. OPERATION MIN - Minimum reading • Displays the minimum reading during the measurement. When the RPM function is being used the readings are shown in 10s of RPM, and to obtain the correct RPM readings they should be multiplied by 10. The minimum value is automatically reset when turning the unit off or it can be manually reset by momentarily pressing the Power On/Off / Reset button. 3.
• The first time the Sensitivity Decrease button is pressed, the display will show the sensitivity setting, each time the button is pressed again it will decrease the signal sensitivity of the TA300. A few seconds after the button is released the display will resume to show Maximum and Minimum readings. 3.5 Additional functions 3.5.1 Minimum and Maximum functions The TA300 maintains a continuous record of the minimum and maximum readings shown on the display.
4- While holding the Adjust increase) or (Trigger Level Adjust) button pressed, use the (Sensitivity (Sensitivity Adjust decrease) buttons to adjust the % value. Notes: • Adjusting the trigger level of the TA300 while performing RPM measurements, provides quick feedback on how this setting affects the response of the TA300 in any given situation. • The trigger level can be adjusted between 20% and 80%. The default value for the trigger level is 50%.
4.2.3 Weak signal due to the characteristics fuel line or fuel injection pump 5.2 Cleaning There are many factors that may contribute to the piezoelectric sensor in not being able to generate a signal (pulse) strong enough for the TA300 to detect. These situations may cause low, slow or inconsistent built up of fuel pressure in the fuel line. Some common causes are listed below: Keep the instrument in its carrying case when not in use and do not subject it to dampness or severe heat or cold.
