4 Using the Digital Multimeter Functions
100 Agilent U1602B/U1604B User’s and Service Guide
Ohmmeter
The ohmmeter provides measurements for resistance, continuity test,
capacitance and diode test. The instrument automatically select the range
using auto- range. However, you can manually adjust the range of the
measurement, giving faster performance. Refer to “Auto- range Mode 115”
in this section for more detailed information.
Resistance Measurement
To perform resistance measurement, do the following instructions:
1 Press button to access meter menu.
2 Press F2 to access ohmmeter submenu.
3 In the ohmmeter submenu, press F1 to select the resistance
measurement from the pull- up menu.
4 Connect the red test lead to the input terminal and the black
test lead to the COM terminal.
5 Probe the test point of the circuit or device under test.
6 Read the resistance reading from the display. The display indicates the
proper decimal point, value and symbols.
7 To perform relative function, please refer to “Relative Function 112”
section in this chapter.
Disconnect power to the device or circuit under test and discharge all high voltage
capacitors to avoid electric shock and prevent possible damage to the instrument or
device under test while taking resistance measurement.
