1. This function is designed to check the HI LOW logic states of IC s and circuits by direction of the arrow on the LCD For TTL circuits the arrow will point downward at or below 2 9 volts and upward at or above 3 2 volts For 3V CMOS the arrow will point downward at or below 1 7 volts and upward at or above 2 0 volts For 5V CMOS the arrow will point downward at or below 3 1 volts and upwards at or above 3 4 volts When the BZ is also activated the 440 buzzer will sound when HI logic levels are measured E SPECIAL DMM FEATURES AND FUNCTIONS 1 REL Range ACV DCV OHM DC AC yA mA A REL stands for relative When a reading is measured that is wanted as a standard pushing the REL function will display the variance from the standard for all subsequent readings This is useful for matching components in circuits a Obtain a stable reference reading on the 440 b Push the REL F1 button on the 440 c The REL value will be displayed just above the function button menu on the lower portion of the LCD d Measure subsequent items e The LCD will display the difference between the REL stored value and the measured value 2 PEAK HOLD Range ACV DCV DC AC yA mA A The 440 displays the MAX and MIN readings for the main function being measured 3 2 Range OHM DIODE LOGIC Pushing the BZ button activates the Continuity Buzzer The buzzer sounds when the resistance measured is lt 100 Ohms Note The following items are2.
