Measurement Operation (6)
Note
l 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 340.0 , short-circuit the input terminals
beforehand and record the reading obtained (called
this reading as X). (X) is the additional resistance
from the test lead.
Then use the equation:
measured resistance value (Y) - (X) = precision
readings of resistance.
l For high-resistance measurement (>1M ), it is
normal taking several seconds to obtain a stable
reading.
l If reading with shorted test leads is not 0.5 ,
check for loose test leads, incorrect function selection,
or enabled Data Hold function.
l The LCD displays
indicating open-circuit for the
tested resistor or the resistor value is higher than
the maximum range of the Meter.
l When resistance measurement has been completed,

Model UT60D: OPERATING MANUAL
Analogue Bar Graph Display
The analogue bar graph likes the needle in a traditional
analogue meter (AMM). It refreshes 10 times a sec,
which is much faster than that of digital display and is
applied to zero adjustment and observation of rapidly
changing signal that make digital display hard to read.
The analogue display is divided uniformly into 10 scales
and composed of 34 segments; of which the full-range
value corresponds to the full-range value of the
measurement range that has been selected. The polarity
of the measured value is displayed as "-" on the left of
the analogue display: positive polarity is not displayed.
For example, when 34V range is selected, the full-range
value of the analogue display is 34V, and as the full
range is uniformly divided into 34 grades, each grade
denotes 1V. If the input is 17V, the high-lighted bar-shape
will be at the position indicated by the number 17. if the
input is -17V, a "-" sign will appear on the left of the
analogue display.
