Capacitance Measurement; Frequency Measurement - ADInstruments True RMS AD-9962 Manual De Usuario

_______________________________________________________________________________
Note the meter reading.
5. Reverse the probe polarity by switching probe position. Note this reading.
6. The diode or junction can be evaluated as follows:
A. If one reading shows a value and the other reading shows OL, the diode is
good.
B. If both readings show OL, the device is open.
C. If both readings are very small or zero, the device is shorted.
NOTE: The value indicated in the display during the diode check is the forward
voltage.

CAPACITANCE MEASUREMENT

WARNING: To avoid electric shock, discharge the capacitor under test before
measuring.
1. Set the function switch to the CAP capacitance position. Press the MODE button
until "nF" appears in the display.
2. Insert the black test lead banana plug into the negative COM jack and the red test
lead banana plug into the CAP positive jack.
3. Touch the test probe tips across the part under test.
4. Read the capacitance value in the display.
5. The display will indicate the proper decimal point and value.
Note: For very large values of capacitance measurement time can be several minutes
before the final reading stabilizes. The bar graph is disabled in capacitance
measurement mode. The LCD displays DIS. C .Discharging through the chip is quite
slow. We recommend the user to discharge the capacitor with some other apparatus.

FREQUENCY MEASUREMENT

1. Set the function switch to the Hz position.
2. Insert the black test lead banana plug into the negative (COM) jack and the red
test lead banana plug into the positive Hz jack.
3. Touch the test probe tips to the circuit under test.
4. Read the frequency in the display. The digital reading will indicate the proper
decimal point, symbols ( Hz ,kHz, MHz) and value.
