6.1.1 [Voltage] Setting
Meauring volatge of UT5583 is 1.0V~1000VDC, when voltage <10V, the voltage step is 0.1V; when voltage
≥10V, the voltage step is 1V.
Setting Steps of Voltage
1.
In the stop state, press [Test] key to enter the test page or press [Setup] key to enter the main
setting page.
2.
Use the arrow key to select the [Voltage] field.
3.
Use the function key at the bottom of the screen to direct select the pre-set voltage or use numeric
keyboard to input voltage value.
6.1.2 Test [Speed]
The instrument provides three test speed (slow, middle and fast). The slower the speed, the more
accurate and stable the test result.
Usually, when the user manually tests the device, use slow speed. If used for PLC and other automation
equipment online test, please choose middle or fast speed.
In general, use slow speed when test device
Setting Steps of Test Speed

6.1.3 Test [Range]
Refer to section 14 Specification to learn more about the resistance range in different voltage and
scale.
The accurate range is relate to the accuracy of measurement. The wrong range will make the
measurement results unable to achieve the required accuracy.
There are three ways of measuring range.
