INTRODUCTION:
The In-circuit ESR & DCR capacitor tester is specially designed to
measure ESR (equivalent Series Resistance) on capacitors in the range of
0.47uf and up, in or out of circuit. The output test frequency of the meter
is a 100KHz SINE WAVE. The output voltage is 15mV pp and will not
turn on any solid state devices in the circuit under test.
It includes a one-handed tweezers test probe, microprocessor controlled,
automatically discharges the capacitors under test, checks for low DCR,
checks and displays ESR on a 25 segment LED bar scale, and beeps from
one to five beeps depending on the ESR reading of the capacitor. It has a
three-colored chart on the front panel that show typical ESR readings of
good, fair, and bad capacitors depending on their capacitance.
OPERATION:
1.
Place the mode switch
to the position for measurement.
2.
Turn the unit on and wait for it to beep once to indicate it is ready.
3.
Hold the tweezers’ test probe cross the capacitor leads to measure
ESR of the capacitor
4.
Read the ESR of the capacitor according to the LED bar scale and
three-colored chart.
APPLICATIONS:
Using the tester to measure electrolytic capacitors in or out of circuit,
When the meter is turned on, it will automatically calibrate the internal circuit,
and then it will beep once to indicate it's ready. (Note: Before the unit beeps to
signal it is ready, don't have the tweezers’ test probes shorted together or
connected to a capacitor, otherwise the meter will continue to sound an alarm
until the test probe is opened or the capacitor is removed.)
The meter has two modes for performing in-circuit ESR measurements ("DCR
& ESR" mode and "ESR" mode). Place the mode switch
to the position for
measurement.
