Model UT804: OPERATING MANUAL
When measuring low resistance, the test leads can
add 0.1 to 0.2
of error to resistance measurement.
To test the leads, touch the probe tips together and
read the resistance of the leads. If necessary, you
can press
REL
∆
to automatically subtract this value.
For high-resistance measurement (>1M ), it is
normal taking several seconds to obtain a stable
reading. In order to obtain precision readings, use
the test lead as short as possible.
The LCD displays
OL
indicating open-circuit or the
tested resistor value is higher than the maximum
range of the Meter.
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 connection between the testing leads
and the circuit under test and remove testing leads
away from the input terminals.
