Note
••
The test leads can add 0.1
Ω
Ω
to 0.2
Ω
Ω
of error to resistance measurement. To obtain precision readings in low-resistance
measurement, that is the range of 400.0
Ω
Ω
, 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-circuited from the reading
.
Measurement Operation (4)
If
Ω
Ω
reading with shorted test leads is not
≤≤
0.5
Ω
Ω
, check for loose test leads, incorrect function selection, or enabled Data Hold
function.
For high-resistance measurement
(>1M
Ω
Ω
),
it is normal to take several seconds to obtain a stable reading.
The LCD displays
indicating open-circuit for the tested resistor or the resistor value is higher than the maximum range of the Meter.
When resistance measurement 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.
D.Testing for Continuity
(see figure 6)
Warning
To avoid damages to the Meter or to the devices under test, disconnect circuit power and discharge all the high-voltage capacitors
before testing for continuity.
To test for continuity, connect the Meter as below:
1. Insert the red test lead into the
HzV
Ω
Ω
terminal and the black test lead into the
COM
terminal.
2. Model UT60C Set the rotary switch to
and press
BLUE
button to select
measurement mode.
