Measuring Resistance - CAMBRIDGE EM830 Serie Manual Del Usuario

Note: 1. If the magnitude of the current to be measured is
not known beforehand, connect the red test lead to the "10A"
terminal and set the range switch to the
2. If the red test lead is connected to the "10A" terminal, the
range switch must be set in the

Measuring Resistance

1. Connect the black test lead to the "COM" terminal.
Connect the red test lead to the
2. Set the range switch to desired Ω range position.
3. Connect the test leads across the object to be measured.
4. Read the display reading.
Note:
1. For measurements >1MΩ, the meter may take a few
seconds to stabilize reading. This is normal for high
resistance measurements.
2. When the input is not connected, i.e. at open circuit,
"OL" will be displayed as an overrange indication.
3. Before making in-circuit resistance measurement,
disconnect all power to the circuit to be tested and
discharge all capacitors thoroughly.
Diode Test
1. Connect the black test lead to the "COM" terminal.
Connect the red test lead to the
Note: The polarity of the red lead is positive "+".)
2. Set the range switch to desired
3. Connect the red test lead to the anode of the diode to be
tested and the black test lead to the cathode of the diode.
4. The display shows the approximate forward voltage
drop of the diode. If the connection is reversed, "OL" will
be shown on the display.
Continuity Test (EM380, EM830C and
EM830D only)
1. Connect the black test lead to the "COM" terminal.
Connect the red test lead to the
