DCR cycle.
If the meter stops on the DCR cycle, it first sounds an alarm and turns on the
DCR LOW led, then indicates DC resistance by flashing the LED
on the LED
bar and also sounds one or more times depending on the DC resistance (see table
2).
Table 2
The meter automatically discharges capacitors before testing. However, if
capacitors are large enough, and there is enough voltage stored, it may damage
the test probe. We recommend that for a large capacitor, you should discharge it
before you
test it.
You can use the "ESR" mode to test a capacitor with a parallel inductor if the
inductor has a large inductance at 100 kHz test frequency and have no affect on
the ESR reading. For example, there are motor, switch power supply transformer
and TV yoke windings etc.
On the "ESR" mode, the meter is an AC ohm meter, it can be used to measure
low value non-inductive resistors. It also may be used to measure small inductors
and compare meter reading to the known good inductors.
