Measurement Ranges(1)

A measurement range determines the highest value the
Meter can measure. Most Meter functions have more
than one range. See “Accuracy Specifications.”

A. Selecting a Measurement Range

Being in the right measurement range is important:
l If the range is too low for the input, the Meter displays
OL to indicate an overload.
l If the range is too high, the Meter will not display the
most accurate measurement.

B. Manual Ranging and Autoranging

The Meter has both manual range and autorange options:
l In the autorange mode, the Meter selects the best
range for input signals.
This allows you to switch test points without having
to reset the range.
l In the manual range mode, you may select the range.
This allows you to override autorange and lock the
Meter in a specific range.

The Meter defaults to the autorange mode in measurement
functions that have more than one range. When the
Meter is in the autorange mode, is displayed.

To enter and exit the manual range mode:

1. Press RANGE.
The Meter enters the manual range mode and

turns off.
Each presses of RANGE increments the range. When
the highest range is reached, The Meter wraps to the
lowest range.

2.To exit the manual range model, press and hold

RANGE for over 1 second.

in low-resistance measurement (UT60F: 400Ω and
UT60G is 600Ω), short-circuit the input terminals
beforehand and record the reading obtained (called
this reading as X).
Then use the equation:
measured resistance value (Y) –(X) = precision
readings of resistance.
l For high-resistance measurement (>1MΩ), it is normal
taking several seconds to obtain a stable reading.
l If Ω reading with shorted test leads is not 0.5Ω,
check for loose test leads, wrong function selected,
or enabled data hold function.

Measurement Operation(7)

Model UT60F/G: OPERATING MANUAL

24

Note

l In a circuit, a good diode should still produce a forward
voltage drop reading of 0.5V to 0.8V; however, the
reverse voltage drop reading can vary depending
on the resistance of other pathways between the
probe tips.
l Connect the test leads to the proper terminals as
said above to avoid error display.
