OPERATION
•
Plug the instrument in and check the 9V battery. If it is low the "
symbol will display, meaning the battery needs replacing.
•
The
besides the probe jack indicates that the input voltage or current
!
should not exceed the specified limits, in orderto protect the internal
circuit.
•
Before measurement, turn the function/range switch to the desired range.
Direct Voltage Measurement
•
Insert the red probe into the "VΩmA" jack and the black one into the COM
jack.
•
Turn the function/range switch to the range of V
to the power supply or load to be measured. The polarity touched by the
red probe will be on the display.
Notice
•
If you do not know the measured voltage range in advance, set the
function/range switch to the maxium range and then gradually turn to
smaller ranges until you reach a satisfactory resolution.
•
If the display shows " 1 ", this indicates an overrange measurement,
therefore the switch should be set to a higher range.
•
Do not input a voltage of more than 600V. It is capable of indicating a
higher voltage, but with the risk of damaging the inside circuit.
•
When taking the measurement of high voltage, pay special attention to
avoid an electric shock.
