Note
The test leads can add 0.1
¡
to 0.2
¡
of error to
resistance measurement. To obtain precision
readings in low-resistance measurement, that is the
range of 800.00
¡
, short-circuit the input terminals
beforehand, using the relative measurement function
button
REL
to automatically subtract the value
measured when the testing leads are short-circuit
from the reading.
For high-resistance (higher than 1M
¡
), it is normal
that it will take several seconds to obtain a stable
reading.
When measure resistance higher than 12.5M
¡
,
conductance value can be displayed by pressing
HOLD
. To switch to resistance value, press
HOLD
again.
Although it is possible to select frequency and duty
cycle measurement mode, these functions cannot
be used.
Although it is possible to select frequency and duty
cycle measurement mode, these functions cannot
be used.
When the resistance or conductance test has been
completed, disconnect the connection between the
testing leads and the circuit under test, and remove
the testing leads away from the input terminals of
the Meter.
