displayed screen (Ref.8-3. Hold set-up) There are two kinds of hold mode, which are HOLD and PEAK HOLD.
OPA-102/101 SECTION 4. MECHANICAL CIRCUIT 4-1 Principle of Measurement Attach light source at the end of the sample-shell where smoke pass through and attach detecting part at the other end of the sample-shell, and it detects the smoke density then converting it into figures and display.
Connect all of cables to the correct port each other on the side of measurement unit. And connect the probe hose on the rear of the measurement unit. Move the ON/OFF switch to “ON” position. Then OPA-102 will be start. ◈ Handheld terminal The handheld terminal is operated together with the display of the measurement at the same time.
OPA-102/101 SECTION 6. INITIAL DISPLAY 6-1 Warming up Switch the power [ON]. OPA-102 will perform the initialization process for about 10 seconds. Opacity Smokemeter Opacity Smokemeter OPA- The warming up will be performed for 3~6 minutes. Opacity Smokemeter WARM The initial calibration is automatically performed once the warming up is over.

OPA-102/101 7-2. Free(Snap) acceleration test (Normal mode) ★ For normal mode of free snap acceleration test, set HOLD mode in the setting menu to PEAK HOLD mode. (1) After reaching peak revolution speed by burst acceleration of engine of the testing vehicle in neutral gear (idling status), idle the engine for 2 seconds and maintain the idling status for 5~6 seconds.
OPA-102/101 7-3. Free(Snap) acceleration test (Inspection mode) (1) After reaching peak revolution speed by burst acceleration of engine of the testing vehicle in neutral gear (idling status), idle the engine for 2 seconds and maintain the idling status for 5~6 seconds. Repeat this process three times.

OPA-102/101 (11) This shows it’s ready for the third test and when you press [SET] KEY once more, you will see one flashing LED and at the buzzer sound, the test will start. (From this time on, the peak point of exhaust emissions will be renewed.) When you use [DISPLAY KEY, you will see “K (m...
OPA-102/101 (14) If the gap between the maximum and the minimum of exhaust emissions density tested three times is larger than 5% or the final test result is over the acceptable limits for exhaust emissions, an additional test will be done once more automatically and up to maximum 5 times.
OPA-102/101 SECTION 8. SET-UP Pressing [SET] key, it moves to SET-UP mode. Pressing [SET] key, it moves to [ CAL → YEAR → DATE → TIME → HOLD → PRT → CYL → VERSION → TEST → BT-R(handheld terminal reset) ] in sequence.
OPA-102/101 When setting up is completed, save and move to “Time set-up” by pressing [SAVE] key. When the “time set-up” is completed by pressing [SAVE] key, it is finished. 8-3. Hold set-up At Set-up mode, by using [SET] key, move to Hold mode set-up screen.
OPA-102/101 8-4. Printing density set-up At Set-up mode, by using [SET] key, move to printing density set-up screen. Pressing [SELECT] key, current set-up value is blinking. ▼ By pressing [▲, ] key, it moves to [ 05 → 25 ] in sequence.
