Page 7: Operation
Analog Bar Graph • The bar graph provides an analog indication of the measured input. For most measurement functions, the bar graph updates 10 times per second. • Using MAX MIN • The MAX MIN mode stores minimum (MIN) and maximum (MAX) input values. When the input goes below the stored minimum value or above the stored maximum value, the meter beeps and stores the new value. -
Page 8: Measuring Current
Measuring Current • To measure AC or DC current proceed as follows: Turn off power to the circuit. Discharge all high- voltage capacitors. Insert the red test lead into the mAµA or A terminal and black test lead into the COM terminal. - Page 9 • When testing the resistance signal from the calibrator, it is necessary to press and hold the RANGE while turning on the meter to change the maximum display to 4000 counts but the accuracy remains unchanged. • When resistance measurement has been completed, disconnect the test leads from the circuit under test and remove test leads from the input terminals of the meter.

Page 10: Measuring Capacitance
Measuring Capacitance • To ensure accuracy, the meter will first internally discharge the capacitor under test. DIS.C will show on the display. Depending upon the size of the capacitor and the amount of discharge required, this process may take some time. •... - Page 11 Measuring Temperature Note: Do not apply voltage to the test leads when the meter is in temperature measuring mode. Set the range selector to F, the display shows OL. Short circuit the test leads to show the room temperature. The meter is default to Celsius degree unit, you can change units by press the BLUE button once you have selected the temperature function.
- Page 12 If there is no interval time set to store the reading, each press of STORE increments the reading by one index number. • The maximum number of stored reading is 100 (for 72-7730A) and 9999 (for 72- 7732A) When the stored readings memory is full, the meter will stop storing data. •...
