Allow at least 30 minutes for the unit to warm up so that it can stabilize.
3. OPERATION
3-1 Voltage Measurement
Voltage is the difference of electrical energy (potential) between two points.
Measuring voltage allows you to verify the following questions.
l Is voltage present? The presence of voltage tells you that the circuit is delivering
voltage to the component you are testing.
l What is the level of voltage? The voltage level tells you that whether the proper
voltage is arriving at the components.
l What is the voltage drop? The voltage drop tells you how much of voltage is
being consumed by the components.
WARNING---HIGH VOLTAGE
TO AVOID POSSIBLE ELECTRIC SHOCK AND/OR EQUIPMENT DAMAGE,
DO NOT ATTEMPT TO TAKE ANY VOLTAGE MEASUREMENTS IF THE
VOLTAGE IS ABOVE 1200V DC OR 1000V AC. THE "COM" TERMINAL
POTENTIAL SHOULD NOT EXCEED 500V TO THE GROUND.
(1) Plug the red and the black test leads into the VΩ and the COM input terminals
respectively.
(2) Verify dc or ac. Select the function (dc V or ac V) and set the range switch to the
desired volt range. For unknown voltage, always start from highest range and move
down to lower range to select scale for best reading.
(3) Connect the probe tips in parallel with the voltage source to be measured.
(4) Read voltage value on the Display.
3-2 Current Measurement
Current is the flow quantity of electrons through a conductor. Ampere is the amount
of electrons flowing through a conductor.
CAUTION
DO NOT ATTEMPT TO TAKE A CURRENT OF MORE THAN SPECIFIED.
