Model UT90B: OPERATING MANUAL
Measurement Operation(7)
D.Resistance Measurement
( figure 7)
Warning
To avoid damages to the Meter or to the devices under
test, disconnect circuit power and discharge all the
high-voltage capacitors before measuring resistance.
To avoid harms to you, never attempt to measure
voltages higher than 60V DC/30V AC.
The resistance ranges are: 200.0 , 2.000k , 20.00k ,
200.0k , 2.000M and 20.00M .
To measure resistance, connect the Meter as follows:
1. Insert the red test lead into the V
the black test lead into the COM terminal.
2. Set the rotary switch to
3. Parallel connect the test leads across with the object
being measured.
4. The measured value shows on the display.
Note
l The LCD displays 1 indicating open-circuit for the
tested resistor or the resistor value is overload.
l The test leads can add 0.1 to 0.2 of error to
